Need convenience methods in Interface API to flatten interface inheritence
--------------------------------------------------------------------------
Key: WODEN-87
URL: http://issues.apache.org/jira/browse/WODEN-87
Project: Woden
Issue Type: New Feature
Components: Parser
Reporter: John Kaputin
We have a use case (from Axis2) for convenience methods on the
org.apache.woden.wsdl20.Interface API for additional convenience methods that
provide a flattened view on all interface child components - both those
directly declared and any inherited ones. Existing methods like
Interface.getInterfaceOperations and getInterfaceFaults return only the
components declared directly within the Interface (this is correct per the
description of those properties in the WSDL 2.0 spec). Currently the
getExtendedInterfaces method must be used to 'drill down' to get inherited
components. Cases like diamond inheritance must also be handled by the user
to avoid duplicates. The proposed convenience methods make all this transparent
to the user.
The proposed new methods on Interface are:
getAllInterfaceOperations
getAllIntefaceFaults
Some further consideration may be required about whether the existing
behaviour of getInterfaceOperations and getInterfaceFaults if actually useful
(ie. getting the declared components only). An alternative approach would be to
add methods like getDeclaredInterfaceOperations and change the behaviou of
getInterfaceOperations to return all operations - direclty declared and
inherited.
