decodeChunk
public final int decodeChunk(java.io.InputStream is, byte[] inputBuffer, byte[] outputBuffer) throws java.io.IOException
Description copied from class:ChunkDecoder
Main decode from a stream. Decompressed bytes are placed in the outputBuffer, inputBuffer is a "scratch-area".- Specified by:
decodeChunk
in classChunkDecoder
- Parameters:
is
- An input stream of LZF compressed bytesinputBuffer
- A byte array used as a scratch area.outputBuffer
- A byte array in which the result is returned- Returns:
- The number of bytes placed in the outputBuffer.
- Throws:
java.io.IOException
-
decodeChunk
public final void decodeChunk(byte[] in, int inPos, byte[] out, int outPos, int outEnd) throws LZFException
Description copied from class:ChunkDecoder
Main decode method for individual chunks.- Specified by:
decodeChunk
in classChunkDecoder
- Throws:
LZFException
-
skipOrDecodeChunk
public int skipOrDecodeChunk(java.io.InputStream is, byte[] inputBuffer, byte[] outputBuffer, long maxToSkip) throws java.io.IOException
- Specified by:
skipOrDecodeChunk
in classChunkDecoder
- Returns:
- 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)
) - Throws:
java.io.IOException
-
