decompress
public void decompress(DataInput in, int originalLength, int offset, int length, BytesRef bytes) throws IOException Description copied from class:Decompressor
Decompress bytes that were stored between offsetsoffset
andoffset+length
in the original stream from the compressed streamin
tobytes
. After returning, the length ofbytes
(bytes.length
) must be equal tolength
. Implementations of this method are free to resizebytes
depending on their needs.- Specified by:
decompress
in classDecompressor
- Parameters:
in
- the input that stores the compressed streamoriginalLength
- the length of the original data (before compression)offset
- bytes before this offset do not need to be decompressedlength
- bytes afteroffset+length
do not need to be decompressedbytes
- aBytesRef
where to store the decompressed data- Throws:
IOException
