NAME

Aspect::Pointcut::If - Pointcut that allows arbitrary Perl code

SYNOPSIS

   use Aspect;
   
   # High-level creation
   my $pointcut1 = if_true { rand() > 0.5 };
   
   # Manual creation
   my $pointcut2 = Aspect::Pointcut::If->new(
     sub { rand() > 0.5 }
   );
 
 

DESCRIPTION

Because Aspect's weaving phase technically occurs at run-time (relative to the overall process) it does not need to be limit itself only to conditions that are fully describable at compile-time.

Aspect::Pointcut::If allows you to take advantage of this to create your own custom run-time pointcut conditions, although for safety and purity reasons you are not permitted to create custom conditions that interact with the Aspect::Point object for the call.
