Constructor

public function PollingChannel(id:String = null, uri:String = null)

Taalversie:

ActionScript 3.0

Productversies:

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

Runtimeversies:

Flash Player 9, AIR 1.1

Creates a new PollingChannel instance with the specified id. Once a PollingChannel is connected and begins polling, it will issue a poll request once every three seconds by default.

Note: The PollingChannel type should not be constructed directly. Instead create instances of protocol specific subclasses such as HTTPChannel or AMFChannel that extend it.

Parameters

	`id:String` (default = `null`) — The id of this Channel.

	`uri:String` (default = `null`) — The uri for this Channel.

Methodedetails

disablePolling

()

methode

public function disablePolling():void

Taalversie:

ActionScript 3.0

Productversies:

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

Runtimeversies:

Flash Player 9, AIR 1.1

Disables polling based on the number of times enablePolling() and disablePolling() have been invoked. If the net result is to disable polling the channel stops polling.

Invoked automatically based upon subscribing or unsubscribing from a remote destination over a PollingChannel.

enablePolling

()

methode

public function enablePolling():void

Taalversie:

ActionScript 3.0

Productversies:

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

Runtimeversies:

Flash Player 9, AIR 1.1

Enables polling based on the number of times enablePolling() and disablePolling() have been invoked. If the net result is to enable polling the channel will poll the server on behalf of connected MessageAgents.

Invoked automatically based upon subscribing or unsubscribing from a remote destination over a PollingChannel.

poll

()

methode

public function poll():void

Taalversie:

ActionScript 3.0

Productversies:

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

Runtimeversies:

Flash Player 9, AIR 1.1

Initiates a poll operation if there are consumers subscribed to this channel, and polling is enabled for this channel. Note that this method will not start a new poll if one is currently in progress.

send

()

methode

override public function send(agent:MessageAgent, message:IMessage):void

Taalversie:

ActionScript 3.0

Productversies:

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

Runtimeversies:

Flash Player 9, AIR 1.1

Sends the specified message to its target destination. Subclasses must override the internalSend() method to perform the actual send. PollingChannel will wrap outbound messages in poll requests if a poll is not currently outstanding.

Parameters

	`agent:MessageAgent` — The MessageAgent that is sending the message.

	`message:IMessage` — The Message to send.

Gegenereerde uitzondering

InvalidDestinationError — If neither the MessageAgent nor the message specify a destination.
