NAME

SOAP::WSDL::XSD::Typelib::SimpleType - simpleType base class

DESCRIPTION

This module implements a base class for designing simple type classes modelling XML Schema simpleType definitions.

SYNOPSIS

    # example simpleType derived by restriction
    # XSD would be:
    # <simpleType name="MySimpleType">
    #    <restriction base="xsd:string" />
    # </simpleType>
    package MySimpleType;
    use Class::Std::Fast::Storable constructor => 'none';
    # restriction base implemented via inheritance
    use SOAP::WSDL::XSD::Typelib::Builtin;
    use SOAP::WSDL::XSD::Typelib::SimpleType;
    use base qw(
        # derive by restriction
        'SOAP::WSDL::XSD::Typelib::SimpleType::restriction',
        # restriction base
        'SOAP::WSDL::XSD::Typelib::Builtin::string'
    );

    # example simpleType derived by list.
    # XSD would be:
    # <simpleType name="MySimpleListType">
    #    <list itemTipe="xsd:string" />
    # </simpleType>
    package MySimpleListType;
    use Class::Std::Fast::Storable constructor => 'none';
    # restriction base implemented via inheritance
    use SOAP::WSDL::XSD::Typelib::Builtin;
    use base ('SOAP::WSDL::XSD::Typelib::SimpleType',
        'SOAP::WSDL::XSD::Typelib::Builtin::list',        # derive by list
        'SOAP::WSDL::XSD::Typelib::Builtin::string'       # list itemType
    );

How to write your own simple type

Writing a simple type class is easy - all you have to do is setting up the base classes correctly.

The following rules apply:

  • simpleType derived via list

    simpleType classes derived via list must inherit from these classes in exactly this order:

     SOAP::WSDL::XSD::Typelib::SimpleType
     SOAP::WSDL::XSD::Typelib::Builtin::list         # derive by list
     The::List::ItemType::Class                      # list itemType

    The::List::ItemType::Class can either be a builtin class (see SOAP::WSDL::XSD::Builtin) or another simpleType class (any other class implementing the right methods is supported too, but not for the faint of heart).

  • simpleType derived via restriction

    simpleType classes derived via restriction must inherit from these classes in exactly this order:

     SOAP::WSDL::XSD::Typelib::SimpleType               # you may leave out this
     SOAP::WSDL::XSD::Typelib::SimpleType::restriction  # derive by retriction
     The::Restriction::Base::Class                      # resytriction base

    The::Restriction::Base::Class can either be a builtin class (see SOAP::WSDL::XSD::Builtin) or another simpleType class.

    The slight inconsistency between the these variants is caused by the restriction element, which has different meanings for simpleType and complexType definitions.

BUGS AND LIMITATIONS

  • Thread safety

    SOAP::WSDL::XSD::Typelib::SimpleType uses Class::Std::Fast::Storable which uses Class::Std. Class::Std is not thread safe, so SOAP::WSDL::XSD::Typelib::SimpleType is neither.

  • union

    union simple types are not supported yet.

  • XML Schema facets

    No facets are implemented yet.
