C# 클래스 ICSharpCode.SharpZipLib.Tar.TarInputStream

The TarInputStream reads a UNIX tar archive as an InputStream. methods are provided to position at each successive entry in the archive, and the read each entry as a normal input stream using read().

공개 메소드들

메소드	설명
CopyEntryContents ( Stream outputStream ) : void	Copies the contents of the current tar archive entry directly into an output stream.
Flush ( ) : void	Flushes the baseInputStream
GetNextEntry ( ) : TarEntry	Get the next entry in this tar archive. This will skip over any remaining data in the current entry, if there is one, and place the input stream at the header of the next entry, and read the header and instantiate a new TarEntry from the header bytes and return that entry. If there are no more entries in the archive, null will be returned to indicate that the end of the archive has been reached.
Mark ( int markLimit ) : void	Since we do not support marking just yet, we do nothing.
Read ( byte buffer, int offset, int count ) : int	Reads bytes from the current tar archive entry. This method is aware of the boundaries of the current entry in the archive and will deal with them appropriately
ReadByte ( ) : int	Reads a byte from the current tar archive entry.
Reset ( ) : void	Since we do not support marking just yet, we do nothing.
Seek ( long offset, SeekOrigin origin ) : long	Set the streams position. This operation is not supported and will throw a NotSupportedException
SetEntryFactory ( IEntryFactory factory ) : void	Set the entry factory for this instance.
SetLength ( long value ) : void	Sets the length of the stream This operation is not supported and will throw a NotSupportedException
Skip ( long skipCount ) : void	Skip bytes in the input buffer. This skips bytes in the current entry's data, not the entire archive, and will stop at the end of the current entry's data if the number to skip extends beyond that point.
TarInputStream ( Stream inputStream ) : System	Construct a TarInputStream with default block factor
TarInputStream ( Stream inputStream, int blockFactor ) : System	Construct a TarInputStream with user specified block factor
Write ( byte buffer, int offset, int count ) : void	Writes a block of bytes to this stream using data from a buffer. This operation is not supported and will throw a NotSupportedException
WriteByte ( byte value ) : void	Writes a byte to the current position in the file stream. This operation is not supported and will throw a NotSupportedException

메소드 상세

CopyEntryContents() 공개 메소드

Copies the contents of the current tar archive entry directly into an output stream.

public CopyEntryContents ( Stream outputStream ) : void
outputStream	Stream	/// The OutputStream into which to write the entry's data. ///
리턴	void

Dispose() 보호된 메소드

Closes this stream. Calls the TarBuffer's close() method. The underlying stream is closed by the TarBuffer.

protected Dispose ( bool disposing ) : void
disposing	bool
리턴	void

Flush() 공개 메소드

Flushes the baseInputStream

public Flush ( ) : void
리턴	void

GetNextEntry() 공개 메소드

Get the next entry in this tar archive. This will skip over any remaining data in the current entry, if there is one, and place the input stream at the header of the next entry, and read the header and instantiate a new TarEntry from the header bytes and return that entry. If there are no more entries in the archive, null will be returned to indicate that the end of the archive has been reached.

public GetNextEntry ( ) : TarEntry
리턴	TarEntry

Mark() 공개 메소드

Since we do not support marking just yet, we do nothing.

public Mark ( int markLimit ) : void
markLimit	int	/// The limit to mark. ///
리턴	void

Read() 공개 메소드

Reads bytes from the current tar archive entry. This method is aware of the boundaries of the current entry in the archive and will deal with them appropriately

public Read ( byte buffer, int offset, int count ) : int
buffer	byte	/// The buffer into which to place bytes read. ///
offset	int	/// The offset at which to place bytes read. ///
count	int	/// The number of bytes to read. ///
리턴	int

ReadByte() 공개 메소드

Reset() 공개 메소드

Since we do not support marking just yet, we do nothing.

public Reset ( ) : void
리턴	void

Seek() 공개 메소드

Set the streams position. This operation is not supported and will throw a NotSupportedException
