>                 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}
