Badger::Data::Type - base class for data types

This module implements a base class for data types.

An optional name for the data type.

An optional namespace for the data type.

An optional base data type.

An optional list of validation facets.

The following methods are defined in addition to those inherited from the Badger::Base base class.

This is aliased to the init_type() method.

This is the initialisation method for a data type. It is called automatically when a data type object is created via the new() method inherited from the Badger::Base base class.

Returns the name of the data type as specified via the name configuration option. If no name was specified then an automatically generated name is returned based on the class name with the "Badger::Data::Type" prefix removed and all "::" sequences replaced with periods, e.g. a data type "Badger::Data::Type::Foo::Bar" would yield a name of "Foo.Bar".

Returns the namespace for the data type, or "undef" is none is defined.

Returns the base data type, or "undef" is none is defined.

Returns a reference to a list of validation facets defined for the data type.

This constant method always returns the value 0. Subclasses representing simple data types should re-define this to return the value 1.

This constant method always returns the value 0. Subclasses representing complex data types should re-define this to return the value 1.

Applies a new validation facet to the data type.

Validates the value passed by reference as the first argument. It calls the "validate()" method of each of the validation facets in turn.
