[p2-dev] AbstractArtifactRepository subclass implementation requires use

[Thomas M Houser <tmhouser@xxxxxxxxxx>]

I have implemented a subclass of AbstractArtifactRepository
that provides readonly access to a repository.  It appears that the
only way to implement the getArtifacts(IArtifactRequest[]) method is to
reference the non-API class ArtifactRequest.  That is, the ArtifactRequest
methods setSourceRepository(IArtifactRepository) and perform(IProgressMonitor)
must be called (see the default SimpleArtifactRepository subclass to see
what I mean).  Why aren't these methods available in the IArtifactRequest
interface?
