boolean hasNextX()
throws GridException
Iterator.hasNext(), but allows for failure
with exception. Often iterators are used to iterate through values
that have not or have partially been received from remote nodes,
and need to account for possible network failures, rather than
just returning false out of Iterator.hasNext() method.True if iterator contains more elements.GridException - If no more elements can be returned due
to some failure, like a network error for example.Iterator.hasNext()T nextX() throws GridException

that have not or have partially been received from remote nodes,
and need to account for possible network failures, rather than
throwing NoSuchElementException runtime exception.sTrue if iterator contains more elements.NoSuchElementException - If there are no more elements to
