# Moose::Meta::Role::Composite(3pm)

An object to represent the set of roles

## NAME

Moose::Meta::Role::Composite - An object to represent the set of roles

## VERSION

version 2.4001

## DESCRIPTION

A composite is a role that consists of a set of two or more roles.

The API of a composite role is almost identical to that of a regular role.

## INHERITANCE

`"Moose::Meta::Role::Composite"` is a subclass of Moose::Meta::Role.

## METHODS

### Moose::Meta::Role::Composite-\>new(%options)

This returns a new composite role object. It accepts the same options as its parent class, with a few changes:

- •

  roles

  This option is an array reference containing a list of Moose::Meta::Role object. This is a required option.

- •

  name

  If a name is not given, one is generated from the roles provided.

- •

  apply\_params(\\%role\_params)

  Creates a new RoleSummation role application with `%role_params` and applies the composite role to it. The RoleSummation role application class used is determined by the composite role's `"application_role_summation_class"` attribute.

- •

  reinitialize($metaclass)

  Like `"Class::MOP::Package->reinitialize"`, but doesn't allow passing a string with the package name, as there is no real package for composite roles.

## BUGS

See "BUGS" in Moose for details on reporting bugs.
