• the service "id" must be one of the provided "ids"

Parameters:

pid - PID of the calling component (use 'config.service_pid()' or '(String)prop.get(Constants.SERVICE_PID)'; if null, PID filter is not added to the resulting target filter

ids - Component IDs to be filtered for; for empty list, no ids are added to the target filter
