Class FilteredIterator<F extends Feature>

  • All Implemented Interfaces:
    Closeable, AutoCloseable, Iterator<F>, FeatureIterator<F>

    public class FilteredIterator<F extends Feature>
    extends Object
    implements Iterator<F>, FeatureIterator<F>
    Provides an implementation of Iterator that will filter contents using the provided filter.

    This is a *Generic* iterator not limited to Feature, this will become more interesting as Filter is able to evaulate itself with more things then just Features.

    This also explains the use of Collection (where you may have expected a FeatureCollection). However FeatureCollectoin.close( iterator ) will be called on the internal delgate.

        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.)
