공개 메소드들

메소드 설명
Dispose ( ) : void

Disposes the underlying Stream.
VerifySupport ( [ mimeType ) : void

Verifies that a archives of a specific MIME type are supported.

보호된 메소드들

메소드 설명
ArchiveExtractor ( [ target ) : System

Prepares to extract an archive contained in a stream.
CombinePath ( [ relativePath ) : string

Combines the extraction TargetDir path with the relative path inside the archive (ensuring only valid paths are returned).
CreateDirectory ( [ relativePath, System.DateTime lastWriteTime ) : void

Creates a directory in the filesystem and sets its last write time.
CreateSymlink ( [ source, [ target ) : void

Creates a symbolic link in the filesystem if possible; stores it in a FlagUtils.SymlinkFile otherwise.
Dispose ( bool disposing ) : void
Finish ( ) : void

Performs any tasks that were deferred to the end of the extraction process.
OpenFileWriteStream ( [ relativePath, bool executable = false ) : FileStream

Creates a stream for writing an extracted file to the filesystem.
QueueHardlink ( [ source, [ target, bool executable = false ) : void

Queues a hardlink for creation at the end of the extracton process. This enables handling links to files that have not been extracted yet.
StreamToFile ( [ stream, [ fileStream ) : void

Helper method for WriteFile.

Can be overwritten for archive formats that don't simply write a Stream to a file.

WriteFile ( [ relativePath, long fileSize, System.DateTime lastWriteTime, [ stream, bool executable = false ) : void

Writes a file to the filesystem and sets its last write time.

비공개 메소드들

메소드 설명
Create ( [ stream, [ target, [ mimeType ) : ArchiveExtractor
Create ( [ path, [ target, [ mimeType = null, long startOffset ) : ArchiveExtractor
CreateHardlink ( [ source, [ target ) : void

Creates a hardlink in the filesystem if possible; creates a copy otherwise.
GetRelativePath ( [ entryName ) : string
RemoveExecutableBit ( string relativePath ) : void

Marks a file as no longer executable using the filesystem if possible, an FlagUtils.XbitFile file otherwise.
SetDirectoryWriteTimes ( ) : void

Sets the last write times of the directories that were recorded during extraction.

This must be done in a separate step, since changing anything within a directory will affect its last write time.

SetExecutableBit ( string relativePath ) : void

Marks a file as executable using the filesystem if possible; stores it in a FlagUtils.XbitFile otherwise.
