Interface Algorithm.GraphTraversalContextCalculator<A,B,C>

Enclosing interface:

Algorithm

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface Algorithm.GraphTraversalContextCalculator<A,B,C>

Functional interface for a function answering the question "What must be the context of the node being added considering we know the added arc, the added node itself, and the context of the already traversed node adjacent to this arc?"

Example of implementation for context of type Double:

(addedArc, addedNode, addedArcDirection, prevNodeContext) -> prevNodeContext + addedArc.getValue().getLength()

Method Details

calculateNextNodeContext

C calculateNextNodeContext(Graph<A,B>.Arc addedArc,
 Graph<A,B>.Node addedNode,
 Algorithm.ArcRelativeDirection addedArcDirection,
 C prevNodeContext)

Function answering the question "What must be the context of the node being added considering we know the added arc, the added node itself, and the context of the already traversed node adjacent to this arc?"

Parameters:

addedArc - added arc

addedNode - added node

addedArcDirection - direction of the added arc, Algorithm.ArcRelativeDirection.OUTGOING or Algorithm.ArcRelativeDirection.INCOMING

prevNodeContext - context of the previous node

Returns:

context of the added node
