Like a Consumer, a MultiTopicConsumer subscribes to a destination with a single clientId and delivers messages to a single event handler. Unlike a Consumer it lets you register subscriptions for a list of subtopics and selector expressions at the same time from a single message handler. Where Consumer has subtopic and selector properties, this component has an addSubscription(subtopic, selector) method you use to add a new subscription to the existing set of subscriptions. Alternatively, you can populate the subscriptions property with a list of SubscriptionInfo instances that define the subscriptions for this destination.

Like the regular Consumer, the MultiTopicConsumer sends subscribe and unsubscribe messages which generate a MessageAckEvent or MessageFaultEvent depending upon whether the operation was successful or not. Once subscribed, a MultiTopicConsumer dispatches a MessageEvent for each message it receives.

`currentTarget`	The Object that defines the event listener that handles the event. For example, if you use `myButton.addEventListener()` to register an event listener, myButton is the value of the `currentTarget`.
`message`	The message associated with this event.
`target`	The Object that dispatched the event; it is not always the Object listening for the event. Use the `currentTarget` property to always access the Object listening for the event.

	`subtopic:String` (default = `null`) — The subtopic for the new subscription.

	`selector:String` (default = `null`) — The selector for the new subscription.

	`maxFrequency:uint` (default = `0`) — The maximum number of messages per second the Consumer wants to receive for the subscription. Note that this value overwrites the Consumer wide maxFrequency.
