NAME ^

Aspect::Advice::After - Execute code after a function is called

SYNOPSIS ^

  use Aspect;
  
  after {
      # Trace all returning calls to your module
      print STDERR "Called my function " . $_->sub_name . "\n";
  
      # Suppress exceptions AND alter the results to foo()
      if ( $_->short_name eq 'foo' ) {
          if ( $_->exception ) {
              $_->return_value(1);
          } else {
              $_->return_value( $_->return_value + 1 );
          }
      }
  
  } call qr/^ MyModule::\w+ $/

DESCRIPTION ^

The after advice type is used to execute code after a function is called, regardless of whether or not the function returned normally or threw an exception.

The after advice type should be used when you need to potentially make multiple different changes to the returned value or the thrown exception.

If you only care about normally returned values you should use returning in the pointcut to exclude join points occuring due to exceptions.

If you only care about handling exceptions you should use throwing in the pointcut to exclude join points occuring due to normal return.
