Package uk.ac.ebi.utils.collections

Class TupleIterator<T>

java.lang.Object

uk.ac.ebi.utils.collections.TupleIterator<T>

All Implemented Interfaces:

Iterator<T[]>

public class TupleIterator<T>
extends Object
implements Iterator<T[]>

Takes an array of iterators and returns an iterator of tuples. Each tuple is built by taking the next element of each iterator. The iteration stops as son as there is at least one iterator that hasn't any more elements to return. The result is read-only and Iterator.remove() throws an UnsupportedOperationException, since its default implementation is not touched.
