NAME

Language::MuldisD::Ext::Spatial - Muldis D extension for spatial data types and operators

VERSION

This document is Language::MuldisD::Ext::Spatial version 0.5.1.

PREFACE

This document is part of the Muldis D language specification, whose root document is Language::MuldisD; you should read that root document before you read this one, which provides subservient details.

DESCRIPTION

Muldis D has a mandatory core set of system-defined (eternally available) entities, which is referred to as the Muldis D core or the core; they are the minimal entities that all Muldis D implementations need to provide; they are mutually self-describing and are used to bootstrap the language; any entities outside the core, called Muldis D extensions, are non-mandatory and are defined in terms of the core or each other, but the reverse isn't true.

This current Spatial document describes the system-defined Muldis D Spatial Extension, which consists of spatial and/or geometric data types and operators.

This current document does not describe the polymorphic operators that all types, or some types including core types, have defined over them; said operators are defined once for all types in Language::MuldisD::Core.

This documentation is pending.

TYPE SUMMARY

Following are all the data types described in this document, arranged in a type graph according to their proper sub|supertype relationships (but that the first 3 just reappear from the core set to provide a similar context, and aren't re-described here):

sys.Core.Universal.Universal

    sys.Core.Universal.Empty

    sys.Core.Scalar.Scalar

        # The following are all regular non-ordered scalar types.

        sys.Spatial.Spatial.Geometry
            sys.Spatial.Spatial.Point
            sys.Spatial.Spatial.Curve
                sys.Spatial.Spatial.LineString
                sys.Spatial.Spatial.CircularString
                sys.Spatial.Spatial.CompoundCurve
            sys.Spatial.Spatial.Surface
                sys.Spatial.Spatial.CurvePolygon
                    sys.Spatial.Spatial.Polygon
            sys.Spatial.Spatial.GeometryCollection
                sys.Spatial.Spatial.MultiPoint
                sys.Spatial.Spatial.MultiCurve
                    sys.Spatial.Spatial.MultiLineString
                sys.Spatial.Spatial.MultiSurface
                    sys.Spatial.Spatial.MultiPolygon

This documentation is pending.

SYSTEM-DEFINED SPATIAL SCALAR DATA TYPES

These non-core scalar data types describe common kinds of spatial or geometric figures. Of course, dealing with these types in general isn't a perfect science; they stand to be revised or rewritten.
