NAME

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


VERSION

       version 0.42


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.
