SOAP::WSDL::XSD::Typelib::Builtin(3)

NAME
SOAP::WSDL::XSD::Typelib::Builtin - Built-in XML Schema datatypes

DESCRIPTION
The SOAP::WSDL::XSD::Typelib::Builtin hierarchy implements all builtin types from the XML schema specification.

All XML schema derived types inherit from SOAP::WSDL::XSD::Typelib::Builtin::anyType.

These basic type classes are most useful when used as element or simpleType base classes.

Using SOAP::WSDL::XSD::Typelib::Builtin uses all of the builtin datatype classes.

All builtin types feature common behaviour described below in "OVERLOADED OPERATORS"

EXAMPLES
 my $bool = SOAP::WSDL::XSD::Typelib::Builtin::bool->new({ value => 0} );
 print $bool;    # prints "true"

 # implements <simpleType name="MySimpleType">
 #               <list itemType="xsd:string" />
 #            </simpleType>
 package MySimpleType;
 use SOAP::WSDL::XSD::Typelib::Builtin;
 use SOAP::WSDL::XSD::Typelib::SimpleType;

 use base qw(SOAP::WSDL::XSD::Typelib::SimpleType
    SOAP::WSDL::XSD::Typelib::Builtin::list
    SOAP::WSDL::XSD::Typelib::Builtin::string
 );
 1;

 # somewhere else
 my $list = MySimpleType->new({ value => [ 'You', 'shall', 'overcome' ] });
 print $list;   # prints "You shall overcome"

CLASS HIERARCHY
This is the inheritance graph for builtin types.

Types with [] marker describe types derived via the item in [] in the XML Schema specs.

Derivation is implemented via multiple inheritance with the derivation method as first item in the base class list.

OVERLOADED OPERATORS
Overloading is implemented via Class::Std's trait mechanism.

The following behaviours apply:

•   string context

    All classes use the "serialize" method for stringification.

•   bool context

    All classes derived from anySimpleType return their value in bool context

•   numeric context

    The boolean class returns 0 or 1 in numeric context.

    decimal, float and double (and derived classes) return their value in numeric context.

•   arrayification (@{})

    When accessed as a list ref, objects of all classes return a list ref with the object itself as single element.

    This is most useful for writing loops without additional conversions, especially in mini-languages found in templating systems or the like, which may not natively support converting to list refs.

    Instead of writing something like

     my $value = $complexType->get_ELEMENT;
     $value = ref $value eq 'ARRAY' ? $value : [ $value ];
     for (@{ $value }) { ... }

    you can just write

     for (@{ $complexType->get_ELEMENT }) {...}

    Note that complexTypes with undef elements still return undef when accessing an undefined element, so when an element may be empty you still have to write something like:

     my $value = $complexType->get_ELEMENT();
     if (defined $value) {
         for (@{ $value }) {
             ...
         }
     }

Subclasses

  SOAP::WSDL::XSD::Typelib::Builtin::anyType
Base class for all types

  SOAP::WSDL::XSD::Typelib::Builtin::anySimpleType
Base class for all simple types

  SOAP::WSDL::XSD::Typelib::Builtin::anyURI
Type representing URIs

  SOAP::WSDL::XSD::Typelib::Builtin::boolean
Represents boolean data.

Serializes to "true" or "false".

Everything true in perl and not "false" is deserialized as true.

Returns true/false in boolean context.

Returns 1 / 0 in numeric context.

boolean objects have a special method for deleting their value, because calling "setl_value(undef)" results in the value being set to false.

 $obj->delete_value();

  SOAP::WSDL::XSD::Typelib::Builtin::byte
byte integer objects.

  SOAP::WSDL::XSD::Typelib::Builtin::date
date values are automatically converted into XML date strings during setting:

 YYYY-MM-DD+zz:zz

The time zone is set to the local time zone if not included.

All input variants supported by Date::Parse are supported. You may even pass in dateTime strings - the time part will be ignored. Note that set_value is around 100 times slower when setting non-XML-time strings

When setting dates before the beginning of the epoch (negative UNIX timestamp), you should use the XML date string format for setting dates. The behaviour of Date::Parse for dates before the epoch is system dependent.

