public final int decodeChunk(final InputStream is, final byte[] inputBuffer, final byte[] outputBuffer) throws IOException

Implements abstract com.ning.compress.lzf.ChunkDecoder.decodeChunk.

Doc from com.ning.compress.lzf.ChunkDecoder.decodeChunk.

Main decode from a stream. Decompressed bytes are placed in the outputBuffer, inputBuffer is a "scratch-area".

Parameters
is:InputStream

An input stream of LZF compressed bytes

inputBuffer:byte[]

A byte array used as a scratch area.

outputBuffer:byte[]

A byte array in which the result is returned

Returns:int

The number of bytes placed in the outputBuffer.

Implements abstract com.ning.compress.lzf.ChunkDecoder.skipOrDecodeChunk.

Returns:int

Doc from com.ning.compress.lzf.ChunkDecoder.skipOrDecodeChunk.

If positive number, number of bytes skipped; if -1, end-of-stream was reached; otherwise, amount of content decoded (using formula of returnValue = -(decodedAmount + 2))
