This class is used to control Compression for package parts.

Compression is turned off in this mode.

Compression is optimized for a reasonable compromise between size and performance.

Compression is optimized for size.

Compression is optimized for performance.

Compression is optimized for super performance.

Content Type class

This constructor creates a ContentType object that represents the content-type string. At construction time we validate the string as per the grammar specified in RFC 2616. Note: We allow empty strings as valid input. Empty string should we used more as an indication of an absent/unknown ContentType.

content-type If the contentType parameter is null If the contentType string has leading or trailing Linear White Spaces(LWS) characters If the contentType string invalid CR-LF characters

TypeComponent of the Content Type If the content type is "text/xml". This property will return "text"

SubType component If the content type is "text/xml". This property will return "xml"

Enumerator which iterates over the Parameter and Value pairs which are stored in a dictionary. We hand out just the enumerator in order to make this property ReadOnly Consider following Content type - type/subtype ; param1=value1 ; param2=value2 ; param3="value3" This will return an enumerator over a dictionary of the parameter/value pairs.

This method does a strong comparison of the content types, as parameters are not allowed. We only compare the type and subType values in an ASCII case-insensitive manner. Parameters are not allowed to be present on any of the content type operands.

Content type to be compared with

This method does a weak comparison of the content types. We only compare the type and subType values in an ASCII case-insensitive manner. Parameter and value pairs are not used for the comparison. If you wish to compare the parameters too, then you must get the ParameterValuePairs from both the ContentType objects and compare each parameter entry. The allowParameterValuePairs parameter is used to indicate whether the comparison is tolerant to parameters being present or no.

Content type to be compared with If true, allows the presence of parameter value pairs. If false, parameter/value pairs cannot be present in the content type string. In either case, the parameter value pair is not used for the comparison.

ToString - outputs a normalized form of the content type string

This method validates if the content type string has valid CR-LF characters. Specifically we test if '\r' is accompanied by a '\n' in the string, else its an error.

Parses the type and subType tokens from the string. Also verifies if the Tokens are valid as per the grammar.

substring that has the type and subType of the content type If the typeAndSubType parameter does not have the "/" character

Parse the individual parameter=value strings

This string has the parameter and value pair of the form parameter=value If the string does not have the required "="

This method returns the length of the first parameter value in the input string.

Starting index for parsing

Validating the given token The following checks are being made - 1. If all the characters in the token are either ASCII letter or digit. 2. If all the characters in the token are either from the remaining allowed cha----ter set.

string token validated string token If the token is Empty

Validating if the value of a parameter is either a valid token or a valid quoted string

parameter value string validate parameter value string If the parameter value is empty

This method validates if the text in the quoted string

Returns true if the input character is an allowed character Returns false if the input cha----ter is not an allowed character

input character

Returns true if the input character is an ASCII digit or letter Returns false if the input character is not an ASCII digit or letter

input character

Returns true if the input character is an ASCII letter Returns false if the input character is not an ASCII letter

Lazy initialization for the ParameterDictionary

This class is used to control Encryption RM for package parts.

Encryption is turned off in this mode. This is not supported.

RightsManagement is the only supported option right now.

This class ignores all calls to Flush() and Close() methods depending on whether the IgnoreFlushAndClose property is set to true or false. This has been created for performance improvements for the ZipPackage.

If the PackagePart does not exists in the underlying package then this method should return a null. This method must not throw an exception if a part does not exist.

This method is for custom implementation corresponding to the underlying file format. This method will actually delete the part from the underlying package. This method should not throw if the specified part does not exist. This is in conformance with the FileInfo.Delete call.

This method is for custom implementation corresponding to the underlying file format. This is the method that knows how to get the actual parts. If there are no parts, this method should return an empty array.

This method is for custom implementation corresponding to the underlying file format. This method should be used to dispose the resources that are specific to the file format. Also everything should be flushed to the disc before closing the package.

Subclasses that manage non-memory resources should override this method and free these resources. Any override should be careful to always call base.Dispose(disposing) to ensure orderly cleanup.

Protected constructor for the abstract Base class. This is the current contract between the subclass and the base class If we decide some registration mechanism then this might change You should use this constructor in the rare case when you do not have the content type information related to this part and would prefer to obtain it later as required. These parts have the CompressionOption as NotCompressed by default. NOTE : If you are using this constructor from your subclass or passing a null for the content type parameter, be sure to implement the GetContentTypeCore method, as that will be called to get the content type value. This is provided to enable lazy initialization of the ContentType property.

