NAME

Specio::Constraint::AnyCan - A class for constraints which require a class name or object with a set of methods

VERSION

version 0.40

SYNOPSIS

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

DESCRIPTION

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

API

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

Specio::Constraint::AnyCan->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, "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.

$any_can->methods

Returns an array reference containing the methods this constraint requires.

ROLES

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