    • allocateNewBuffer

      private ByteBuffer allocateNewBuffer(int _size)
      Allocate and return a new direct ByteBuffer.

    • getBufferSupport

      protected DirectByteBuffer getBufferSupport(byte _allocator, int _length)
      Retrieve a buffer from the buffer pool of size at least length, and no larger than DirectByteBufferPool.MAX_SIZE
      Specified by:
      getBufferSupport in class DirectByteBufferPool

    • getBufferHelper

      private DirectByteBuffer getBufferHelper(byte _allocator, int _length)
      Retrieve an appropriate buffer from the free pool, or create a new one if the pool is empty.

    • returnBufferSupport

      protected void returnBufferSupport(DirectByteBuffer ddb)
      Return the given buffer to the appropriate pool.
      Specified by:
      returnBufferSupport in class DirectByteBufferPool

    • clearBufferPools
