Constructor Detail

GZIPOutputStream

public GZIPOutputStream(OutputStream out,
                        int size)
                 throws IOException

Class is disabled.

Creates a new output stream with the specified buffer size.

Parameters:

out - the output stream

size - the output buffer size

Throws:

IOException - If an I/O error has occurred.

IllegalArgumentException - if size is <= 0

GZIPOutputStream

public GZIPOutputStream(OutputStream out)
                 throws IOException

Class is disabled.

Creates a new output stream with a default buffer size.

Parameters:

out - the output stream

Throws:

IOException - If an I/O error has occurred.

Method Detail

write

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

Class is disabled.

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

Overrides:

write in class DeflaterOutputStream

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.

FilterOutputStream.write(int)

finish

public void finish()
            throws IOException

Class is disabled.

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.

Overrides:

finish in class DeflaterOutputStream

Throws:

IOException - if an I/O error has occurred
