- - ### Method Detail

    - #### getId

          java.lang.String getId()

      Returns the ID of the AsyncEventQueue.

    - #### getOverflowDiskStoreName

          java.lang.String getOverflowDiskStoreName()

      Returns the name of the disk store that is used for persistence.

    - #### getMaximumQueueMemory

          int getMaximumQueueMemory()

      Returns the maximum memory after which the data needs to be overflowed to disk.

    - #### getBatchSize

          int getBatchSize()

      Returns the size of a batch that gets delivered over the AsyncEventQueue.

    - #### getBatchTimeInterval

          long getBatchTimeInterval()

      Returns the interval between transmissions by the AsyncEventQueue.

    - #### isBatchConflationEnabled

          boolean isBatchConflationEnabled()

      Returns whether batch conflation for the AsyncEventQueue is enabled
      Returns:
        True if batch conflation is enabled, false otherwise.

    - #### isPersistent

          boolean isPersistent()

      Returns whether the AsyncEventQueue is configured to be persistent or non-persistent.
      Returns:
        True if the queue is persistent, false otherwise.

    - #### isPrimary

          boolean isPrimary()

      Returns whether the queue is primary or secondary. Events get delivered only by the primary queue. If the primary queue goes down then the secondary queue first becomes primary and then starts delivering the events.
      Returns:
        True if this is the primary queue, false otherwise.

    - #### getDispatcherThreads

          int getDispatcherThreads()

      Returns the number of dispatcher threads working for this `AsyncEventQueue`.

    - #### getOrderPolicy

          java.lang.String getOrderPolicy()

      Returns the order policy followed while dispatching the events to remote distributed system. Order policy is only relevant when the number of dispatcher threads is greater than one.

    - #### isDiskSynchronous

          boolean isDiskSynchronous()

      Returns whether the isDiskSynchronous property is set for this AsyncEventQueue.
      Returns:
        True if the property is set, false otherwise.

    - #### isParallel

          boolean isParallel()

      Returns whether the isParallel property is set for this AsyncEventQueue.
      Returns:
        True if the property is set, false otherwise.

    - #### getAsyncEventListener

          java.lang.String getAsyncEventListener()

      Returns the class name of the AsyncEventListener that is attached to the queue.

    - #### getEventQueueSize

          int getEventQueueSize()

      Returns the Size of the event queue
      Returns:
        integer

    - #### getLRUEvictionsRate

          float getLRUEvictionsRate()

      Returns the rate of LRU evictions per second by this Sender.

    - #### getEntriesOverflowedToDisk

          long getEntriesOverflowedToDisk()

      Returns the number of entries overflowed to disk for this Sender.

    - #### getBytesOverflowedToDisk

          long getBytesOverflowedToDisk()

      Returns the number of bytes overflowed to disk for this Sender.
