uk.ac.gla.terrier.compression
Class MemorySBOS

java.lang.Object
  uk.ac.gla.terrier.compression.BitOutputStream
      uk.ac.gla.terrier.compression.BitByteOutputStream
          uk.ac.gla.terrier.compression.MemorySBOS

All Implemented Interfaces:

java.io.Closeable, BitOut

public class MemorySBOS
extends BitByteOutputStream

This class extends the BitByteOutputStream, so it provides the compression writting functions, but uses a MemoryOutputStream as an underlying OutputStream, so it is needed to be flushed to disk separately. It uses BitByteOutputStream and not BitOutputStream because the MemoryOutputStream class has already its own buffer (to keep everything in memory), and extra buffering is inadequate.
