Unsupported Way to Force GC
There is a trick that will let you force the Flash player to carry out a full GC pass. This trick can be really handy for exploring Garbage Collection, and testing your applications during development,
but it should never be deployed in production code because it can wreak havoc with processor load. It is also officially unsupported, so you cannot rely on it to work in updated versions of the player.
To force an immediate GC mark/sweep, all you have to do is call connect() on two LocalConnections with the same name. This will throw an error, so you'll have to wrap it in a try/catch block.
Код:
try {
new LocalConnection().connect('foo');
new LocalConnection().connect('foo');
} catch (e:*) {}
// the GC will perform a full mark/sweep on the second call.
Again, this should only be used as a development aid. It should never be used in production code!
