PolygonExpression (JDO API 3.2.1-SNAPSHOT API)

All Superinterfaces:

ComparableExpression<T>, Expression<T>, GeometryExpression<T>
```
public interface PolygonExpression<T>
extends GeometryExpression<T>
```
Representation of a Polygon expression. Note that this is not part of the JDO spec, but a vendor extension to allow JDOQLTyped handling for geometry types.
