Method Details

commitChanges

void commitChanges(BitSet changed)

Called when all edge modifications are queued. After this method returns, BaseTopologicalOrderGraph.getTopologicalOrder(int) must be accurate for every node in the graph.

withNodeData

default <Solution_> void withNodeData(List<EntityVariablePair<Solution_>> nodes)

Called on graph creation to supply metadata about the graph nodes.

Parameters:

nodes - A list of entity/variable pairs, where the nth item in the list corresponds to the node with id n in the graph.

addEdge

void addEdge(int from,
 int to)

Called when a graph edge is added. The operation is added to a batch and only executed when commitChanges(BitSet) is called.

BaseTopologicalOrderGraph.getTopologicalOrder(int) is allowed to be invalid when this method returns.

removeEdge

void removeEdge(int from,
 int to)

Called when a graph edge is removed. The operation is added to a batch and only executed when commitChanges(BitSet) is called.

BaseTopologicalOrderGraph.getTopologicalOrder(int) is allowed to be invalid when this method returns.

forEachEdge

void forEachEdge(TopologicalOrderGraph.EdgeConsumer edgeConsumer)
