NAME

Class::Meta::Constructor - Class::Meta class constructor introspection

SYNOPSIS

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

  print "\nConstructors:\n";
  for my $ctor ($class->constructors) {
      print "  o ", $ctor->name, $/;
      my $thingy = $ctor->call;
  }

DESCRIPTION

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

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

INTERFACE

Instance Methods

name

  my $name = $ctor->name;

Returns the constructor name.

package

  my $package = $ctor->package;

Returns the package name of the class that constructor is associated with.

desc

  my $desc = $ctor->desc;

Returns the description of the constructor.

label

  my $desc = $ctor->label;

Returns label for the constructor.

view

  my $view = $ctor->view;

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

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

call

  my $obj = $ctor->call(@params);

Executes the constructor for the class, passing the parameters to it. Note that it uses a goto to execute the constructor, so the call to call() itself will not appear in a call stack trace.
