Interface PolygonExpression<T>

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.

Modifier and Type	Method	Description
GeometryExpression	getExteriorRing()	Returns the exterior ring of this Polygon.
GeometryExpression	getInteriorRingN(NumericExpression position)	Returns the nth interior ring in the Polygon.
NumericExpression	getNumInteriorRings()	Returns the number of interior rings in the Polygon.
