NAME

Class::Meta::Method - Class::Meta class method introspection

SYNOPSIS

  # Assuming MyApp::Thingy was generated by Class::Meta.
  my $class = MyApp::Thingy->my_class;
  my $thingy = MyApp::Thingy->new;

  print "\nMethods:\n";
  for my $meth ($class->methods) {
      print "  o ", $meth->name, $/;
      $meth->call($thingy);
  }

DESCRIPTION

This class provides an interface to the Class::Meta objects that describe methods. It supports a simple description of the method, a label, and its visibility (private, protected, or public).

Class::Meta::Method objects are created by Class::Meta; they are never instantiated directly in client code. To access the method objects for a Class::Meta-generated class, simply call its class method to retrieve its Class::Meta::Class object, and then call the methods() method on the Class::Meta::Class object.

INTERFACE

Instance Methods

name

  my $name = $meth->name;

Returns the method name.

package

  my $package = $meth->package;

Returns the method package.

desc

  my $desc = $meth->desc;

Returns the description of the method.

label

  my $desc = $meth->label;

Returns label for the method.

view

  my $view = $meth->view;

Returns the view of the method, reflecting its visibility. The possible values are defined by the following constants:

Class::Meta::PUBLIC
Class::Meta::PRIVATE
Class::Meta::PROTECTED

context

  my $context = $meth->context;

Returns the context of the method, essentially whether it is a class or object method. The possible values are defined by the following constants:

Class::Meta::CLASS
Class::Meta::OBJECT

class

  my $class = $attr->class;

Returns the Class::Meta::Class object that this method is associated with. Note that this object will always represent the class in which the method is defined, and not any of its subclasses.

call

  my $ret = $meth->call($obj, @args);

Calls the method on the $obj object, passing in any arguments. Note that it uses a goto to execute the method, so the call to call() itself will not appear in a call stack trace.
