Detailed Description

template<typename T>
class Acts::AnyGridConstView< T >

Type-safe view into a grid with const access.

Template Parameters

T	Type of values stored in the grid

This class provides a type-safe interface to access grid objects through the type-erased IGrid interface with const access only. It ensures that the grid being viewed contains values of the expected type T.

Example usage:

const Grid<double, Axis> grid(...);
AnyGridConstView<double> view(grid);
double value = view.atLocalBins({1});  // Read-only access