The Content type of the stream that is represented by this part. The PackagePart properties can not be accessed if the parent container is closed. The content type value can be provided by the underlying physical format implementation at the time of creation of the Part object ( constructor ) or We can initialize it in a lazy manner when the ContentType property is called called for the first time by calling the GetContentTypeCore method. Note: This method GetContentTypeCore() is only for lazy initialization of the Content type value and will only be called once. There is no way to change the content type of the part once it has been assigned.

Custom Implementation for the GetContentType Method This method should only be implemented by those physical format implementors where the value for the content type cannot be provided at the time of construction of Part object and if calculating the content type value is a non-trivial or costly operation. The return value has to be a valid ContentType. This method will be used in real corner cases. The most common usage should be to provide the content type in the constructor. This method is only for lazy initialization of the Content type value and will only be called once. There is no way to change the content type of the part once it is assigned.

Content type for the Part By default, this method throws a NotSupportedException. If a subclass wants to initialize the content type for a PackagePart in a lazy manner they must override this method.

The relative uri that represents the part within a package Returns a relative URI with an absolute path that points to a part within a package If partUri parameter is null If partUri parameter is an absolute Uri If partUri parameter is empty If partUri parameter ends with "/" If partUri parameter starts with two "/" If partUri parameter has a fragment

This method is used to resolve part Uris Constructs resolved relative URI from two relative URIs This method should be used in places where we have a a target URI in the PackageRelationship and we want to get the name of the part it targets with respect to the source part

This should be a valid partName. The only exception to this rule is an Uri of the form "/". This uri will only be used to resolve package level relationships. This Uri indicates that the relative Uri is being resolved against the root of the package. This URI can be any relative URI If either sourcePartUri or targetUri parameter is null If either sourcePartUri or targetUri parameter is an absolute Uri If sourcePartUri parameter does not conform to the valid partUri syntax

This method returns the relative uri between two given parts

The relative path between two parts If either the sourcePartUri or targetPartUri parameter is null If either sourcePartUri or targetPartUri parameter does not conform to the valid partUri syntax

Returns the normalized form of the part URI

Part Uri Normalized Part Uri If partUri is null If partUri parameter does not conform to the valid partUri syntax

This method compares two part uris and returns an int to indicate the equivalence Null values are allowed

First part Uri to be compared Second part Uri to be compared A 32-bit signed integer indicating the lexical relationship between the compared Uri components. Value - Less than zero means firstUri is less than secondUri Value - Equal to zero means both the Uris are equal Value - Greater than zero means firstUri is greater than secondUri If firstPartUri or secondPartUri parameter does not conform to the valid partUri syntax

IsRelationshipPartUri method returns a boolean indicating whether the Uri given is a relationship part Uri or not.

uri of part to evaluate true if the given part is a PackageRelationship part Does not inspect the part contents - this is based solely on the name If partUri parameter is null If partUri parameter is an absolute Uri If partUri parameter does not conform to the valid partUri Syntax

This method returns a relationship part Uri given a part Uri Example Input - partUri - /files/document.xaml Return - Relationship Uri - /files/_rels/document.xaml.rels If the input to the method is Uri - "/", then we will return /_rels/.rels as the relationship part Uri for the Package level relationships

Part Uri for which the relationship part Uri is wanted returns a Uri that conforms to the relationship part Uri syntax If the input Uri is a relationship part Uri itself If partUri parameter is null If partUri parameter is an absolute Uri If partUri parameter does not conform to the valid partUri Syntax

Given a valid relationship Part Uri, this method returns the source Part Uri for this relationship Part Uri. If the relationship part name is for the Package Level relationships [/_rels/.rels], we return a relative Uri of the form "/" indicating that it has no part as the parent, but is at the package level Example Input - Relationship Uri - /files/_rels/document.xaml.rels Returns -Source Part Uri - /files/document.xaml

relationship part Uri A uri that is a valid source part Uri for the relationship Uri provided If relationshipPartUri parameter is null If relationshipPartUri parameter is an absolute Uri If relationshipPartUri parameter does not conform to the valid partUri Syntax If the relationshipPartUri is not a relationship part Uri itself If the resultant Uri obtained is a relationship part Uri

This method is used to validate a part Uri This method does not perform a case sensitive check of the Uri

The string that represents the part within a package Returns the part uri if it is valid If partUri parameter is null If partUri parameter is an absolute Uri If partUri parameter is empty If partUri parameter does not start with a "/" If partUri parameter starts with two "/" If partUri parameter ends with a "/" If partUri parameter has a fragment If partUri parameter has some escaped characters that should not be escaped or some characters that should be escaped are not escaped.

pack scheme name

ValidatedPartUri class Once the partUri has been validated as per the syntax in the OPC spec we create a ValidatedPartUri, this way we do not have to re-validate this. This class is heavily used throughout the Packaging APIs and in order to reduce the parsing and number of allocations for Strings and Uris we cache the results after parsing.

This method is used to create a valid pack Uri

This is the uri that points to the entire package. This parameter should be an absolute Uri. This parameter cannot be null or empty This method will create a valid pack uri that references the entire package A Uri with the "pack://" scheme If packageUri parameter is null If packageUri parameter is not an absolute Uri

This method is used to create a valid pack Uri

This is the uri that points to the entire package. This parameter should be an absolute Uri. This parameter cannot be null or empty This is the uri that points to the part within the package This parameter should be a relative Uri. This parameter can be null in which case we will create a valid pack uri that references the entire package A Uri with the "pack://" scheme If packageUri parameter is null If packageUri parameter is not an absolute Uri If partUri parameter does not conform to the valid partUri syntax

This method is used to create a valid pack Uri

This is the uri that points to the entire package. This parameter should be an absolute Uri. This parameter cannot be null or empty This is the uri that points to the part within the package This parameter should be a relative Uri. This parameter can be null in which case we will create a valid pack uri that references the entire package Fragment for the resulting Pack URI. This parameter can be null The fragment string must start with a "#" A Uri with the "pack://" scheme If packageUri parameter is null If packageUri parameter is not an absolute Uri If partUri parameter does not conform to the valid partUri syntax If fragment parameter is empty or does not start with a "#"

This method parses the pack uri and returns the inner Uri that points to the package as a whole.

Uri which has pack:// scheme Returns the inner uri that points to the entire package If packUri parameter is null If packUri parameter is not an absolute Uri If packUri parameter does not have "pack://" scheme If inner packageUri extracted from the packUri has a fragment component

This method parses the pack uri and returns the absolute path of the URI. This corresponds to the part within the package. This corresponds to the absolute path component in the Uri. If there is no part component present, this method returns a null

Returns a relative Uri that represents the part within the package. If the pack Uri points to the entire package then we return a null Returns a relative URI with an absolute path that points to a part within a package If packUri parameter is null If packUri parameter is not an absolute Uri If packUri parameter does not have "pack://" scheme If partUri extracted from packUri does not conform to the valid partUri syntax

This method compares two pack uris and returns an int to indicate the equivalence.

First Uri of pack:// scheme to be compared Second Uri of pack:// scheme to be compared A 32-bit signed integer indicating the lexical relationship between the compared Uri components. Value - Less than zero means firstUri is less than secondUri Value - Equal to zero means both the Uris are equal Value - Greater than zero means firstUri is greater than secondUri If either of the Uris are not absolute or if either of the Uris are not with pack:// scheme If firstPackUri or secondPackUri parameter is not an absolute Uri If firstPackUri or secondPackUri parameter does not have "pack://" scheme

This method is used to validate the package uri

Escapes - %', '@', ',', '?' in the package URI This method modifies the string in a culture safe and case safe manner.

The package properties are a subset of the standard OLE property sets SummaryInformation and DocumentSummaryInformation, and include such properties as Title and Subject.

