public class DeflaterOutputStream

extends FilterOutputStream

See Also:

Deflater

buf

Output buffer for writing compressed data.

def

Compressor for this stream.

DeflaterOutputStream(OutputStream)

Creates a new output stream with a defaul compressor and buffer size.

DeflaterOutputStream(OutputStream, Deflater)

Creates a new output stream with the specified compressor and a default buffer size.

DeflaterOutputStream(OutputStream, Deflater, int)

Creates a new output stream with the specified compressor and buffer size.

close()

Writes remaining compressed data to the output stream and closes the underlying stream.

deflate()

Writes next block of compressed data to the output stream.

finish()

Finishes writing compressed data to the output stream without closing the underlying stream.

write(byte[], int, int)

Writes an array of bytes to the compressed output stream.

write(int)

Writes a byte to the compressed output stream.

protected Deflater def

Compressor for this stream.

protected byte buf[]

Output buffer for writing compressed data.

public DeflaterOutputStream(OutputStream out,
Deflater def,
                             int size)

Creates a new output stream with the specified compressor and buffer size.

Parameters:

out - the output stream

def - the compressor ("deflater")

len - the output buffer size

public DeflaterOutputStream(OutputStream out,
Deflater def)

Creates a new output stream with the specified compressor and a default buffer size.

Parameters:

out - the output stream

def - the compressor ("deflater")

public DeflaterOutputStream(OutputStream out)

Creates a new output stream with a defaul compressor and buffer size.

public void write(int b) throws IOException

Writes a byte to the compressed output stream. This method will block until the byte can be written.

Parameters:

b - the byte to be written

Throws: IOException

if an I/O error has occurred

Overrides:

write in class FilterOutputStream

public void write(byte b[],
                   int off,
                   int len) throws IOException

Writes an array of bytes to the compressed output stream. This method will block until all the bytes are written.

Parameters:

buf - the data to be written

off - the start offset of the data

len - the length of the data

Throws: IOException

if an I/O error has occurred

Overrides:

write in class FilterOutputStream

public void finish() throws IOException

Finishes writing compressed data to the output stream without closing the underlying stream. Use this method when applying multiple filters in succession to the same output stream.

Throws: IOException

if an I/O error has occurred

public void close() throws IOException

Writes remaining compressed data to the output stream and closes the underlying stream.

Throws: IOException

if an I/O error has occurred

Overrides:

close in class FilterOutputStream

protected void deflate() throws IOException

Writes next block of compressed data to the output stream.
