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

SYNOPSIS

Top

  use Aspect;

  # High-level creation
  my $pointcut1 = true { rand() > 0.5 };

  # Manual creation
  my $pointcut2 = Aspect::Pointcut::True->new(
    sub { rand() > 0.5 }
  );

DESCRIPTION

Top

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::True 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.
