public class SocialRelationLocalServiceImpl
extends SocialRelationLocalServiceBaseImpl

The social relation local service. This service provides methods to handle unidirectional or bidirectional relations between users.

Relations between users can be unidirectional or bidirectional. The type of relation is determined by an integer constant. Some example relations are co-worker, friend, romantic partner, sibling, spouse, child, enemy, follower, parent, subordinate, supervisor.

The two users participating in the relation are designated as User1 and User2. In case of unidirectional relations User1 should always be the subject of the relation. You can use the following English sentence to find out which user to use as User1 and which to use as User2:

User1 is <relation> of User2 (e.g. User1 is parent of User2; User1 is supervisor of User2)

For bidirectional relations, the service automatically generates the inverse relation.
