SubscribeTo Method

Use this method to subscribe to another entity's presence.

Syntax

xmpp.subscribeTo(jabberId, [callback])

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 this 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 method will send a request for a subscription to JabberId's presence. If the entity allows the subscription, a new item will be stored in the buddy list with the appropriate subscription type. Otherwise, no change will take place.
