assumeGroupLeadership

public void assumeGroupLeadership()

Description copied from interface: GMSContext

lets this instance become a group leader explicitly Typically this can be employed by an administrative member to become a group leader prior to shutting down a group of members simultaneously. For underlying Group Communication Providers who don't support the feature of a explicit leader role assumption, the implementation of this method would be a no-op.
