Class RetainableByteBuffer

  • All Implemented Interfaces:

    public class RetainableByteBuffer
    extends java.lang.Object
    implements Retainable

    A pooled ByteBuffer which maintains a reference count that is incremented with retain() and decremented with release(). The buffer is released to the pool when release() is called one more time than retain().

    A RetainableByteBuffer can either be:

    Calling release() on a out of pool and retained instance does not re-pool it while that re-pools it on a out of pool but not retained instance.
