Detailed Description

template<typename grid_t>
struct Acts::InterpolatedBFieldMap< grid_t >::Cache

Cache for field cell to improve performance of field lookups.

This cache stores the current field cell which contains the interpolation data for a confined region of space. By caching the cell, subsequent lookups at nearby positions (e.g., during track propagation) can avoid expensive grid queries. The cache automatically updates when a position outside the current cell is queried.
