Method Summary

double	getArea() The operation "area" shall return the area of this GenericSurface.
Envelope	getEnvelope()
double	getPerimeter()

Method Detail

getPerimeter

double getPerimeter()

Returns:

the length of all boundaries of the surface in a reference system appropriate for measuring distances.

getArea

double getArea()

The operation "area" shall return the area of this GenericSurface. The area of a 2 dimensional geometric object shall be a numeric measure of its surface area Since area is an accumulation (integral) of the product of two distances, its return value shall be in a unit of measure appropriate for measuring distances squared.

Returns:

the area

getEnvelope

Envelope getEnvelope()

Returns:

the bounding box of the surface
