Class FeatureIteratorImpl<F extends Feature>

  • All Implemented Interfaces:
    Closeable, AutoCloseable, FeatureIterator<F>
    Direct Known Subclasses:
    SimpleFeatureIteratorImpl

    public class FeatureIteratorImpl<F extends Feature>
    extends Object
    implements FeatureIterator<F>
    A convenience class for dealing with wrapping a Collection Iterator up as a FeatureIterator.

    Note this does not implement Iterator (FeatureIterator is a separate class).

    This class will check to see if the provided Iterator implements Closeable.

      • FeatureIteratorImpl

        public FeatureIteratorImpl​(Collection<F> collection)
        Create a new SimpleFeatureIterator using the Iterator from the given FeatureCollection.
        Parameters:
        collection - The SimpleFeatureCollection to perform the iteration on.
    • Method Detail

      • hasNext

        public boolean hasNext()
        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.)

        Specified by:
        hasNext in interface FeatureIterator<F extends Feature>
        Returns:
        true if more Features exist, false otherwise.
      • next

        public F next()
               throws NoSuchElementException
        Get the next Feature in this iteration.
        Specified by:
        next in interface FeatureIterator<F extends Feature>
        Returns:
        The next Feature
        Throws:
        NoSuchElementException - If no more Features exist.
      • close

        public void close()
        Required so SimpleFeatureCollection classes can implement close( SimpleFeatureIterator ).
        Specified by:
        close in interface AutoCloseable
        Specified by:
        close in interface Closeable
        Specified by:
        close in interface FeatureIterator<F extends Feature>
