    • getObjectId

      public String getObjectId()
      Description copied from interface: TMObjectIF
      PUBLIC: Gets the id of this object. The object id is part of the topic map id space, and must be unique. The object id is not significant (or unique) outside the current topic map. The object id is immutable. The object id is thus stable through this object's lifetime.
      Specified by:
      getObjectId in interface TMObjectIF
      Specified by:
      getObjectId in class ReadOnlyTMObject
      Returns:
      string which is this object's id.

    • getRoleTypes

      public Collection<TopicIF> getRoleTypes()
      Description copied from interface: AssociationIF
      PUBLIC: Gets a Collection of association role types found in this association. The returned collection does not contain any duplicates. Even if some roles have no type, null will not be returned as one of the role types in the returned set.
      Specified by:
      getRoleTypes in interface AssociationIF
      Returns:
      A Collection of TopicIF objects.
