Constructor Detail

CompressedSliceOutput

public CompressedSliceOutput(OutputStream compressionStream,
                             ChunkedSliceOutput bufferedOutput,
                             Supplier<RcFileCompressor.CompressedSliceOutput> resetFactory,
                             Runnable onDestroy)

Parameters:

compressionStream - the compressed output stream to delegate to

bufferedOutput - the output for the compressionStream

resetFactory - the function to create a new CompressedSliceOutput that reuses the bufferedOutput

onDestroy - used to cleanup the compression when done