Setting a property to null deletes this property. 'null' is never strictly speaking a property value, but an absence indicator. The primary creator. The identification is environment-specific and can consist of a name, email address, employee ID, etc. It is recommended that this value be only as verbose as necessary to identify the individual. The title. The topic of the contents. The category. This value is typically used by UI applications to create navigation controls. A delimited set of keywords to support searching and indexing. This is typically a list of terms that are not available elsewhere in the properties. The description or abstract of the contents. The type of content represented, generally defined by a specific use and intended audience. Example values include "Whitepaper", "Security Bulletin", and "Exam". (This property is distinct from MIME content types as defined in RFC 2616.) The status of the content. Example values include "Draft", "Reviewed", and "Final". The version number. This value is set by the user or by the application. The revision number. This value indicates the number of saves or revisions. The application is responsible for updating this value after each revision. The creation date and time. The date and time of the last modification. The user who performed the last modification. The identification is environment-specific and can consist of a name, email address, employee ID, etc. It is recommended that this value be only as verbose as necessary to identify the individual. The date and time of the last printing. A language of the intellectual content of the resource A unique identifier.

The TargetMode enumeration is used to interpret the "base" uri for the PackageRelationship target Uri. Possible values - 0: "Internal" - target points to a part within the package PackageRelationship target uri must be relative. 1: "External" - target points to an external resource. The resource can be relative to the package entity or an absolute URI

TargetMode is "Internal". PackageRelationship target points to a part within the package PackageRelationship target uri must be relative.

TargetMode is "External". PackageRelationship target points to an external resource. PackageRelationship target uri can be relative or absolute. The resource can be relative to the package entity or an absolute URI.

handles mc:PreserveAttributes="foo:bar" attribute functionality is supported, but not implemented

helper method to generate an exception

CompatibilityScopes are used to handle markup-compatibility elements and attributes. Each scope stores the "previous" or parent scope, its depth, and an associated XmlCompatibilityReader. At a particular Reader depth, only one scope should be pushed.

ZipPackage is a specific implementation for the abstract Package class, corresponding to the Zip file format. This is a part of the Packaging Layer APIs.

This method is for custom implementation for the underlying file format Adds a new item to the zip archive corresponding to the PackagePart in the package.

PartName Content type of the part Compression option for this part If partUri parameter is null If contentType parameter is null If partUri parameter does not conform to the valid partUri syntax If CompressionOption enumeration [compressionOption] does not have one of the valid values

This method is for custom implementation specific to the file format. Returns the part after reading the actual physical bits. The method returns a null to indicate that the part corresponding to the specified Uri was not found in the container. This method does not throw an exception if a part does not exist.

This method is for custom implementation specific to the file format. Deletes the part corresponding to the uri specified. Deleting a part that does not exists is not an error and so we do not throw an exception in that case.

If partUri parameter is null If partUri parameter does not conform to the valid partUri syntax

This method is for custom implementation specific to the file format. This is the method that knows how to get the actual parts from the underlying zip archive.

Some or all of the parts may be interleaved. The Part object for an interleaved part encapsulates the Uri of the proper part name and the ZipFileInfo of the initial piece. This function does not go through the extra work of checking piece naming validity throughout the package. This means that interleaved parts without an initial piece will be silently ignored. Other naming anomalies get caught at the Stream level when an I/O operation involves an anomalous or missing piece. This function reads directly from the underlying IO layer and is supposed to be called just once in the lifetime of a package (at init time). An array of ZipPackagePart.

This method is for custom implementation corresponding to the underlying zip file format.

Closes the underlying ZipArchive object for this container

True if called during Dispose, false if called during Finalize

Internal constructor that is called by the OpenOnFile static method.

File path to the container. Container is opened in the specified mode if possible Container is opened with the specified access if possible Container is opened with the specified share if possible

Internal constructor that is called by the Open(Stream) static methods.

ExtensionComparer The Extensions are stored in the Default Dictionary in their original form, however they are compared in a normalized manner. Equivalence for extensions in the content type stream, should follow the same rules as extensions of partnames. Also, by the time this code is invoked, we have already validated, that the extension is in the correct format as per the part name rules.So we are simplifying the logic here to just convert the extensions to Upper invariant form and then compare them.

This is a helper class that maintains the Content Types File related to this ZipPackage.

Initialize the object without uploading any information from the package. Complete initialization in read mode also involves calling ParseContentTypesFile to deserialize content type information.

Find the content type stream, allowing for interleaving. Naming collisions (as between an atomic and an interleaved part) will result in an exception being thrown. Return null if no content type stream has been found.

The input array is lexicographically sorted

This class represents a Part within a Zip container. This is a part of the Packaging Layer APIs. This implementation is specific to the Zip file format.

Custom Implementation for the GetStream Method
