Constructor Detail

ZstdDecompressCtx

public ZstdDecompressCtx()

Create a context for faster compress operations One such context is required for each thread - put this in a ThreadLocal.

Method Detail

loadDict

public void loadDict(ZstdDictDecompress dict)

Load decompression dictionary

Parameters:

dict - the dictionary or `null` to remove loaded dictionary

loadDict

public void loadDict(byte[] dict)

Load decompression dictionary.

Parameters:

dict - the dictionary or `null` to remove loaded dictionary

decompressDirectByteBuffer

public int decompressDirectByteBuffer(java.nio.ByteBuffer dstBuff,
                                      int dstOffset,
                                      int dstSize,
                                      java.nio.ByteBuffer srcBuff,
                                      int srcOffset,
                                      int srcSize)

Decompresses buffer 'srcBuff' into buffer 'dstBuff' using this ZstdDecompressCtx. Destination buffer should be sized to be larger of equal to the originalSize

Parameters:

dstBuff - the destination buffer - must be direct

dstOffset - the start offset of 'dstBuff'

dstSize - the size of 'dstBuff'

srcBuff - the source buffer - must be direct

srcOffset - the start offset of 'srcBuff'

srcSize - the size of 'srcBuff'

Returns:

the number of bytes decompressed into destination buffer (originalSize)

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

close

public void close()

Specified by:
