IEnumStrategy

IEnumStrategy is used to enumirate all nodes/edges in graph. You don't need create own Depth-first search algorithm. You can call IGraph method ProcessDFS(IEnumStrategy* pEnumStrategy, ObjectId startedNode). You should pass your implementation of IEnumStrategy and first node.

• DefaultEnumStrategy - ProcessDFS supports default enumeration types.
  DES_NONE - don't use any default enumeration.
  DES_NODE - use enumeration, when each node will process one time. You don't need control enumeration in your IEnumStrategy.
  DES_EDGE - use enumeration, when each edge will process one time. You don't need control enumeration in your IEnumStrategy.

• StartProcessNode(ObjectId nodeId) - graph calls this method when start new node.

• NeedProcessChild(ObjectId nodeId, ObjectId childId, ObjectId edgeId) - return true if graph needs to process childId node from childId using edgeId.

• FinishProcessNode(ObjectId nodeId) - calls when we finish process current node and all them children.

• GetDefaultStrategy() - return default enumeraion type DefaultEnumStrategy.

• StartProcessEdge(ObjectId edgeId) - start process new edge.

• FinishProcessEdge(ObjectId edgeId) - finish process edge and all nodes which were connected with parent node using edgeId.
