Dear Hans Schippers,
Just complementing what Eric Bolden said:
>> However, I suspect it will not match other methods named "myMethod",
defined
>>in super- or subclasses of myClass. Is this correct? If so, what's the
>>rationale behind this?
It will match calls in sublcasses because any instance of an object of
your subclass is also
an instance of the super class. (Eric Bolden). On the other hand, If I
remeber correctly, This behavior is the same to execution pointucts. (Check
this and If you can send the answer)
>>Also, what about a method with more/less specific parameter types?
Parameters are matched exact, unless you specify something like:
- call(String MyClass.myMethod(..)) --> intercepts all calls to
"String myMethod with any arguments" in MyClass or Subtypes (with or with no
method overriden) and (Assuming no use the "within" designator).
- call(* MyClass.myMethod(..)) --> intercepts all calls to "*
myMethod with any arguments and returning any type" in MyClass or Subtypes
(with or with no method overriden) and (Assuming no use the "within"
designator).
Henrique.
