Class ParallelIterator<Type1,​Type2>

  • All Implemented Interfaces:
    java.util.Iterator<Pair<Type1,​Type2>>
    public class ParallelIterator<Type1,​Type2>
extends java.lang.Object
implements java.util.Iterator<Pair<Type1,​Type2>>
    An iterator that iterates over two iterators simultaneously. Expects the ranges of both iterators to have the same length.

      ParallelIterator<Type1,​Type2>      		 create​(java.util.Iterator<Type1> iterator1, java.util.Iterator<Type2> iterator2)
      Convenience method that wraps the constructor call and lets the compiler determine the generic types.

      Pair<Type1,​Type2> next()
      The result will hold the result of the Iterator.next() call of the first iterator first, then the one of the second iterator.

      • ParallelIterator

        public ParallelIterator​(java.util.Iterator<Type1> iterator1,
                        java.util.Iterator<Type2> iterator2)
        Creates a ParallelIterator that iterates over the given iterators simultaneously.
        Parameters:
        iterator1 - the first iterator to iterate over. The return values of its Iterator.next() method will be first in the result pair of the next() method.
        iterator2 - the second iterator to iterate over. The return values of its Iterator.next() method will be second in the result pair of the next() method.
