# Class::Meta::Method(3pm)

Class::Meta class method introspection

## 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, trusted, 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 `"my_class()"` method to retrieve its Class::Meta::Class object, and then call the `"methods()"` method on the Class::Meta::Class object.

## INTERFACE

### Constructors

*new*

A protected method for constructing a Class::Meta::Method object. Do not call this method directly; Call the `"add_method()"` method on a Class::Meta object, instead.

### 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::TRUSTED

  - 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

  *args*

A description of the arguments to the method. This can be anything you like, but I recommend something like a string for a single argument, an array reference for a list of arguments, or a hash reference for parameter arguments.

*returns*

A description of the return value or values of the method.

*class*

```
  my $class = $meth->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.

*build*

```
  $meth->build($class);
```

This is a protected method, designed to be called only by the Class::Meta class or a subclass of Class::Meta. It takes a single argument, the Class::Meta::Class object for the class in which the method was defined. Once it checks to make sure that it is only called by Class::Meta or a subclass of Class::Meta or of Class::Meta::Method, `"build()"` installs the method if it was specified via the `"code"` parameter to `"new()"`.

Although you should never call this method directly, subclasses of Class::Meta::Method may need to override it in order to add behavior.
