public class DirectlyWithin
extends Within

Handler for "directlywithin" condition pointcut. This pointcut is not supported in AspectJ source. The directlywithin(ClassPattern) pointcut matches any join point lexically contained within a class matching ClassPattern, that is not also contained within a nested class.

public boolean unify(Pointcut otherpc,

Description copied from class: Pointcut
Attempt to unify two pointcuts. pc.unify(pc', unification) should return true if the pointcuts can be unified, and set the renamings appropriately in unification. There are two cases for unification: if unification.unifyWithFirst() is true, then the unification should only succeed if this pc can be renamed to pc', with the unification pointcut equal to this. Otherwise, the unification pointcut can be anything, as long as it can be renamed both to this and pc'.

A default implementation is provided, but all subclasses should override this - otherwise cflow CSE will be disabled for cflow that use these pointcuts.

Typical implementations for pointcuts that introduce no free variables are straightforward (see the And pointcut, for example). For pointcuts that introduce free variables, the Var.unify method is used to actually update the renamings (see the Args pointcut).

unify in class Within
otherpc - the pointcut that should be unify with this
unification - the Unification that should be set.
true iff the unification is succesful. If true is returned, then Unification.setPointcut(the unified pointcut) must have been called in the body of unify().
