Class DelegateFeatureIterator<F extends Feature>

  • All Implemented Interfaces:
    Closeable, AutoCloseable, FeatureIterator<F>
    Direct Known Subclasses:
    DelegateSimpleFeatureIterator
    public class DelegateFeatureIterator<F extends Feature>
extends Object
implements FeatureIterator<F>
    A feature iterator that completely delegates to a normal Iterator, simply allowing Java 1.4 code to escape the caste (sic) system.

    This implementation checks the iterator to see if it implements Closeable in order to allow for collections that make use of system resources.

      • 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.)

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

      • next

        public F next()
       throws NoSuchElementException
        Description copied from interface: FeatureIterator
        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()
        Description copied from interface: FeatureIterator
        Closes this iterator and releases any system resources associated with it.
        Specified by:
        close in interface AutoCloseable
        Specified by:
        close in interface Closeable
        Specified by:
