      getRoleTypes in interface AssociationIF
      Overrides:
      getRoleTypes in class Association
      Returns:
      A Collection of TopicIF objects.

    • addTheme

      public void addTheme(TopicIF theme)
      Description copied from interface: ScopedIF
      PUBLIC: Add a topic to this scope. (A topic used in a scope is also called a theme.) If the topic is already part of the scope the method call has no effect.
      Specified by:
      addTheme in interface ScopedIF
      Overrides:
      addTheme in class Association
      Parameters:
      theme - A topic to be added to this scope; an object implementing TopicIF.

    • removeTheme

      public void removeTheme(TopicIF theme)
      Description copied from interface: ScopedIF
      PUBLIC: Remove a topic from this scope. If the topic is not already in the scope this method has no effect. (A topic used in a scope is also called a theme.)
      Specified by:
      removeTheme in interface ScopedIF
      Overrides:
      removeTheme in class Association
      Parameters:
      theme - A topic to be removed from this scope; an object implementing TopicIF.

    • getType

      public TopicIF getType()
      Description copied from interface: TypedIF
      PUBLIC: Gets the type that this object is an instance of.
      Specified by:
      getType in interface TypedIF

      Returns:
      The type of this object; an object implementing TopicIF.

    • setType

      public void setType(TopicIF type)
      Description copied from interface: TypedIF

      Specified by:
      setType in interface TypedIF
      Overrides:
      setType in class Association
      Parameters:
      type - The type for this object; an object implementing TopicIF.

    • toString

      toString in class Association

    • 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
      Overrides:
      getObjectId in class TMObject
      Returns:

    • getTopicMap

      public TopicMapIF getTopicMap()
      Description copied from interface: TMObjectIF
      PUBLIC: Gets the topic map that this object belongs to. If the object has been removed from its topic map or not added to a topic map yet this will be null.

    • getItemIdentifiers

      The purpose is to enable the engine to detect when references to external objects refer to objects that are already present within the system, such as topic maps which are already loaded.

      Specified by:
      getItemIdentifiers in interface TMObjectIF
      Overrides:
      getItemIdentifiers in class TMObject
