NAME

Aspect::Pointcut::Highest - Pointcut for preventing recursive matching

SYNOPSIS

   use Aspect;
   
   # High-level creation
   my $pointcut1 = highest;
   
   # Manual creation
   my $pointcut2 = Aspect::Pointcut::Highest->new;

DESCRIPTION

For aspects including timers and other Aspect::Advice::Around-based advice, recursion can be significant problem.

The "highest" pointcut solves this problem by matching only on the highest invocation of a function. If the function is called again recursively within the first call, at any depth, the deeper calls will be not match and the advice will not be executed.
