[Uddi4j-developers] RE: Collection class enhancement

[Stefan B. <ste...@ca...>]

I support David's proposal regarding adding methods for working with
collection classes.

I have a suggestion to at some point change the APIs to use a Java 2
collection interface such as List instead of using Vector which is an
implementation of List. The motivation for this is to allow users to use
a more efficient Java 2 collection class should they want to. Perhaps
this change could be introduced when the new collection methods are
added. The methods that use Vector could be deprecated but remain for
backwards compatibility. Comments ?

Subject: [Uddi4j-developers] Collection class enhancement

There are a number of areas where it would be nice to enhance the
usability of UDDI4J. The one that seems most urgent regards collection
classes.

The UDDI schema contains elements which represent nothing but
collections of other specific elements. In UDDI4J, these elements are
represented as objects, their contents are accessed by a get/set Vector
method. There is no direct mechanism to add/remove objects to the
collection. This is very awkward since the object sounds like it should
be a collection, but does not include any collection class methods. The
only thing you can do is get/set a Vector which is essentially the real
collection.

I propose adding a minimal set of collection class methods patterned
after some Vector methods. The following signatures would be appropriate
for IdentifierBag and CategoryBag since they both are collections of
KeyedReference objects.

Methods added are:
public void add(KeyedReference)
public boolean remove(KeyedReference)
public KeyedReference get(int index)
public int size()

Classes with this paradigm include:
   util.IdentifierBag collection of KeyedReferences
   util.CategoryBag collection of KeyedReferences
   util.DiscoveryURLs collection of  DiscoveryURL objects
   util.FindQualifiers collection of FindQualifier objects
   util.TmodelBag collection of Tmodel objects
   response.BusinessInfos collection of BusinessInfo objects
   response.PublisherAssertions collection of PublisherAssertion objects
   response.RelatedBusinessInfos collection of RelatedBusinessInfo
objects
   response.ServiceInfos collection of ServiceInfo objects
   response.TmodelInfos collection of TmodelInfo objects
   datatype.binding.BindingTemplates collection of BindingTemplate
objects
   datatype.binding.TModelInstanceDetails collection of
TmodelInstanceInfo
   objects
   datatype.business.Contacts collection of Contact objects
   datatype.service.BusinessServices collection of BusinessService
objects
