Bug 8913

Description Erich Gamma 2002-02-01 06:18:45 EST

There is a usability issue in that the team operations are not reachable in 
some Java views, since we only show types and not Compilation Units.

It is desirable to allow VCM operations on types so that users can version from 
the type hiearchy or the type list view. The idea is that a top-level type is 
considered the same as the Compilation unit. We have done the same trick in 
VAME and it worked fine.

To achieve this we can change the JavaContributorResourceAdapter to map top-
level types to their containing CU. This enables the Team actions on types.

This results in the following problems:
1) VCM actions appear but are still disabled. I haven't verified it, but I 
suspect that VCM operations don't use the JavaContributorResourceAdapter but 
the IResource adapter as a consequence they target the ITypes and not the 
compilation units. IType returns null when asked for the adapted IResource. As 
a consequence the action appears in the menu but it is disabled. One idea would 
be to introduce an ITeamResourceAdapter that we could implement for Java. It 
knows that top level types are mapped to compilation units.

2) You get duplicate menu entries for the local history action contributions. 
One corresponds to the Resource actions and the other to the Java aware 
(structure aware) local history actions.
This could be solved by setting "adaptable" to false for the resource compare 
actions (org.eclipse.compare/plugin.xml).
