Martin Desruisseaux reopened GEOT-1300:
---------------------------------------
> Isolate CanonicalSet as a subclass of WeakHashSet
> -------------------------------------------------
>
> Key: GEOT-1300
> URL: http://jira.codehaus.org/browse/GEOT-1300
> Project: GeoTools
> Issue Type: Sub-task
> Components: core referencing
> Affects Versions: 2.4-M3
> Reporter: Jody Garnett
> Assignee: Jody Garnett
> Fix For: 2.4-M4
>
>
> WeakHashSet is currently pulling double duty:
> - It functions as a normal set that happens to store its entries using
> WeakReferences
> - it has additional methods (ie canonicalize) in order to function in a
> manner similar to String.intern
> We should seperate these two concerns - primarily so what is going on can be
> understood.
> - WeakHashSet - remains as set of weak references, methods providing
> additional functionality will be deprecated
> - CanonicalSet cerated as an extension to WeakHashSet and proivdes a *unique*
> method
> This bug report is done when we have updated the code and provided user docs
> on the result.
> Sample use:
> {code}
> class FooFactory {
> public Foo create(String definition) {
> Foo created = new Foo(definition);
> return (Foo) canionicalSet.unique(created);
> }
> }
> {code}
