    Modifier and Type
    Method
    Description
    ByteBuffer
    acquire(int size, boolean direct)
    Requests a ByteBuffer of the given size.
    RetainableByteBufferPool
    asRetainableByteBufferPool()
    Get this pool as a RetainableByteBufferPool, which supports reference counting of the buffers and possibly a more efficient lookup mechanism based on the Pool class.
    void
    clearTracking()
    Clears the tracking data returned by getLeakedAcquires(), getLeakedReleases(), getLeakedResources().

    void
    release(ByteBuffer buffer)
    Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.
    void
    remove(ByteBuffer buffer)
    Removes a ByteBuffer that was previously obtained with ByteBufferPool.acquire(int, boolean).

  • Method Details

    • asRetainableByteBufferPool

      public RetainableByteBufferPool asRetainableByteBufferPool()
      Description copied from interface: ByteBufferPool
      Get this pool as a RetainableByteBufferPool, which supports reference counting of the buffers and possibly a more efficient lookup mechanism based on the Pool class.
      Specified by:
      asRetainableByteBufferPool in interface ByteBufferPool
      Returns:
      This pool as a RetainableByteBufferPool. The same instance is always returned by multiple calls to this method.

    • acquire

      public 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.

      Specified by:
      acquire in interface ByteBufferPool
      Parameters:
      size - the size of the buffer
      direct - whether the buffer must be direct or not
      Returns:
      a buffer with at least the requested capacity, with position and limit set to 0.

    • release

      public void release(ByteBuffer buffer)
      Description copied from interface: ByteBufferPool

      Returns a ByteBuffer, usually obtained with ByteBufferPool.acquire(int, boolean) (but not necessarily), making it available for recycling and reuse.

      Specified by:
      release in interface ByteBufferPool
      Parameters:
      buffer - the buffer to return
      See Also:

    • remove

      public void remove(ByteBuffer buffer)
      Description copied from interface: ByteBufferPool

      Removes a ByteBuffer that was previously obtained with ByteBufferPool.acquire(int, boolean).

      The buffer will not be available for further reuse.

      Specified by:
      remove in interface ByteBufferPool
      Parameters:
      buffer - the buffer to remove
      See Also:

    • clearTracking

      @ManagedAttribute("Clears the tracking data") public void clearTracking()
      Clears the tracking data returned by getLeakedAcquires(), getLeakedReleases(), getLeakedResources().

    • getLeakedAcquires

      @ManagedAttribute("The number of acquires that produced a leak") public long getLeakedAcquires()
      Returns:
      count of ByteBufferPool.acquire() calls that detected a leak

    • getLeakedReleases

      @ManagedAttribute("The number of releases that produced a leak") public long getLeakedReleases()
      Returns:
      count of ByteBufferPool.release() calls that detected a leak

    • getLeakedRemoves

      @ManagedAttribute("The number of removes that produced a leak") public long getLeakedRemoves()
      Returns:
      count of ByteBufferPool.remove() calls that detected a leak

    • getLeakedResources

      @ManagedAttribute("The number of resources that were leaked") public long getLeakedResources()
      Returns:
      count of resources that were acquired but not released
