Enum for dimensionality or topological dimension #220
Description
The new enum specified as:
/// An enum for *dimensionality* or *topological dimension* in the context of
/// geospatial applications.
enum Dimensionality {
/// A dimensionality representing a *punctual* geometry (or position, point,
/// vertex, node, marker etc.) with the topological dimension of `0`.
punctual(0),
/// A dimensionality representing a *linear* geometry (or chain, line string,
/// polyline, path, curve etc.) with the topological dimension of `1`.
linear(1),
/// A dimensionality representing an *areal* geometry (or polygon, area,
/// surface, box etc.) with the topological dimension of `2`.
areal(2),
/// A dimensionality representing a *volymetric* geometry (or tetrahedron,
/// polyhedron, volyme, cube etc.) with the topological dimension of `3`.
volymetric(3);
const Dimensionality(this.topologicalDimension);
/// The topological dimension (`0`: punctual, `1`: linear, `2`: areal,
/// `3`: volymetric).
final int topologicalDimension;
