Manual Reference Pages - XML::PASTOR::BUILTIN::UNION (3)
XML::Pastor::Builtin::Union - Ancestor of all classes that correspond to whitespace separated union W3C simple types.
This module is used internally by XML::Pastor. You do not normally know much about this module to actually use XML::Pastor. It is
documented here for completeness and for XML::Pastor developers. Do not count on the interface of this module. It may change in
any of the subsequent releases. You have been warned.
This class descends from XML::Pastor::Builtin::SimpleType.
This class is used for grouping the <B>builtinB> classes that
have whitespace separated <B>unionB> content.
In W3C schemas it is possible to define a simple type to be a <B>unionB> of other simple types.
This class inherits many methods from its ancestors. Please see XML::Pastor::Builtin::SimpleType for
<B>OBJECT METHODB> overriden from XML::Pastor::SimpleType.
Normaly the <B>xml_validateB> method checks an atomic value. However, <B>unionB> types
are aggregate types whose values may correspond to a value from any of the
member types. The member types are known via the <B>memberTypesB> and
<B>memberClassesB> properties (see XML::Pastor::Schema::SimpleType).
For each <B>memberClassB>, this method will instatiate an object and run <B>xml_validateB> on it.
If any of these invocations return TRUE, this method will also return TRUE. If all die, this
method will then die with an error message.
BUGS & CAVEATS
There no known bugs at this time, but this doesnt mean there are arent any.
Note that, although some testing was done prior to releasing the module, this should still be considered alpha code.
So use it at your own risk.
Note that there may be other bugs or limitations that the author is not aware of.
