Public Methods

Method Description
BZip2OutputStream ( Stream stream ) : System

Construct a default output stream with maximum block size

BZip2OutputStream ( Stream stream, int blockSize ) : System

Initialise a new instance of the for the specified stream, using the given blocksize.

Valid block sizes are in the range 1..9, with 1 giving the lowest compression and 9 the highest.

Flush ( ) : void

Flush output buffers

Read ( byte buffer, int offset, int count ) : int

Read a block of bytes

ReadByte ( ) : int

Read a byte from the stream advancing the position.

Seek ( long offset, SeekOrigin origin ) : long

Sets the current position of this stream to the given value.

SetLength ( long value ) : void

Sets the length of this stream to the given value.

Write ( byte buffer, int offset, int count ) : void

Write a block of bytes to the stream

WriteByte ( byte value ) : void

Write a byte to the stream.

Protected Methods

Method Description
Dispose ( bool disposing ) : void

Releases the unmanaged resources used by the BZip2OutputStream and optionally releases the managed resources.
