CyberKeyGeometry.transient constructor

CyberKeyGeometry.transient(Size size, { required double chamfer, required double edgeWidth, required double plunge, })

The geometry of an in-between face of a theme transition (values already quantised by the caller), from a second LRU so a transition never evicts the steady-state entries of cached.

Implementation

factory CyberKeyGeometry.transient(
  Size size, {
  required double chamfer,
  required double edgeWidth,
  required double plunge,
}) {
  final key = (size, chamfer, edgeWidth, plunge);
  final hit = _transient.remove(key);
  if (hit != null) return _transient[key] = hit;
  transientBuilds++;
  final g = _transient[key] = CyberKeyGeometry.build(
    size,
    chamfer: chamfer,
    edgeWidth: edgeWidth,
    plunge: plunge,
  );
  while (_transient.length > transientCapacity) {
    _transient.remove(_transient.keys.first);
  }
  return g;
}
