ExtractTimeFilterVisitor (GeoWave Spatial and Temporal Support 2.0.0 API)

java.lang.Object
- org.geotools.filter.visitor.NullFilterVisitor
- - org.locationtech.geowave.core.geotime.util.ExtractTimeFilterVisitor

All Implemented Interfaces:

org.opengis.filter.expression.ExpressionVisitor, org.opengis.filter.FilterVisitor
```
public class ExtractTimeFilterVisitor
extends org.geotools.filter.visitor.NullFilterVisitor
```
This class can be used to get Time range from an OpenGIS filter object. GeoWave then uses this time range to perform a spatial intersection query.
Only those time elements associated with an index are extracted. At the moment, the adapter only supports temporal indexing on a single attribute or a pair of attributes representing a time range.
