Constructor Detail

DeflateCompressorOutputStream

public DeflateCompressorOutputStream(OutputStream outputStream)
                              throws IOException

Creates a Deflate compressed output stream with the default parameters.

Parameters:

outputStream - the stream to wrap

Throws:

IOException - on error

DeflateCompressorOutputStream

public DeflateCompressorOutputStream(OutputStream outputStream,
                                     DeflateParameters parameters)
                              throws IOException

Creates a Deflate compressed output stream with the specified parameters.

Parameters:

outputStream - the stream to wrap

parameters - the deflate parameters to apply

Throws:

IOException - on error

Method Detail

write

public void write(int b)
           throws IOException

Specified by:

write in class OutputStream

Throws:

IOException

write

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

Overrides:

write in class OutputStream

Throws:

IOException

flush

public void flush()
           throws IOException

Flushes the encoder and calls outputStream.flush(). All buffered pending data will then be decompressible from the output stream. Calling this function very often may increase the compressed file size a lot.

Specified by:

flush in interface Flushable

Overrides:

flush in class OutputStream

Throws:

IOException

finish

public void finish()
            throws IOException

Finishes compression without closing the underlying stream.

No more data can be written to this stream after finishing.

Throws:

IOException - on error

close

public void close()
           throws IOException

Specified by:

close in interface AutoCloseable

Specified by:

close in interface Closeable

Overrides:

close in class OutputStream

Throws:

IOException
