# ABSTRACT: Method Meta Object for constructors
=pod
=head1 NAME
Class::MOP::Method::Constructor - Method Meta Object for constructors
=head1 VERSION
version 2.0401
=head1 SYNOPSIS
use Class::MOP::Method::Constructor;
my $constructor = Class::MOP::Method::Constructor->new(
metaclass => $metaclass,
options => {
debug => 1, # this is all for now
},
);
# calling the constructor ...
$constructor->body->execute($metaclass->name, %params);
=head1 DESCRIPTION
This is a subclass of C<Class::MOP::Method> which generates
constructor methods.
=head1 METHODS
=over 4
=item B<< Class::MOP::Method::Constructor->new(%options) >>
This creates a new constructor object. It accepts a hash reference of
options.
=over 8
=item * metaclass
This should be a L<Class::MOP::Class> object. It is required.
=item * name
The method name (without a package name). This is required.
=item * package_name
The package name for the method. This is required.
=item * is_inline
This indicates whether or not the constructor should be inlined. This
defaults to false.
=back
=item B<< $metamethod->is_inline >>
Returns a boolean indicating whether or not the constructor is
inlined.
=item B<< $metamethod->associated_metaclass >>
This returns the L<Class::MOP::Class> object for the method.
