That way, I still have the instance.

There is one technique you can use to do the true singleton:

But its a little overkill.

Usually, the technique mentioned here is good enough.

Just be careful not to use code like that in frameworks etc.

People can and will use your code badly.

Sorry it should say something like:

MySingletonClass is a singleton and can only be accessed through MySingletonClass.getInstance()

At the moment I’m creating all my singletons accessable using the same approach as Flex 2.0 uses, so instead of getInstance() i used a getter and the name of the class.

Application.application
SystemManager.systemManager
MySingletonClass.mySingletonClass

Good stuff though =)

//In Singleton.as
package my.dummy.package
{
public class Singleton
{
public function Singleton(theClass:CreationClass){ … }

public function getInstance():void
{
_instance = new Singleton(new CreationClass());
}
}
}
class CreationClass {} //Not visible outside of file

singletons
