Class MergeSortedIterator<A,​E>

  • Type Parameters:
    A -
    E -
    All Implemented Interfaces:
    java.util.Iterator<E>
    public class MergeSortedIterator<A,​E>
extends java.lang.Object
implements java.util.Iterator<E>
    This Iterator take two sorted iterators and merge them. Loop over iterators and use comparator in order to take items that are equals. The merge is done using the function mergeFunction
