Class TransformingLeavesIterator<N extends AbstractDTNode<?,?,?,N>,D>

java.lang.Object

com.google.common.collect.UnmodifiableIterator<T>

com.google.common.collect.AbstractIterator<D>

de.learnlib.datastructure.discriminationtree.iterators.TransformingLeavesIterator<N,D>

Type Parameters:

N - node type

D - type of transformation result

All Implemented Interfaces:

Iterator<D>

public class TransformingLeavesIterator<N extends AbstractDTNode<?,?,?,N>,D>
extends AbstractIterator<D>

Iterator that traverses all leaves (no inner nodes) of a subtree of a given discrimination tree node. Additionally allows to specify a transformer that is applied to the leaf nodes. If the transformer yields null for an iterated leaf, the transformed value will be skipped.
