Class BufferRecyclers

  • @Deprecated
public class BufferRecyclers
extends java.lang.Object
    Deprecated.
    Since 2.16 recycling aspects are handled via RecyclerPool.
    Helper entity used to control access to simple buffer recycling scheme used for some encoding, decoding tasks.
    Since:
    2.9.2
    See Also:
    BufferRecycler

      • SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS

        public static final java.lang.String SYSTEM_PROPERTY_TRACK_REUSABLE_BUFFERS
        Deprecated.
        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 garbage-collection.
        Since:
        2.9.6

        public BufferRecyclers()
        Deprecated.

    • Method Detail

      • getBufferRecycler

        @Deprecated
public static BufferRecycler getBufferRecycler()
        Deprecated.
        Since 2.16 should use RecyclerPool abstraction instead of calling static methods of this class
        Main accessor to call for accessing possibly recycled BufferRecycler instance.
        Returns:
        BufferRecycler to use

      • releaseBuffers

        public static int releaseBuffers()
        Deprecated.
        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
