Constructor	Description
FastLZOutputStream(OutputStream stream, int compressionLevel)	Initializes a new instance of the FastLZStream class prepared for compression.

Method Summary

Modifier and Type	Method	Description
void	close()	Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream.
void	flush()	Clears all buffers for this stream and causes any buffered data to be written to the underlying device.
void	write(byte[] buffer, int offset, int count)	Writes a sequence of bytes to the compressing stream and advances the current position within this stream by the number of bytes written.
void	write(int b)	Writes the specified byte to this output stream.

Constructor Detail

FastLZOutputStream

public FastLZOutputStream(OutputStream stream,
                          int compressionLevel)

Initializes a new instance of the FastLZStream class prepared for compression.

Parameters:

stream - the stream for saving compressed data

compressionLevel - use 1 for faster compression, use 2 for better compression ratio

Throws:

com.aspose.ms.System.ArgumentNullException - stream is null.

com.aspose.ms.System.ArgumentException - stream does not support writing.

com.aspose.ms.System.ArgumentOutOfRangeException - compressionLevel is more than 2 or less than 1.

Method Detail

write

public void write(int b)

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Specified by:

write in class OutputStream

Parameters:

b - the byte

write

public void write(byte[] buffer,
                  int offset,
                  int count)

Writes a sequence of bytes to the compressing stream and advances the current position within this stream by the number of bytes written.

Overrides:

write in class OutputStream

Parameters:

buffer - an array of bytes. This method copies count bytes from buffer to the current stream

offset - the zero-based byte offset in buffer at which to begin copying bytes to the current stream

count - the number of bytes to be written to the current stream

flush

public void flush()

Clears all buffers for this stream and causes any buffered data to be written to the underlying device.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

close

public void close()

Closes the current stream and releases any resources (such as sockets and file handles) associated with the current stream.

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream
