NAME
Specio::Constraint::ObjectDoes - A class for constraints which require
an object that does a specific role
VERSION
version 0.48
SYNOPSIS
my $type = Specio::Constraint::ObjectDoes->new(...);
print $type->role;
DESCRIPTION
This is a specialized type constraint class for types which require 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::ObjectDoes->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.
$object_isa->role
Returns the role name passed to the constructor.
ROLES
This class does the Specio::Constraint::Role::DoesType,
Specio::Constraint::Role::Interface, and Specio::Role::Inlinable roles.
