public int decrementReferenceCount(){
  return m_referenceCount.decrementAndGet();
}

public int decrementReferenceCount ( ) { return m_referenceCount . decrementAndGet ( ) ; }
although public , it is designed to be used by the writecacheservice with a memoizer pattern to support concurrent reads to read cache buffers . called when a reference is released . the return value should be tested and if zero the cache should be returned to the clean list .
