Class GeoWaveFeatureCollection

java.lang.Object

org.geotools.data.store.DataFeatureCollection

org.locationtech.geowave.adapter.vector.plugin.GeoWaveFeatureCollection

All Implemented Interfaces:

org.geotools.data.simple.SimpleFeatureCollection, org.geotools.feature.FeatureCollection<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>

public class GeoWaveFeatureCollection
extends org.geotools.data.store.DataFeatureCollection

This class is a helper for the GeoWave GeoTools data store. It represents a collection of feature data by encapsulating a GeoWave reader and a query object in order to open the appropriate cursor to iterate over data. It uses Keys within the Query hints to determine whether to perform special purpose queries such as decimation or distributed rendering.
