Methods
getDebugObject()
Returns the debugger object if the debug service is active.
nsISupports getDebugObject();
Parameters
None.
Return value
If jsdIDebuggerService is active and the listener is implemented in JS, this returns the listener as a jsdIValue. Otherwise null. This is the method you should use if you want to get access to the actual listener, but the debugger service must be already active, which significantly slows down script execution. Accordingly, this should probably only be used by real debuggers. This approach is necessary because event listeners added with addEventListener won't necessarily be nsIEventListeners; the DOM code will fix up ordinary JavaScript functions to act as listeners.
toSource()
Tries to serialize the event listener to a string.
AString toSource();
Parameters
None.
Return value
Returns a string describing the event listener, or null if serialization isn't possible (for example, if the listener was written in C++).
Remarks
nsIEventListenerInfo was introduced with bug 448602.
