[platform-ui-dev] Activity and Role changes

[Kim Horne <Kim_Horne@xxxxxxxxxx>]

Chris McLaren and I have integrated
our separate roles/activities work this afternoon.  As a consequence,
the classes some of you are relying on may have been changed, moved or
deleted.

In particular, org.eclipse.ui.internal.roles.RoleManager
(and IDERoleManager) is gone.  This was used internally for various
role based work but it also exposed .isEnabledId(String) for determining
whether or not a given ID was active based on matching patterns with the
various activities.    Some of you were using this to filter
various contributions and I apologize for the breakage (but it was necessary,
I swear).  To accomplish this pattern matching, you used to do the
following:

        RoleManager.getInstance().isEnabledId(string);

Now you would do the this:

        IActivityManager
activityManager = ((Workbench)PlatformUI.getWorkbench()).getActivityManager();
        activityManager.match(string,
activityManager.getEnabledActivityIds());

.getActivityManager() may eventually
be moved into the IWorkbench API at some point or somewhere else that is
equally accessible.

There were of course other changes,
particularly in regards to how activities are activated and deactivated
(or enabled and disabled) and how you go about performing this state change
based on pattern matching (as above).  There will be updated proposals
and documents shortly but if you have any questions in the meantime please
feel free to ask.
