All Implemented Interfaces:

DependencyPermutationFunction<T>, Serializable

public class RelationPermutationFunction<T extends Vector>
extends Object
implements DependencyPermutationFunction<T>, Serializable

An default DependencyPermutationFunction for permuting a Vector based on a dependecny path, represented as a list of DependencyRelations. A passed in PermutationFunction is used to permute the Vectors based on the path length.
