Property Detail

authenticated

property

authenticated:Boolean [read-only]

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Indicates whether the ChannelSet has an underlying Channel that successfully authenticated with its endpoint.

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

channelIds

property

channelIds:Array [read-only]

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

The ids of the Channels used by the ChannelSet.

Implementation
public function get channelIds():Array

channels

property

channels:Array

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the Channels in the ChannelSet. This property may be used to assign a set of channels at once or channels may be added directly to the ChannelSet via addChannel() individually. If this ChannelSet is configured automatically the individual channels are created lazily and added to this property as needed.

Implementation
public function get channels():Array
public function set channels(value:Array):void

Throws

IllegalOperationError — If the ChannelSet is configured, assigning to this property is not allowed.

clustered

property

clustered:Boolean

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Indicates whether the ChannelSet targets a clustered destination. If true, upon a successful connection the ChannelSet will query the destination for all clustered endpoints for its Channels and will assign failoverURIs to them. Channel ids are used to assign failoverURIs to the proper Channel instances so this requires that all Channels in the ChannelSet have non-null ids and an Error will be thrown when this property is set to true if this is not the case. If the ChannelSet is not using url load balancing on the client this property should not be set to true.

Implementation
public function get clustered():Boolean
public function set clustered(value:Boolean):void

connected

property

connected:Boolean [read-only]

Indicates whether the ChannelSet is connected.

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

currentChannel

property

currentChannel:Channel [read-only]

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Returns the current Channel for the ChannelSet.

Implementation
public function get currentChannel():Channel

heartbeatInterval

property

heartbeatInterval:int

The number of milliseconds between heartbeats sent to the remote host while this ChannelSet is actively connected but idle. Any outbound message traffic will delay heartbeats temporarily, with this number of milliseconds elapsing after the last sent message before the next heartbeat is issued.

This property is useful for applications that connect to a remote host to received pushed updates and are not actively sending any messages, but still wish to be notified of a dropped connection even when the networking layer fails to provide such notification directly. By issuing periodic heartbeats the client can force the networking layer to report a timeout if the underlying connection has dropped without notification and the application can respond to the disconnect appropriately.

Any non-positive value disables heartbeats to the remote host. The default value is 0 indicating that heartbeats are disabled. If the application sets this value it should prefer a longer rather than shorter interval, to avoid placing unnecessary load on the remote host. As an illustrative example, low-level TCP socket keep-alives generally default to an interval of 2 hours. That is a longer interval than most applications that enable heartbeats will likely want to use, but it serves as a clear precedent to prefer a longer interval over a shorter interval.

If the currently connected underlying Channel issues poll requests to the remote host, heartbeats are suppressed because the periodic poll requests effectively take their place.

Implementation
public function get heartbeatInterval():int
public function set heartbeatInterval(value:int):void

initialDestinationId

property

initialDestinationId:String

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the initial destination this ChannelSet is used to access. When the clustered property is true, this value is used to request available failover URIs for the configured channels for the destination.

Implementation
public function get initialDestinationId():String
public function set initialDestinationId(value:String):void

messageAgents

property

messageAgents:Array [read-only]

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Provides access to the set of MessageAgents that use this ChannelSet.

Implementation
public function get messageAgents():Array

Constructor Detail

ChannelSet

()

Constructor

public function ChannelSet(channelIds:Array = null, clusteredWithURLLoadBalancing:Boolean = false)

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Constructs a ChannelSet. If the channelIds argument is provided, the ChannelSet will use automatically configured Channels obtained via ServerConfig.getChannel() to reach a destination. Attempting to manually assign Channels to a ChannelSet that uses configured Channels is not allowed.

If the channelIds argument is not provided or is null, Channels must be manually created and added to the ChannelSet in order to connect and send messages.

If the ChannelSet is clustered using url-load-balancing (where each server declares a unique RTMP or HTTP URL and the client fails over from one URL to the next), the first time that a Channel in the ChannelSet successfully connects the ChannelSet will automatically make a request for all of the endpoints across the cluster for all member Channels and will assign these failover URLs to each respective Channel. This allows Channels in the ChannelSet to failover individually, and when failover options for a specific Channel are exhausted the ChannelSet will advance to the next Channel in the set to attempt to reconnect.

Regardless of clustering, if a Channel cannot connect or looses connectivity, the ChannelSet will advance to its next available Channel and attempt to reconnect. This allows the ChannelSet to hunt through Channels that use different protocols, ports, etc., in search of one that can connect to its endpoint successfully.

Parameters

	`channelIds:Array` (default = `null`) — The ids of configured Channels obtained from ServerConfig for this ChannelSet to use. If null, Channels must be manually added to the ChannelSet.

	`clusteredWithURLLoadBalancing:Boolean` (default = `false`) — True if the Channels in the ChannelSet are clustered using url load balancing.

