Method Detail

getPrimitiveType

GeometricPrimitive.PrimitiveType getPrimitiveType()

Must always return GeometricPrimitive.PrimitiveType.Surface.

Specified by:

getPrimitiveType in interface GeometricPrimitive

Returns:

GeometricPrimitive.PrimitiveType.Surface

getSurfaceType

Surface.SurfaceType getSurfaceType()

Returns the type of surface.

Returns:

the type of surface

getArea

Measure getArea(Unit requestedBaseUnit)

Parameters:

requestedBaseUnit -

Returns:

area of the surface

getPerimeter

Measure getPerimeter(Unit requestedUnit)

Parameters:

requestedUnit -

Returns:

perimeter of the surface

getPatches

List<? extends SurfacePatch> getPatches()

Returns the patches that constitute this surface.

Returns:

the patches that constitute this surface

getExteriorRingCoordinates

Points getExteriorRingCoordinates()

Convenience method for accessing the control points of the exterior ring of a simple polygon surface.

NOTE: This method is only safe to use when the surface consists of a single planar patch that has a linear interpolated exterior ring.

Returns:

the control points

Throws:

IllegalArgumentException - if the surface has more than one patch, the patch is not planar or the exterior boundary is not completely described by linear interpolated segments

getInteriorRingsCoordinates

List<Points> getInteriorRingsCoordinates()

Convenience method for accessing the control points of the interior rings of a simple polygon surface.

NOTE: This method is only safe to use when the surface consists of a single planar patch that has linear interpolated interior rings.

Returns:

the control points

Throws:

IllegalArgumentException - if the surface has more than one patch, the patch is not planar or the interior boundaries are not completely described by linear interpolated segments
