    • insertEdge

      public void insertEdge(V source, V target)

    • deleteEdgeIfExists

      public void deleteEdgeIfExists(V source, V target)
      No-op if trying to delete edge that does not exist
      Since:
      2.0
      See Also:

    • deleteEdgeThatExists

      public void deleteEdgeThatExists(V source, V target)
      Throws:
      IllegalStateException - if trying to delete edge that does not exist
      Since:
      2.0
      See Also:

    • deleteEdge

      @Deprecated public void deleteEdge(V source, V target)
      Deprecated.
      use explicitly deleteEdgeThatExists(Object, Object) or deleteEdgeIfExists(Object, Object) instead. To preserve backwards compatibility, this method delegates to the latter.

    • insertNode

      public void insertNode(V node)
      Insert the given node into the graph.

    • deleteNode

      public void deleteNode(V node)
      Deletes the given node AND all of the edges going in and out from the node.

    • attachObserver

      public void attachObserver(IGraphObserver<V> go)
      Description copied from interface: IGraphDataSource
      Attaches a new graph observer to this graph data source. Observers will be notified in the order they have been registered.
      Specified by:
      attachObserver in interface IGraphDataSource<V>
      Parameters:
      go - the graph observer

    • attachAsFirstObserver

      public void attachAsFirstObserver(IGraphObserver<V> observer)
      Description copied from interface: IGraphDataSource
      Attaches a new graph observer to this graph data source as the first one. In the notification order this observer will be the first one as long as another call to this method happens.
      Specified by:
      attachAsFirstObserver in interface IGraphDataSource<V>
      Parameters:
      observer - the graph observer

    • detachObserver

      public void detachObserver(IGraphObserver<V> go)
      Description copied from interface: IGraphDataSource
      Detaches an already registered graph observer from this graph data source.
      Specified by:
      detachObserver in interface IGraphDataSource<V>
      Parameters:
      go - the graph observer

    • getAllNodes

      public Set<V> getAllNodes()
      Description copied from interface: IGraphDataSource
      Returns the complete set of nodes in the graph data source.
      Specified by:
      getAllNodes in interface IGraphDataSource<V>
      Returns:
      the set of all nodes

    • getTargetNodes

      public IMemoryView<V> getTargetNodes(V source)
      Description copied from interface: IGraphDataSource
      Returns the target nodes for the given source node. The returned data structure is an IMultiset because of potential parallel edges in the graph data source. The method must not return null.
      Specified by:
      getTargetNodes in interface IGraphDataSource<V>
      Parameters:
      source - the source node
      Returns:
      the multiset of target nodes

    • getSourceNodes

      public IMemoryView<V> getSourceNodes(V target)
      Description copied from interface: IBiDirectionalGraphDataSource
      Returns the source nodes for the given target node. The returned data structure is an IMultiset because of potential parallel edges in the graph data source. The method must not return null.
      Specified by:
      getSourceNodes in interface IBiDirectionalGraphDataSource<V>
      Parameters:
      target - the target node
      Returns:
      the multiset of source nodes

    • toString

      public String toString()
      Overrides:
      toString in class Object
