NAME
Muldis::D::Ext::Spatial - Muldis D extension for spatial data types and operators
VERSION
This document is Muldis::D::Ext::Spatial version 0.120.0.
PREFACE
This document is part of the Muldis D language specification, whose root document is Muldis::D; 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 either used to bootstrap the language or they constitute a reasonable minimum level of functionality for a practically useable industrial-strength (and fully TTM-conforming) programming 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 Muldis::D::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:
sys.std.Core.Type.Universal
sys.std.Core.Type.Scalar
sys.std.Core.Type.DHScalar
# The following are all regular non-ordered scalar types.
sys.std.Spatial.Type.Geometry
sys.std.Spatial.Type.Point
sys.std.Spatial.Type.Curve
sys.std.Spatial.Type.LineString
sys.std.Spatial.Type.CircularString
sys.std.Spatial.Type.CompoundCurve
sys.std.Spatial.Type.Surface
sys.std.Spatial.Type.CurvePolygon
sys.std.Spatial.Type.Polygon
sys.std.Spatial.Type.GeometryCollection
sys.std.Spatial.Type.MultiPoint
sys.std.Spatial.Type.MultiCurve
sys.std.Spatial.Type.MultiLineString
sys.std.Spatial.Type.MultiSurface
sys.std.Spatial.Type.MultiPolygon
This documentation is pending.
DATA TYPES FOR SPATIAL ARTIFACTS
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.
