Class GeoWaveFeatureReader

java.lang.Object

org.locationtech.geowave.adapter.vector.plugin.GeoWaveFeatureReader

All Implemented Interfaces:

Closeable, AutoCloseable, org.geotools.data.FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>

public class GeoWaveFeatureReader
extends Object
implements org.geotools.data.FeatureReader<org.opengis.feature.simple.SimpleFeatureType,org.opengis.feature.simple.SimpleFeature>

This class wraps a geotools data store as well as one for statistics (for example to display Heatmaps) into a GeoTools FeatureReader for simple feature data. It acts as a helper for GeoWave's GeoTools data store.
