           throws IOException

Specified by:

close in interface Closeable

Overrides:

close in class CompressorStream

Throws:

IOException

flush

public void flush()
           throws IOException

Specified by:

flush in interface Flushable

Overrides:

Throws:

IOException

write

public void write(byte[] data,
                  int offset,
                  int length)
           throws IOException

Description copied from class: CompressionOutputStream

Write compressed bytes to the stream. Made abstract to prevent leakage to underlying stream.

Overrides:

write in class CompressorStream

Throws:

IOException

finish

public void finish()
            throws IOException

Description copied from class: CompressionOutputStream

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

Overrides:

finish in class CompressorStream

Throws:

IOException

resetState

public void resetState()
                throws IOException

Description copied from class: CompressionOutputStream

Reset the compression to the initial state. Does not reset the underlying stream.

Overrides:

resetState in class CompressorStream

Throws:

IOException
