Class NoContentIterator

  • All Implemented Interfaces:

    public class NoContentIterator
    extends Object
    implements Iterator<SimpleFeature>
    This iterator is used to indicate that contents could not be aquired.

    The normal Collection.iterator() method does not let us return an error (we always have to return an iterator). However can be used to return an NoSuchElementException.

    So we are basically going to lie, we are going to pretend their is content *once*, and when they ask for it we are going to hit them with a NoSuchElementExcetion. This is a mean trick, but it does convey the idea of asking for content that is supposed to be there and failing to aquire it.
