Class BackedCompressedByteBuffer

java.lang.Object
  org.galagosearch.core.index.BackedCompressedByteBuffer

public class BackedCompressedByteBuffer
extends java.lang.Object

A BackedCompressedByteBuffer is like a CompressedByteBuffer, but it can overflow into disk storage if necessary. Unlike a CompressedByteBuffer, there's no getBytes() method since that wouldn't makes sense if all the data is on disk.
