Constructor Detail

FeatureIteratorImpl

public FeatureIteratorImpl(FeatureCollection<? extends FeatureType,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 FeatureIterator<F extends Feature>
