java.lang.Object javax.management.relation.RelationTypeSupport
A RelationTypeSupport object implements the RelationType interface.
It represents a relation type, providing role information for each role expected to be supported in every relation of that type.
A relation type includes a relation type name and a list of role infos (represented by RoleInfo objects).
A relation type has to be declared in the Relation Service:
- either using the createRelationType() method, where a RelationTypeSupport object will be created and kept in the Relation Service
- either using the addRelationType() method where the user has to create an object implementing the RelationType interface, and this object will be used as representing a relation type in the Relation Service.
