| Method Summary | |
|---|---|
int |
decompress(byte[] b,
int off,
int len)
Fills specified buffer with uncompressed data. |
void |
end()
Closes the decompressor and discards any unprocessed input. |
boolean |
finished()
Returns true if the end of the compressed data output stream has been reached. |
boolean |
needsDictionary()
Returns true if a preset dictionary is needed for decompression. |
boolean |
needsInput()
Returns true if the input data buffer is empty and #setInput() should be called to provide more input. |
void |
reset()
Resets decompressor so that a new set of input data can be processed. |
void |
setDictionary(byte[] b,
