Interfaces

These interfaces define the structure for providing access to underlying file data and creating instances of file data, particularly useful for unpacking purposes.

IFileData Interface

The IFileData interface provides access to underlying file data. This is particularly useful for read operations where the entire file is not yet available, such as over a network; you should stall until you can provide enough data.

Properties

• Data: A pointer to the data of the underlying item.
• DataLength: The length of the underlying data.

IFileDataProvider Interface

The IFileDataProvider interface creates IFileData instances for the purposes of getting data for the archiving operation.

Methods

• GetFileData(ulong start, ulong length): Gets the file data behind this provider.

IOutputDataProvider Interface

The IOutputDataProvider interface creates IFileData instances which allow the user to output information for unpacking purposes. Note that items are disposed upon successful write to target, not explicitly by the user.

Properties

• RelativePath: The relative path to the output location.
• Entry: The entry this provider is for.

Methods

• GetFileData(ulong start, ulong length): Gets the output data behind this provider. Returns an individual IFileData buffer to write decompressed data to. Make sure to dispose, for example with a 'using' statement.
