because TeeSplit can't remove a pipefitting of our choosing I extended it
and added in this method:
public function removePipeFitting(inpipe:IPipeFitting):IPipeFitting {
var outputsac:ArrayCollection = new ArrayCollection(outputs);
if (outputsac.getItemIndex(inpipe) >= 0) {
return outputsac.removeItemAt(outputsac.getItemIndex(inpipe)) as IPipeFitting;
}
return null;
}
in a PipeAwareModule you can add a reference to the pipes connecting to it.
private var _cachedPipes:ArrayCollection = new ArrayCollection([]);
/**
* used to remove pipes at the shell's side of the junction
*
* @param pipefitting we are going to call disconnect on this pipefitting
* @param output
*
*/
public function cacheFitting(pipefitting:IPipeFitting, output:IPipeFitting):void {
_cachedPipes.addItem({pipefitting:pipefitting, output:output});
}
/**
* goes through the arraycollection disconnecting the pipefitting from output
*
*/
public function removepipes():void {
for each (var pipefittings:Object in _cachedPipes) {
if (pipefittings.pipefitting is TeeSplitImproved) {
(pipefittings.pipefitting as TeeSplitImproved).removePipeFitting(pipefittings.output);
}
else {
(pipefittings.pipefitting as IPipeFitting).disconnect();
}
}
_cachedPipes.removeAll();
}
if your module has a unload method you'd want to:
1] call facade.removeMediator on every mediator (in the junction mediator's onRemove method do junction.removePipe on all pipefittings attached to that junction), facade.removeProxy, ..etc
2] call the removepipes() to remove incoming pipes, then
3] call facade.removeCore to get rid of all the core actors.
