GeometryIndexed

Template container indexed by polytope geometry types.

Defined in Rodin/Geometry/GeometryIndexed.h

template <
  class T>
class GeometryIndexed;

Template parameters
T	Type of values to store

Container that maps polytope types to associated data.

This class provides an efficient mapping from polytope geometry types (Point, Segment, Triangle, etc.) to arbitrary data of type T. It uses compile-time knowledge of the number of polytope types to provide O(1) access with minimal memory overhead.

Usage Example

// Store quadrature orders for each polytope type
GeometryIndexed<int> quadratureOrders = {
  {Polytope::Type::Point, 1},
  {Polytope::Type::Segment, 2},
  {Polytope::Type::Triangle, 3},
  {Polytope::Type::Quadrilateral, 4},
  {Polytope::Type::Tetrahedron, 5},
  {Polytope::Type::Hexahedron, 6}
  {Polytope::Type::Wedge, 7}
};
int order = quadratureOrders[Polytope::Type::Triangle]; // Returns 3
