The MessageAgent class provides the basic low-level functionality common to message handling for a destination.

Note: For advanced use only. Use this class for creating custom message agents like the existing Producer and Consumer classes.

MXML 語法

All message agent classes, including the Producer and Consumer classes, extend MessageAgent and inherit the following tag attributes:

   <mx:tagname

    Properties
    channelSet="No default."
    clientId="No default."
    connected="false"
    destination="No default."
    requestTimeout="-1"
    subtopic="No default."
 
 
   Events
    acknowledge="No default."
    channelConnect="No default."
    channelDisconnect="No default."
    channelFault="No default."
    fault="No default."
    propertyChange="No default."

For example, if several DataService components are connected over an RTMP channel and logout() is invoked on one of them, all other client components that are connected using the same ChannelSet are also logged out.

Note: Adobe recommends that you use the mx.messaging.ChannelSet.logout() method rather than this method.
