Field Detail

• SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS

  public static final String SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS

  System property that is checked to see if recycled buffers (see BufferRecycler) should be tracked, for purpose of forcing release of all such buffers, typically during major classloading.

  Since:

  2.9.6

  Constant Field Values

• _recyclerRef

  protected static final ThreadLocal<SoftReference<BufferRecycler>> _recyclerRef

  This ThreadLocal contains a SoftReference to a BufferRecycler used to provide a low-cost buffer recycling between reader and writer instances.

Constructor Detail

• BufferRecyclers

  public BufferRecyclers()

Method Detail

• getBufferRecycler

  public static BufferRecycler getBufferRecycler()

  Main accessor to call for accessing possibly recycled BufferRecycler instance.

  Returns:

  BufferRecycler to use

• releaseBuffers

  public static int releaseBuffers()

  Specialized method that will release all recycled BufferRecycler if (and only if) recycler tracking has been enabled (see SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS). This method is usually called on shutdown of the container like Application Server to ensure that no references are reachable via ThreadLocals as this may cause unintentional retention of sizable amounts of memory. It may also be called regularly if GC for some reason does not clear up SoftReferences aggressively enough.

  Returns:

  Number of buffers released, if tracking enabled (zero or more); -1 if tracking not enabled.

  Since:

  2.9.6
