Specio::Constraint::ObjectCan - A class for constraints which require an object with a set of methods

version 0.48

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

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

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

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.

Returns an array reference containing the methods this constraint requires.

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