Note legali | Informativa sulla privacy online

Property	Value
`acknowledgeMessage`	Utility property to get the message property from MessageEvent as an AcknowledgeMessage.
`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`.
`correlate`	The original Message correlated with this acknowledgement.
`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.

Property	Value
`bubbles`	false
`cancelable`	false
`channel`	The channel that generated this event.
`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`.
`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.
`reconnecting`	Indicates whether the channel that generated this event is reconnecting.
`rejected`	Indicates whether the channel that generated this event was rejected. This would be true in the event that the channel has been disconnected due to inactivity and should not attempt to failover or connect on an alternate channel.

Property	Value
`bubbles`	false
`cancelable`	false
`channel`	The channel that generated this event.
`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`.
`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.
`reconnecting`	Indicates whether the channel that generated this event is reconnecting.

Property	Value
`bubbles`	false
`cancelable`	false
`channel`	The Channel that generated this event.
`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`.
`faultCode`	Provides destination-specific details of the failure.
`faultDetail`	Provides access to the destination-specific reason for the failure.
`faultString`	Provides access to the underlying reason for the failure if the channel did not raise the failure itself.
`reconnecting`	Indicates whether the channel that generated this event is reconnecting.
`rootCause`	Provides access to the underlying reason for the failure if the channel did not raise the failure itself.
`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.

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`.

	`ackMsg:AcknowledgeMessage` — The AcknowledgMessage returned.

	`msg:IMessage` — The original sent message.

	`errMsg:ErrorMessage` — The ErrorMessage.

	`msg:IMessage` — The original sent message that caused this fault.

	`errMsg:ErrorMessage` — The Error Message.

	`msg:IMessage` — The message that caused the fault and should be resent once we have disconnected/connected causing re-authentication.

	`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.

	`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.

	`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".

Property	Value
`bubbles`	Determined by the constructor; defaults to false.
`cancelable`	Determined by the constructor; defaults to false.
`kind`	The kind of change; PropertyChangeEventKind.UPDATE or PropertyChangeEventKind.DELETE.
`oldValue`	The original property value.
`newValue`	The new property value, if any.
`property`	The property that changed.
`source`	The object that contains the property that changed.
`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`.
`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.
