Constructor Details

ZstdDirectBufferCompressingStream

public ZstdDirectBufferCompressingStream(ByteBuffer target,
 int level)
                                  throws IOException

Throws:

IOException

Method Details

flushBuffer

protected ByteBuffer flushBuffer(ByteBuffer toFlush)
                          throws 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:

IOException

recommendedOutputBufferSize

public static int recommendedOutputBufferSize()

setDict

public ZstdDirectBufferCompressingStream setDict(byte[] dict)
                                          throws IOException

Throws:

IOException

setDict

public ZstdDirectBufferCompressingStream setDict(ZstdDictCompress dict)
                                          throws IOException

Throws:

IOException

setFinalize

public void setFinalize(boolean finalize)

Enable or disable class finalizers If finalizers are disabled the responsibility fir calling the `close` method is on the consumer.

Parameters:

finalize - default `true` - finalizers are enabled
