edu.rice.cs.plt.iter
Class BinaryMappedIterator<T1,T2,R>

java.lang.Object
  edu.rice.cs.plt.iter.BinaryMappedIterator<T1,T2,R>

All Implemented Interfaces:

Composite, java.util.Iterator<R>

public class BinaryMappedIterator<T1,T2,R>
extends java.lang.Object
implements java.util.Iterator<R>, Composite

An Iterator that applies a provided mapping lambda to each corresponding member of two source iterators. remove() delegates to each of the source iterators. Assumes the iterators have the same length.

Constructor Summary

BinaryMappedIterator(java.util.Iterator<? extends T1> source1, java.util.Iterator<? extends T2> source2, Lambda2<? super T1,? super T2,? extends R> map)

Method Summary

int	compositeHeight() Get the maximum path length from this node to a leaf.
int	compositeSize() Get the number of nodes in the tree rooted at this node.
boolean	hasNext()
