Re: [aspectj-users] intercept Class but not SubClass

["Ron Bodkin" <rbodkin@xxxxxxxxxxxxxx>]

Charles,

Whenever a subclass gets constructed, the base class constructor will also execute. However, you can discriminate based on the type of the object at runtime. Try this:

public pointcut baseConstruction() : execution( MyClass.new() ) && !this(MySubClass);

If you wanted to exclude ALL subclasses you could use this code:

private interface SubclassOfMyClass {}

declare parents: MyClass+ && !MyClass: SubclassOfMyClass;

public pointcut baseConstruction() : execution( MyClass.new() ) && !this(SubclassOfMyClass);
