Re: [aspectj-users] issingleton() behavior
|
a singleton aspect will look like below, so it will be singleton as
relative to the aspect class visibility rule. If you have 2 unrelated
CL in which the aspect is (in fact are), you will have 2 aspect
classes, and thus 2 singletons instances (of 2 different aspect
classes), just as in OO.
aspect SingletonAspect {
private static SingletonAspect s_singleton;
// implicit method
public static SingletonAspect aspectOf() {
if (s_singleton == null) {
s_singleton = ... // instantiate the singleton instance of
SingletonAspect
}
return s_singleton;
}
....
}
