These are pointcuts, not methods, and can be considered to
exist only at compile/weave-time.  The documentation is in the
AspectJ programmers guide.

Matt's right about abstract aspects.  I suspect you want to say 
"public method execution in any type below package 
com.alloyinc.quiz.admin".  You could create a library aspect

  abstract aspect DoingThing {
     abstract pointcut withinTypes();
     pointcut publicMethodsWithinTypes() : withinTypes()
       && execution(public * *(..));
     before() : publicMethodsWithinTypes() { ... }
     // more advice
  }

then use it like this

  aspect DoingMyThing extends DoingThing {
     pointcut withinTypes() : within(com.alloyinc.quiz.admin..*);
  }

I believe Adrian, et al are working on a way to allow you to
configure a subaspect pointcut like this with config tools.
(Still more cool things coming out of those guys!)
