hasNext
public boolean hasNext()
Description copied from interface:FeatureIterator
Does another Feature exist in this Iteration.Iterator defin: Returns true if the iteration has more elements. (In other words, returns true if next would return an element rather than throwing an exception.)

- Returns:
- true if more Features exist, false otherwise.