Method Detail

addChannel

()

method

public function addChannel(channel:Channel):void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Adds a Channel to the ChannelSet. A Channel with a null id cannot be added to the ChannelSet if the ChannelSet targets a clustered destination.

Parameters

channel:Channel — The Channel to add.

Throws

IllegalOperationError — If the ChannelSet is configured, adding a Channel is not supported. This error is also thrown if the ChannelSet's clustered property is true but the Channel has a null id.

channelConnectHandler

()

method

public function channelConnectHandler(event:ChannelEvent):void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Flash Player 9, AIR 1.1

Handles a DISCONNECT ChannelEvent and redispatches the event.

Parameters

event:ChannelEvent — The ChannelEvent.

channelFaultHandler

()

method

public function channelFaultHandler(event:ChannelFaultEvent):void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Handles a ChannelFaultEvent and redispatches the event.

Parameters

event:ChannelFaultEvent — The ChannelFaultEvent.

connect

()

method

public function connect(agent:MessageAgent):void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Connects a MessageAgent to the ChannelSet. Once connected, the agent can use the ChannelSet to send messages.

Parameters

agent:MessageAgent — The MessageAgent to connect.

disconnect

()

method

public function disconnect(agent:MessageAgent):void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Disconnects a specific MessageAgent from the ChannelSet. If this is the last MessageAgent using the ChannelSet and the current Channel in the set is connected, the Channel will physically disconnect from the server.

Parameters

agent:MessageAgent — The MessageAgent to disconnect.

disconnectAll

()

method

public function disconnectAll():void

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Disconnects all associated MessageAgents and disconnects any underlying Channel that is connected. Unlike disconnect(MessageAgent) which is invoked by the disconnect implementations of specific service components, this method provides a single, convenient point to shut down connectivity between the client and server.

login

()

method

public function login(username:String, password:String, charset:String = null):mx.rpc:AsyncToken

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Authenticates the ChannelSet with the server using the provided credentials. Unlike other operations on Channels and the ChannelSet, this operation returns an AsyncToken that client code may add a responder to in order to handle success or failure directly. If the ChannelSet is not connected to the server when this method is invoked it will trigger a connect attempt, and if successful, send the login command to the server. Only one login or logout operation may be pending at a time and overlapping calls will generate an IllegalOperationError. Invoking login when the ChannelSet is already authenticated will generate also generate an IllegalOperationError.

Parameters

	`username:String` — The username.

	`password:String` — The password.

	`charset:String` (default = `null`) — The character set encoding to use while encoding the credentials. The default is null, which implies the legacy charset of ISO-Latin-1. The only other supported charset is "UTF-8".

Returns

mx.rpc:AsyncToken — Returns a token that client code may add a responder to in order to handle success or failure directly.

Throws

IllegalOperationError — in two situations; if the ChannelSet is already authenticated, or if a login or logout operation is currently in progress.

logout

()

method

public function logout(agent:MessageAgent = null):mx.rpc:AsyncToken

Logs the ChannelSet out from the server. Unlike other operations on Channels and the ChannelSet, this operation returns an AsyncToken that client code may add a responder to in order to handle success or failure directly. If logout is successful any credentials that have been cached for use in automatic reconnects are cleared for the ChannelSet and its Channels and their authenticated state is set to false. If the ChannelSet is not connected to the server when this method is invoked it will trigger a connect attempt, and if successful, send a logout command to the server.

The MessageAgent argument is present to support legacy logout behavior and client code that invokes this method should not pass a MessageAgent reference. Just invoke logout() passing no arguments.

This method is also invoked by service components from their logout() methods, and these components pass a MessageAgent reference to this method when they logout. The presence of this argument is the trigger to execute legacy logout behavior that differs from the new behavior described above. Legacy behavior only sends a logout request to the server if the client is connected and authenticated. If these conditions are not met the legacy behavior for this method is to do nothing other than clear any credentials that have been cached for use in automatic reconnects.

Parameters

agent:MessageAgent (default = null) — Legacy argument. The MessageAgent that is initiating the logout.

Returns

mx.rpc:AsyncToken — Returns a token that client code may add a responder to in order to handle success or failure directly.

Throws

IllegalOperationError — if a login or logout operation is currently in progress.

messageHandler

()

method

protected function messageHandler(event:MessageEvent):void

Redispatches message events from the currently connected Channel.

Parameters

event:MessageEvent — The MessageEvent from the Channel.

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Flash Player 9, AIR 1.1

Removes a Channel from the ChannelSet. If the Channel to remove is currently connected and being used by the ChannelSet, it is disconnected as well as removed.

Parameters

channel:Channel — The Channel to remove.

Throws

IllegalOperationError — If the ChannelSet is configured, removing a Channel is not supported.

send

()

method

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

Language Version:

ActionScript 3.0

Product Versions:

BlazeDS 4, LiveCycle Data Services 3

Runtime Versions:

Sends a message from a MessageAgent over the currently connected Channel.

Parameters

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

	`message:IMessage` — The Message to send.

Throws
