.Modifier and Type  Method and Description 

Curve 
createCurve(List<CurveSegment> segments)
Takes a list of curve segments with the appropriate endtostart
relationships and creates a curve.

Point 
createPoint(double[] coordinates)
Creates a point at the specified location specified by coordinates.

Point 
createPoint(Position position)
Creates a point at the specified position.

Primitive 
createPrimitive(Envelope envelope)
Returns an envelope as a primitive.

Ring 
createRing(List<OrientableCurve> curves)
Constructs a ring out of its component curves.

Solid 
createSolid(SolidBoundary boundary)
Constructs a solid by indicating its boundary as a collection of
shells organized into a solid boundary.

Surface 
createSurface(List<SurfacePatch> surfaces)
Takes a list of surface patches with the appropriate sidetoside
relationships and creates a surface.

Surface 
createSurface(SurfaceBoundary boundary)
Constructs a surface by indicating its boundary as a collection of
curves organized into the specified surface
boundary.

SurfaceBoundary 
createSurfaceBoundary(Ring exterior,
List<Ring> interiors)
Constructs a new surface boundary object representing the
boundary of a twodimensional surface.

CoordinateReferenceSystem 
getCoordinateReferenceSystem()
Returns the coordinate reference system in use for all primitive
geometric objects to be created through this interface.

@UML(identifier="GM_Primitive(GM_Envelope)", obligation=MANDATORY, specification=ISO_19107) Primitive createPrimitive(Envelope envelope) throws MismatchedReferenceSystemException, MismatchedDimensionException
EXAMPLE: In the case where the envelope is totally contained in the domain of validity of its coordinate reference system object, its associated primitive is the convex hull of the various permutations of the coordinates in the corners. For example, suppose that a particular envelope in 2D is defined as:
(we ignore the CRS below, assuming that it is a global variable), then we can take the various permutations of the ordinate values to create a list of polygon corners:lowerCorner = (x1, y1) upperCorner = (x2, y2)
If we then apply the convex hull function to the multi point, we get a polygon as a surface. The extent of a polygon in 2D is totally defined by its boundary (internal surface patches are planar and do not need interior control points) which gives us a data type to represent surface in 2D:MultiPoint
= { (x1, y1), (x1, y2), (x2, y1), (x2, y2) }
So that the surface boundary record contains the abovecited exterior ring, and an empty set of interior rings (convex sets have no "interior" holes).Ring
= {LineString
= { (x1, y1), (x1, y2), (x2, y2), (x2, y1), (x1, y1)} }

of the surface. In cases where an exterior cannot be unambiguously chosen (a bounded
cylinder, for example), this parameter may be null.interiors