  SOAP::WSDL::XSD::Typelib::Builtin::dateTime
dateTime values are automatically converted into XML dateTime strings during setting:

 YYYY-MM-DDThh:mm:ss.nnnnnnn+zz:zz

The fraction of seconds (nnnnnnn) part is optional. Fractions of seconds may be given with arbitrary precision

The fraction of seconds part is excluded in converted values, as it would always be 0.

All input variants supported by Date::Parse are supported. Note that set_value is around 100 times slower when setting non-XML-time strings

  SOAP::WSDL::XSD::Typelib::Builtin::decimal
decimal is the base of all non-float numbers

  SOAP::WSDL::XSD::Typelib::Builtin::double

  SOAP::WSDL::XSD::Typelib::Builtin::duration

  SOAP::WSDL::XSD::Typelib::Builtin::ENTITY

  SOAP::WSDL::XSD::Typelib::Builtin::float

  SOAP::WSDL::XSD::Typelib::Builtin::gDay

  SOAP::WSDL::XSD::Typelib::Builtin::gMonth

  SOAP::WSDL::XSD::Typelib::Builtin::gMonthDay

  SOAP::WSDL::XSD::Typelib::Builtin::gYear

  SOAP::WSDL::XSD::Typelib::Builtin::gYearMonth

  SOAP::WSDL::XSD::Typelib::Builtin::hexBinary

  SOAP::WSDL::XSD::Typelib::Builtin::ID

  SOAP::WSDL::XSD::Typelib::Builtin::IDREF

  SOAP::WSDL::XSD::Typelib::Builtin::IDREFS
List of SOAP::WSDL::XSD::Typelib::Builtin::IDREF objects.

Derived by SOAP::WSDL::XSD::Typelib::Builtin::list.

  SOAP::WSDL::XSD::Typelib::Builtin::int

  SOAP::WSDL::XSD::Typelib::Builtin::integer

  SOAP::WSDL::XSD::Typelib::Builtin::language

  SOAP::WSDL::XSD::Typelib::Builtin::negativeInteger

  SOAP::WSDL::XSD::Typelib::Builtin::nonNegativeInteger

  SOAP::WSDL::XSD::Typelib::Builtin::nonPositiveInteger

  SOAP::WSDL::XSD::Typelib::Builtin::normalizedString
Tab, newline and carriage return characters are replaced by whitespace in set_value.

  SOAP::WSDL::XSD::Typelib::Builtin::NOTATION

  SOAP::WSDL::XSD::Typelib::Builtin::positiveInteger

  SOAP::WSDL::XSD::Typelib::Builtin::QName

  SOAP::WSDL::XSD::Typelib::Builtin::short

  SOAP::WSDL::XSD::Typelib::Builtin::string
String values are XML-escaped on serialization.

The following characters are escaped: <, >, &

  SOAP::WSDL::XSD::Typelib::Builtin::time
time values are automatically converted into XML time strings during setting:

 hh:mm:ss.nnnnnnn+zz:zz
 hh:mm:ss+zz:zz

The time zone is set to the local time zone if not included. The optional nanoseconds part is not included in converted values, as it would always be 0.

All input variants supported by Date::Parse are supported. You may even pass in dateTime strings - the date part will be ignored. Note that set_value is around 100 times slower when setting non-XML-time strings.

  SOAP::WSDL::XSD::Typelib::Builtin::token

  SOAP::WSDL::XSD::Typelib::Builtin::unsignedByte

  SOAP::WSDL::XSD::Typelib::Builtin::unsignedInt

  SOAP::WSDL::XSD::Typelib::Builtin::unsignedLong

  SOAP::WSDL::XSD::Typelib::Builtin::unsignedShort

CAVEATS

•   set_value

    In contrast to Class::Std-generated mutators (setters), set_value does not return the last value.

    This is for speed reasons: SOAP::WSDL never needs to know the last value when calling set_calue, but calls it over and over again...

BUGS AND LIMITATIONS

•   Thread safety

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

•   XML Schema facets

    No facets are implemented yet.
