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.

Stores an Array of SubscriptionInfo objects. Each subscription contains a subtopic and a selector each of which can be null. A subscription with a non-null subtopic restricts the subscription to messages delivered with only that subtopic. If a subtopic is null, it uses the selector with no subtopic. If the selector and the subtopic is null, the subscription receives any messages targeted at the destination with no subtopic. The subtopic can contain a wildcard specification.
Before a call to the subscribe() method, this property
can be set with no side effects.
After the MultiTopicConsumer has subscribed to its destination, changing this
value has the side effect of updating the MultiTopicConsumer's subscription to
include any new subscriptions and remove any subscriptions you deleted from
the ArrayCollection.
The remote destination must understand the value of the selector expression.

This is a convenience method for adding a new subscription. It just creates a new SubscriptionInfo object and adds it to the subscriptions property. To call this method, you provide the subtopic and selector string for the new subscription. If the subtopic is null, the subscription applies to messages which do not have a subtopic set in the producer. If the selector string is null, all messages sent which match the subtopic string are received by this consumer.

Dispatched when a message is received by the Consumer.
The MESSAGE event type; dispatched upon receipt of a message.The value of this constant is "message".
The properties of the event object have the following values:
| Property | Value |
|---|---|
bubbles | false |
cancelable | false |
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. |
