Specio::Constraint::ObjectCan(3) User Contributed Perl Documentation Specio::Constraint::ObjectCan(3)

# [SYNOPSIS](#SYNOPSIS)

```
    my $type = Specio::Constraint::ObjectCan->new(...);
    print $_, "\n" for @{ $type->methods };
```

# [DESCRIPTION](#DESCRIPTION)

This is a specialized type constraint class for types which require an object with a defined set of methods.

# [API](#API)

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

## [Specio::Constraint::ObjectCan->new( ... )](#Specio::Constraint::ObjectCan)

The "parent" parameter is ignored if it passed, as it is always set to the "Object" 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, "methods". This must be an array reference of method names which the constraint requires. You can also pass a single string and it will be converted to an array reference internally.

## [$object\_can->methods](#$object_can)

Returns an array reference containing the methods this constraint requires.

# [ROLES](#ROLES)

This class does the Specio::Constraint::Role::CanType, Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
