        Region<K,​V> getRegion()

      • getCallbackArgument

        java.lang.Object getCallbackArgument()
        Returns the callbackArgument passed to the method that generated this event. Provided primarily in case this object or region has already been destroyed. See the Region interface methods that take a callbackArgument parameter. Only fields on the key should be used when creating the routing object.
        Returns:
        the callbackArgument associated with this event. null is returned if the callback argument is not propagated to the event. This happens for events given to TransactionListener and to CacheListener on the remote side of a transaction commit.

      • isCallbackArgumentAvailable

        boolean isCallbackArgumentAvailable()
        Returns true if the callback argument is "available". Not available means that the callback argument may have existed but it could not be obtained. Note that getCallbackArgument() will return null when this method returns false.
        Returns:
        the callback argument is available
