A Consumer subscribes to a destination to receive messages. Consumers send subscribe and unsubscribe messages which generate a MessageAckEvent or MessageFaultEvent depending upon whether the operation was successful or not. Once subscribed, a Consumer dispatches a MessageEvent for each message it receives. Consumers provide the ability to filter messages using a selector. These selectors must be understood by the destination.

The <mx:Consumer> tag inherits all the tag attributes of its superclass, and adds the following tag attributes:

   <mx:Consumer
    Properties
    resubscribeAttempts="5"

    selector="No default."
    timestamp="No default."

The selector for the Consumer. This is an expression that is passed to the destination which uses it to filter the messages delivered to the Consumer.

Before a call to the subscribe() method, this property can be set with no side effects. After the Consumer has subscribed to its destination, changing this value has the side effect of updating the Consumer's subscription to use the new selector expression immediately.

The remote destination must understand the value of the selector expression.

이 속성은 데이터 바인딩에 대한 소스로 사용할 수 있습니다. 이 속성을 수정하면 propertyChange 이벤트를 전달합니다.

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.
