class
xsdata.codegen.handlers.class_extension.
ClassExtensionHandler
(container)[source]¶ Bases:
xsdata.codegen.mixins.HandlerInterface
Reduce class extensions by copying or creating new attributes.
- Parameters
container (
ContainerInterface
) –
-
INCLUDES_NONE
= 0¶
-
INCLUDES_SOME
= 1¶
-
INCLUDES_ALL
= 2¶
-
container
: ContainerInterface = None¶
-
classmethod
process_native_extension
(target, extension)[source]¶ Native type flatten extension handler, ignore enumerations.
-
classmethod
process_simple_extension
(source, target, ext)[source]¶ Simple flatten extension handler for common classes eg SimpleType, Restriction.
- Steps:
If target is source: drop the extension.
If source is enumeration and target isn’t create default value attribute.
If both source and target are enumerations copy all attributes.
If both source and target are not enumerations copy all attributes.
If target is enumeration: drop the extension.
-
classmethod
process_complex_extension
(source, target, ext)[source]¶ Complex flatten extension handler for primary classes eg ComplexType, Element.
- Drop extension when:
source includes all target attributes
- Copy all attributes when:
source includes some of the target attributes
source has suffix attribute and target has at least one attribute
target has at least one suffix attribute
source or target class is abstract
-
find_dependency
(target, attr_type)[source]¶ Find dependency for the given extension type with priority.
Search priority: xs:SimpleType > xs:ComplexType
-
classmethod
compare_attributes
(source, target)[source]¶ Compare the attributes of the two classes and return whether the source includes all, some or none of the target attributes.
