Re: [aspectj-users] super and extends in generic pointcuts

[Dénes Németh <mr.nemeth.denes@xxxxxxxxx>]

Hi

I manged to fix the matching for p11  public void func9(Collection<?
extends Simple1>s){ },
how is it possible to create a function to the second p12

pointcut p12() : execution (void Simple1.func10(Collection<? super>>
Interface1>));

Thanks,
Denes
