Class BlockingAsyncIterator<T>

  • All Implemented Interfaces:
    java.util.Iterator<T>
    @ThreadSafe
public class BlockingAsyncIterator<T>
extends java.lang.Object
implements java.util.Iterator<T>
    This class is a wrapper over async iterator that implements java.util.Iterator interface. This is blocking wrapper on async iterator's getNext method which implements blocking hasNext and next methods of iterator interface. This class is threadsafe but that has the drawback of blocking on asyncIterator's getNext within a lock.
