      Modifier and Type Method Description
      java.nio.ByteBuffer acquire​(int size, boolean direct)
      Requests a ByteBuffer of the given size.
      void clearTracking()
      Clears the tracking data returned by getLeakedAcquires(), getLeakedReleases(), getLeakedResources().

      protected void leaked​(org.eclipse.jetty.util.LeakDetector.LeakInfo leakInfo)  
      void release​(java.nio.ByteBuffer buffer)
      Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.
      void remove​(java.nio.ByteBuffer buffer)
      Removes a ByteBuffer that was previously obtained with ByteBufferPool.acquire(int, boolean).

        public java.nio.ByteBuffer acquire​(int size,
                                   boolean direct)
        Description copied from interface: ByteBufferPool

        Requests a ByteBuffer of the given size.

        The returned buffer may have a bigger capacity than the size being requested but it will have the limit set to the given size.

        Specified by:
        acquire in interface ByteBufferPool
        Parameters:
        size - the size of the buffer
        direct - whether the buffer must be direct or not
        Returns:
        the requested buffer
