Member Function Documentation

override void AddConnection ( GraphNode  node, uint  cost  )

virtual

Add a connection from this node to the specified node.

If the connection already exists, the cost will simply be updated and no extra connection added.

Note

Only adds a one-way connection. Consider calling the same function on the other node to get a two-way connection.

Implements GraphNode.

override void ClearConnections ( bool  alsoReverse )

virtual

Remove all connections from this node.

Parameters

alsoReverse

if true, neighbours will be requested to remove connections to this node.

Implements GraphNode.

override bool ContainsConnection ( GraphNode  node )

virtual

Checks if this node has a connection to the specified node.

Reimplemented from GraphNode.

override void DeserializeNode ( GraphSerializationContext  ctx )

virtual

Reimplemented from GraphNode.

override void DeserializeReferences ( GraphSerializationContext  ctx )

virtual

Used to deserialize references to other nodes e.g connections.

Use the GraphSerializationContext.GetNodeIdentifier and GraphSerializationContext.GetNodeFromIdentifier methods for serialization and deserialization respectively.

Nodes must override this method and serialize their connections. Graph generators do not need to call this method, it will be called automatically on all nodes at the correct time by the serializer.

Reimplemented from GraphNode.

override void GetConnections ( GraphNodeDelegate  del )

virtual

Calls the delegate with all connections from this node.

Implements GraphNode.

override void Open ( Path  path, PathNode  pathNode, PathHandler  handler  )

virtual

Open the node.

Implements GraphNode.

override void RemoveConnection ( GraphNode  node )

virtual

Removes any connection from this node to the specified node.

If no such connection exists, nothing will be done.

Note

This only removes the connection from this node to the other node. You may want to call the same function on the other node to remove its eventual connection to this node.

Implements GraphNode.

override void SerializeNode ( GraphSerializationContext  ctx )

virtual

Reimplemented from GraphNode.

override void SerializeReferences ( GraphSerializationContext  ctx )

virtual

Used to serialize references to other nodes e.g connections.

Use the GraphSerializationContext.GetNodeIdentifier and GraphSerializationContext.GetNodeFromIdentifier methods for serialization and deserialization respectively.

Nodes must override this method and serialize their connections. Graph generators do not need to call this method, it will be called automatically on all nodes at the correct time by the serializer.
