# Specio::Constraint::AnyDoes(3pm)

A class for constraints which require a class name or an object that does a specific role

## NAME

Specio::Constraint::AnyDoes - A class for constraints which require a class name or an object that does a specific role

## VERSION

version 0.53

## SYNOPSIS

```
    my $type = Specio::Constraint::AnyDoes->new(...);
    print $type->role;
```

## DESCRIPTION

This is a specialized type constraint class for types which require a class name or an object that does a specific role.

## API

This class provides all of the same methods as Specio::Constraint::Simple, with a few differences:

### Specio::Constraint::AnyDoes-\>new( ... )

The `"parent"` parameter is ignored if it passed, as it is always set to the `"Defined"` type.

The `"inline_generator"` and `"constraint"` parameters are also ignored. This class provides its own default inline generator subroutine reference.

This class overrides the `"message_generator"` default if none is provided.

Finally, this class requires an additional parameter, `"role"`. This must be a single role name.

### $any\_isa-\>role

Returns the role name passed to the constructor.

## ROLES

This class does the Specio::Constraint::Role::DoesType, Specio::Constraint::Role::Interface, Specio::Role::Inlinable, and MooseX::Clone roles.
