it depends on references, not whether you use or not.
so for example, if the code is like this:
MainClass.mxml
<foo:MainClass>
<foo:SubClass id="bl"/>
</foo:MainClass>
SubClass.mxml
<foo:SubClass>
<foo:SubClass2a id='bla'/>
</foo:SubClass>
they will live forever. But if you load them dynamically, it depends on
where you keep the reference.
If the reference is lost, it 'may' get removed by garbage collector.
(can never be sure because by the nature you cannot control garbage
collector).
So it depends what you mean by call (calling a function or creating) and
also the creation policy of the container class.
One more thing to pay attention on memory manager is be careful with the
event listener. For example
When you write:
A.addEventListener("fooEvent",B.onFooEvent);
a reference from A to B is created, so there is nothing to keep A in the
memory.
If you pay attention on creation policy and addEventListener, you'll be
fine.
