NAME
Badger::Data::Type - base class for data typesDESCRIPTION
This module implements a base class for data types.CONFIGURATION OPTIONS
name
An optional name for the data type.namespace
An optional namespace for the data type.base
An optional base data type.facets
An optional list of validation facets.METHODS
The following methods are defined in addition to those inherited from the Badger::Base base class.init()
This is aliased to the init_type() method.init_type($config)
This is the initialisation method for a data type. It is called automatically when a data type object is created via the new() method inherited from the Badger::Base base class.name()
Returns the name of the data type as specified via the name configuration option. If no name was specified then an automatically generated name is returned based on the class name with the "Badger::Data::Type" prefix removed and all "::" sequences replaced with periods, e.g. a data type "Badger::Data::Type::Foo::Bar" would yield a name of "Foo.Bar".namespace()
Returns the namespace for the data type, or "undef" is none is defined.base()
Returns the base data type, or "undef" is none is defined.facets()
Returns a reference to a list of validation facets defined for the data type.simple()
This constant method always returns the value 0. Subclasses representing simple data types should re-define this to return the value 1.complex()
This constant method always returns the value 0. Subclasses representing complex data types should re-define this to return the value 1.constrain($facet, @args)
Applies a new validation facet to the data type.validate($value_ref)
Validates the value passed by reference as the first argument. It calls the "validate()" method of each of the validation facets in turn.AUTHOR
