 * The interface for the user group remote service.

 * Never modify or reference this interface directly. Always use {@link UserGroupServiceUtil} to access the user group remote service. Add custom service methods to {@link com.liferay.portal.service.impl.UserGroupServiceImpl} and rerun ServiceBuilder to automatically copy the method declarations to this interface.

 * This is a remote service. Methods of this service are expected to have security checks based on the propagated JAAS credentials because this service can be accessed remotely.
