C# 클래스 ICSharpCode.SharpZipLib.Tar.TarBuffer

The TarBuffer class implements the tar archive concept of a buffered input stream. This concept goes back to the days of blocked tape drives and special io devices. In the C# universe, the only real function that this class performs is to ensure that files have the correct "record" size, or other tars will complain.

You should never have a need to access this class directly. TarBuffers are created by Tar IO Streams.

공개 메소드들

메소드	설명
Close ( ) : void	Close the TarBuffer. If this is an output buffer, also flush the current block before closing.
CreateInputTarBuffer ( Stream inputStream ) : TarBuffer	Create TarBuffer for reading with default BlockFactor
CreateInputTarBuffer ( Stream inputStream, int blockFactor ) : TarBuffer	Construct TarBuffer for reading inputStream setting BlockFactor
CreateOutputTarBuffer ( Stream outputStream ) : TarBuffer	Construct TarBuffer for writing with default BlockFactor
CreateOutputTarBuffer ( Stream outputStream, int blockFactor ) : TarBuffer	Construct TarBuffer for writing Tar output to streams.
Initialize ( int archiveBlockFactor ) : void	Initialization common to all constructors.
IsEndOfArchiveBlock ( byte block ) : bool	Determine if an archive block indicates the End of an Archive has been reached. End of archive is indicated by a block that consists entirely of null bytes. All remaining blocks for the record should also be null's However some older tars only do a couple of null blocks (Old GNU tar for one) and also partial records
ReadBlock ( ) : byte[]	Read a block from the input stream.
SkipBlock ( ) : void	Skip over a block on the input stream.
WriteBlock ( byte block ) : void	Write a block of data to the archive.
WriteBlock ( byte buffer, int offset ) : void	Write an archive record to the archive, where the record may be inside of a larger array buffer. The buffer must be "offset plus record size" long.
WriteFinalRecord ( ) : void	WriteFinalRecord writes the current record buffer to output any unwritten data is present. Any trailing bytes are set to zero which is by definition correct behaviour for the end of a tar stream.
WriteRecord ( ) : void	Write a TarBuffer record to the archive.

Initialize() 공개 메소드

Initialization common to all constructors.

public Initialize ( int archiveBlockFactor ) : void
archiveBlockFactor	int
리턴	void

IsEndOfArchiveBlock() 공개 정적인 메소드

Determine if an archive block indicates the End of an Archive has been reached. End of archive is indicated by a block that consists entirely of null bytes. All remaining blocks for the record should also be null's However some older tars only do a couple of null blocks (Old GNU tar for one) and also partial records

public static IsEndOfArchiveBlock ( byte block ) : bool
block	byte	The data block to check.
리턴	bool

ReadBlock() 공개 메소드

Read a block from the input stream.

public ReadBlock ( ) : byte[]
리턴	byte[]

SkipBlock() 공개 메소드

Skip over a block on the input stream.

public SkipBlock ( ) : void
리턴	void

TarBuffer() 보호된 메소드

Construct a default TarBuffer

protected TarBuffer ( ) : System
리턴	System

WriteBlock() 공개 메소드

Write a block of data to the archive.

public WriteBlock ( byte block ) : void
block	byte	/// The data to write to the archive. ///
리턴	void

WriteBlock() 공개 메소드

Write an archive record to the archive, where the record may be inside of a larger array buffer. The buffer must be "offset plus record size" long.

public WriteBlock ( byte buffer, int offset ) : void
