forScan

protected CompressedChunkReader forScan()

Overrides:

releaseUnderlyingResources

public void releaseUnderlyingResources()

readChunk

public void readChunk(long position,
 ByteBuffer uncompressed)

Description copied from interface: ChunkReader

Read the chunk at the given position, attempting to fill the capacity of the given buffer. The filled buffer must be positioned at 0, with limit set at the size of the available data. The source may have requirements for the positioning and/or size of the buffer (e.g. chunk-aligned and chunk-sized). These must be satisfied by the caller.

close

public void close()

Specified by:

close in interface AutoCloseable

Specified by:

close in interface ReaderFileProxy

Overrides:

close in class AbstractReaderFileProxy
