Connected Property

Triggers a connection or disconnection.

Syntax

 stomp.getConnected([callback])
 stomp.setConnected( connected, [callback])

Default Value

FALSE

Callback

The 'callback' parameter specifies a function which will be called when the operation completes (or an error is encountered). If the 'callback' parameter is not specified, then the method will block and will not return until the operation completes (or an error is encountered).

The callback for the getConnected([callback]) method is defined as:

function(err, data){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'data' is the value returned by the method.

The callback for the setConnected([callback]) method is defined as:

function(err){ }

'err' is the error that occurred. If there was no error, then 'err' is 'null'.

'err' has 2 properties which hold detailed information:

err.code
err.message

Remarks

This property triggers a connection or disconnection. Setting this property to True makes the class attempt to connect to the host identified by the RemoteHost property. If successful, after the connection is achieved the value of the property changes to True and the Connected event is fired.

Setting this property to False closes the connection.

When connecting to a STOMP server, the class sends information from the following properties, if populated:

In addition to the above properties, the following configuration settings can be set before connecting (though in most cases this is not necessary):

  • SupportedVersions: Controls which STOMP versions the class advertises support for.
  • VirtualHost: Controls the virtual host to connect to. If left empty (default), the value from RemoteHost is used.

This property is not available at design time.

Data Type
