Class SortedSimpleFeatureCollection

Object

DecoratingSimpleFeatureCollection

SortedSimpleFeatureCollection

All Implemented Interfaces:

SimpleFeatureCollection, FeatureCollection<SimpleFeatureType,SimpleFeature>

public class SortedSimpleFeatureCollection
extends DecoratingSimpleFeatureCollection

A wrapper that will sort a feature collection using a size sensitive algorithm, in main memory for small collections, using secondary memory otherwise. The threshold is defined by the Hints.MAX_MEMORY_SORT feature count

Method Detail

features

public SimpleFeatureIterator features()

Description copied from interface: SimpleFeatureCollection

Obtain a SimpleFeatureIterator of the Features within this SimpleFeatureCollection.

The implementation of FeatureIterator must adhere to the rules of fail-fast concurrent modification. In addition (to allow for resource backed collections) the SimpleFeatureIterator.close() method must be called.

Example use:

 SimpleFeatureIterator iterator=collection.features();
 try {
     while( iterator.hasNext()  ){
          SimpleFeature feature = iterator.next();
          System.out.println( feature.getID() );
     }
 }
 finally {
     iterator.close();
 }
