How To Link "extent-change" And "update-end" Events In Dojo?

In ArcGIS JS API I need to trigger a method of my class when the processing after an extent change is complete. I didn't find any special event for this. extent-change triggers too

Solution 1:

I solved this issue by flattening the event listeners. First, I made a flag _reloadFlag, initialized in the constructor as false and then changed to true whenever I want to call _bar, like in _foo. _bar now starts with a test of _reloadFlag either setting it to false or returning nothing. The event listeners now look like this:

this.events.push(on(this.map, "extent-change", lang.hitch(this, this._foo)));
this.events.push(on(this.map, "update-end", lang.hitch(this, this._bar)));
