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 = $ctor->call($class->package);
         }

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

INTERFACE

   Constructors
       new

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

   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::TRUSTED
       Class::Meta::PROTECTED

       class

         my $class = $ctor->class;

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

       call

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

       Executes the constructor. Pass in the name of the class for which it is being executed
       (since, thanks to subclassing, it may be different than the class with which the
       constructor is associated). All other parameters will be passed to the constructor. Note
       that it uses a "goto" to execute the constructor, so the call to "call()" itself will not
       appear in a call stack trace.

       build

         $ctor->build($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 constructor was defined, and generates constructor method for the
       Class::Meta::Constructor, either by installing the code reference passed in the "code"
       parameter or by creating the constructor from scratch.

       Although you should never call this method directly, subclasses of
       Class::Meta::Constructor may need to override its behavior.
