Property Detail

authenticated

property

authenticated:Boolean [read-only]

Indicates if this MessageAgent is using an authenticated connection to its destination.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Implementation
public function get authenticated():Boolean

channelSet

property

channelSet:ChannelSet

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the ChannelSet used by the MessageAgent. The ChannelSet can be manually constructed and assigned, or it will be dynamically initialized to use the configured Channels for the destination for this MessageAgent.

ActionScript 3.0

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the client id for the MessageAgent. MessageAgents are assigned their client id by the remote destination and this value is used to route messages from the remote destination to the proper MessageAgent.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Implementation
public function get clientId():String

connected

property

connected:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Indicates whether this MessageAgent is currently connected to its destination via its ChannelSet. The propertyChange event is dispatched when this property changes.

This property can be used as the source for data binding. When this property is modified, it dispatches the propertyChange event.

Implementation
public function get connected():Boolean

destination

property

destination:String

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the destination for the MessageAgent. Changing the destination will disconnect the MessageAgent if it is currently connected.

Runtime Versions:

Flash Player 9, AIR 1.1

Called after the implementing object has been created and all properties specified on the tag have been assigned.

Parameters

	`document:Object` — MXML document that created this object.

	`id:String` — id used by the document to refer to this object. If the object is a deep property on the document, id is null.

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Sends a Message from the MessageAgent to its destination using the agent's ChannelSet. MessageAgent subclasses must use this method to send their messages.

Parameters

	`message:IMessage` — The message to send.

	`waitForClientId:Boolean` (default = `true`) — If true the message may be queued until a clientId has been assigned to the agent. In general this is the desired behavior. For special behavior (automatic reconnect and resubscribe) the agent may pass false to override the default queuing behavior.

Throws

InvalidDestinationError — If no destination is set.

logout

()

method

public function logout():void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, Adobe Digital Enterprise Platform Data Services for Java EE 3

Runtime Versions:

Flash Player 9, AIR 1.1

Logs the MessageAgent out from its remote destination. Logging out of a destination applies to everything connected using the same ChannelSet as specified in the server configuration. 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.
