- - ### Method Detail

    - #### getRegion

          Region<K,V> getRegion()

      Returns the `Region` associated with this AsyncEvent
      Returns:
        the `Region` associated with this AsyncEvent OR null if `Region` not found (e.g. this can happen if it is destroyed).

    - #### getOperation

          Operation getOperation()

      Returns the `Operation` that triggered this event.
      Returns:
        the `Operation` that triggered this event

    - #### getCallbackArgument

          Object getCallbackArgument()

      Returns the callbackArgument associated with this event.
      Returns:
        the callbackArgument associated with this event

    - #### getKey

          K getKey()

      Returns the key associated with this event.
      Returns:
        the key associated with this event

    - #### getDeserializedValue

          V getDeserializedValue()

      Returns the deserialized value associated with this event.
      Returns:
        the deserialized value associated with this event
      Throws:
        `IllegalStateException` - may be thrown if the event's value was stored off-heap and `AsyncEventListener.processEvents(java.util.List)` has already returned.

    - #### getSerializedValue

          byte[] getSerializedValue()

      Returns the serialized form of the value associated with this event.
      Returns:
        the serialized form of the value associated with this event
      Throws:
        `IllegalStateException` - may be thrown if the event's value was stored off-heap and `AsyncEventListener.processEvents(java.util.List)` has already returned.
