Public Methods

Method	Description
DeflaterOutputStream ( Stream baseOutputStream ) : System	Creates a new DeflaterOutputStream with a default Deflater and default buffer size.
DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater ) : System	Creates a new DeflaterOutputStream with the given Deflater and default buffer size.
DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater, int bufferSize ) : System	Creates a new DeflaterOutputStream with the given Deflater and buffer size.
Finish ( ) : void	Finishes the stream by calling finish() on the deflater.
Flush ( ) : void	Flushes the stream by calling Flush on the deflater and then on the underlying stream. This ensures that all bytes are flushed.
Read ( byte buffer, int offset, int count ) : int	Read a block of bytes from stream
ReadByte ( ) : int	Read a byte from stream advancing position by one
Seek ( long offset, SeekOrigin origin ) : long	Sets the current position of this stream to the given value. Not supported by this class!
SetLength ( long value ) : void	Sets the length of this stream to the given value. Not supported by this class!
Write ( byte buffer, int offset, int count ) : void	Writes bytes from an array to the compressed stream.
WriteByte ( byte value ) : void	Writes a single byte to the compressed output stream.

Protected Methods

Method	Description
Deflate ( ) : void	Deflates everything in the input buffers. This will call `def.deflate()` until all bytes from the input buffers are processed.
Dispose ( bool disposing ) : void	Calls Finish and closes the underlying stream when is true.
EncryptBlock ( byte buffer, int offset, int length ) : void	Encrypt a block of data
InitializeAESPassword ( ZipEntry entry, string rawPassword, byte &salt, byte &pwdVerifier ) : void	Initializes encryption keys based on given password.
InitializePassword ( string password ) : void	Initializes encryption keys based on given password.

Private Methods

Method	Description
GetAuthCodeIfAES ( ) : void

Method Details

Deflate() protected method

Deflates everything in the input buffers. This will call def.deflate() until all bytes from the input buffers are processed.

protected Deflate ( ) : void
return	void

DeflaterOutputStream() public method

Creates a new DeflaterOutputStream with a default Deflater and default buffer size.

public DeflaterOutputStream ( Stream baseOutputStream ) : System
baseOutputStream	Stream	/// the output stream where deflated output should be written. ///
return	System

DeflaterOutputStream() public method

Creates a new DeflaterOutputStream with the given Deflater and default buffer size.

public DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater ) : System
baseOutputStream	Stream	/// the output stream where deflated output should be written. ///
deflater	ICSharpCode.SharpZipLib.Zip.Compression.Deflater	/// the underlying deflater. ///
return	System

DeflaterOutputStream() public method

Creates a new DeflaterOutputStream with the given Deflater and buffer size.

/// bufsize is less than or equal to zero. /// /// baseOutputStream does not support writing /// /// deflater instance is null ///

public DeflaterOutputStream ( Stream baseOutputStream, Deflater deflater, int bufferSize ) : System
baseOutputStream	Stream	/// The output stream where deflated output is written. ///
deflater	ICSharpCode.SharpZipLib.Zip.Compression.Deflater	/// The underlying deflater to use ///
bufferSize	int	/// The buffer size in bytes to use when deflating (minimum value 512) ///
return	System

Dispose() protected method

Calls Finish and closes the underlying stream when is true.

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

EncryptBlock() protected method

Encrypt a block of data

protected EncryptBlock ( byte buffer, int offset, int length ) : void
buffer	byte	/// Data to encrypt. NOTE the original contents of the buffer are lost ///
offset	int	/// Offset of first byte in buffer to encrypt ///
length	int	/// Number of bytes in buffer to encrypt ///
return	void

Finish() public method

Finishes the stream by calling finish() on the deflater.

/// Not all input is deflated ///

public Finish ( ) : void
return	void

Flush() public method

Flushes the stream by calling Flush on the deflater and then on the underlying stream. This ensures that all bytes are flushed.

public Flush ( ) : void
return	void

InitializeAESPassword() protected method
