Re: [flexcoders] AS3 class constructors can't be private? Abstract classes?

I was supposing that don't have private constructors was due to the alpha state of the player, but it seems like is something deliberated. IMHO, I don't agree with this design languaje issue cause patterns like singletons are widely used and people expect to use in the standard way. I don't want to argue but would like the guys behind this responsability to think about it a bit and think about what their users expect to find when deal with the languaje. Thanks for listening :)

so even if i create a private class that is only accecible in that package (and then on package level declare a accesor for it) the only way i can be certain that class will only be created once is by having nothing else in that package. this does not seem right.

You have to simulate private constructors by having the constructor take a class that is inaccessible to other classes (namely putting that class in the same file as the singleton outside of the package block).  Unfortunately I believe the rule is that the constructor of the class has to have the same visibility as the class itself.  So public classes need public constructors, internal classes get internal constructors, etc.

abstract classes i am not expecting, private constructers i certainly hope for

Hi,

I was trying to migrate some classes from AS2 to AS3 and notice that can't mark the class constructor as private. Is that correct or there's a workaround? if not have plans to implement private constructors.

and abstract classes?

Thanks in advance.
