Class FeatureIteratorImpl<F extends Feature>

Object
FeatureIteratorImpl<F>
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 Details

    • 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>
