Hi all,
Apologies in advance if this question has been answered before
but so far my searching hasn't found much. I have a product based on the
Eclipse CDT (Helios) which is using the regular Eclipse Install New Software...
dialogs to connect to an internal repository. What I would like to do is filter
the list of available features shown to the user based on some custom criteria.
Using a simple example let's say that the repo has 2 features "FeatureA" and
"FeatureB" and I want to write a custom policy that only displays FeatureB to
the user. I've written a class that extends org.eclipse.equinox.p2.ui.Policy
and overrides getVisiableAvailableUIQuery() as follows:
public IQuery<IInstallableUnit> getVisibleAvailableIUQuery() {
IQuery<IInstallableUnit> query = QueryUtil.createQuery(
"select(x | x.id == $0)",
"FeatureB.feature.group" );
return query;
}
When I fire up Eclipse and open the Available Software dialog
pointed to my repo I only see FeatureB in the list. So far so good. If I then
enable "Group items by category" I then see both FeatureA and FeatureB.
Stepping through the code in QueryProvider.getQueryDescriptor() it looks as if
my IQuery is ignored and all features are displayed regardless. My assumption
was that grouping by category was purely a display option that wouldn't impact
the actual data retrieved but this doesn't seem to be the case.
Is there any way to accomplish what I'm trying to do here? Any
pointers would be much appreciated.
Thanks,
Glen
