Purpose

There are instances where you need to find if a particular user is assigned under a specific role.You don't have to iterate over a list of grants to achieve this.

QueryService qs = sf.getQueryService();
UserQuery userQuery = new UserQuery();
userQuery.getFilter().add(UserQuery.ACCOUNT.isEqual("Bang")); //User
ParticipantInfo pInfo = qs.getParticipant("Administrator"); //Role
userQuery.where(ParticipantAssociationFilter.forParticipant(pInfo));
User retUser = qs.findFirstUser(userQuery);
System.out.println("retUser:::::::::" + retUser);
