CompressedBlockOutputStream

public CompressedBlockOutputStream(OutputStream os,
                                   int size)
                            throws IOException

Constructs a CompressedBlockOutputStream that writes to the given underlying output stream 'os' and sends a compressed block once 'size' byte have been written. The default compression strategy and level are used.

Throws:

IOException

CompressedBlockOutputStream

public CompressedBlockOutputStream(OutputStream os,
                                   int size,
