XML::Pastor::Schema::Type - Ancestor of XML::Pastor::Schema::SimpleType and XML::Pastor::Schema::ComplexType.


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::Schema::Object.


  my $type = XML::Pastor::Schema::Type->new();
  $type->setFields(name => 'Country', scope=> 'global', nameIsAutoGenerated=>0);
  print $type->name();  # prints 'Country'.
  print $type->scope(); # prints 'global'.
  print $type->base();  # prints 'Location'.
  print $type->derivedBy();     # prints 'extension'.


XML::Pastor::Schema::Type is an abstract ancestor of XML::Pastor schema type classes. That is, it is the ancestor of XML::Pastor::Schema::SimpleType and XML::Pastor::Schema::ComplexType.

It descends from XML::Pastor::Schema::Object. It adds a few more accessors to those that are already defined in this ancestor.





CONSTRUCTOR, inherited from XML::Pastor::Schema::Object.

The new() constructor method instantiates a new object. It is inheritable. Normally, one does not call the new method on XML::Pastor::Schema::Object. One rather calls it on the descendant subclasses.

Any -named- fields that are passed as parameters are initialized to those values within the newly created object.

See "new()" in XML::Pastor::Schema::Object.



Inherited accessors

Several accessors are inherited by this class from its ancestor XML::Pastor::Schema::Object. Please see XML::Pastor::Schema::Object for a documentation of those.

Accessors defined here


  my $base = $object->base();   # GET
  $object->base($base);             # SET

This is a W3C property.

The base of the type, that is, its ancestor within the W3C schema. This value comes directly from the W3C schema and written by the schema parser.


  my $bases = $object->baseClasses();   # GET
  $object->baseClasses($bases);             # SET

The base classes of this type, when it is generated by XML::Pastor. This value is computed at schema model resolution time by "resolve()" in XML::Pastor::Schema::Model.


  my $ct = $object->contentType();      # GET
  $object->contentType($ct);        # SET

The contentType of a type is either 'simple' or 'complex'. This is filled in by the new() methods of the descendant classes.


  my $derivedBy = $object->derivedBy(); # GET
  $object->derivedBy($derivedBy);           # SET

A type is derived either by 'restriction' or 'extension'. This value is deduced at parse time by the schema parser.


  my $final = $object->final(); # GET
  $object->final($final);           # SET

This is a W3C property.

A type can be final for 'restriction' or 'extension'. This field specifies that. Currently, XML::Pastor does NOT use the value of this field.


There no known bugs at this time, but this doesn't mean there are aren't 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.
