ZstdDirectBufferCompressingStream

public ZstdDirectBufferCompressingStream(java.nio.ByteBuffer target,
                                         int level)
                                  throws java.io.IOException

Method Detail

flushBuffer

protected java.nio.ByteBuffer flushBuffer(java.nio.ByteBuffer toFlush)
                                   throws java.io.IOException

This method should flush the buffer and either return the same buffer (but cleared) or a new buffer that should be used from then on.

Parameters:

toFlush - buffer that has to be flushed (or most cases, you want to call Buffer.flip() first)

Returns:

the new buffer to use, for most cases the same as the one passed in, after a call to Buffer.clear().

Throws:

java.io.IOException
