## Functions
template<typename E , typename T >
ArrayT< T >::item_t | ItemAtT (E idx, const T &t, typename ArrayT< T >::item_t t_unk)
| Helper template function that returns item of array at given index or t_unk when index is out of bounds.
template<typename E , typename T >
ArrayT< T >::item_t | ItemAtT (E idx, const T &t, typename ArrayT< T >::item_t t_unk, E idx_inv, typename ArrayT< T >::item_t t_inv)
| Helper template function that returns item of array at given index or t_inv when index == idx_inv or t_unk when index is out of bounds.
template<typename E , typename T >
CStrA | ComposeNameT (E value, T &t, const char *t_unk, E val_inv, const char *name_inv)
| Helper template function that returns compound bitfield name that is concatenation of names of each set bit in the given value or t_inv when index == idx_inv or t_unk when index is out of bounds.
CStrA | ValueStr (Trackdir td)
| Return name of given Trackdir.
CStrA | ValueStr (TrackdirBits td_bits)
| Return composed name of given TrackdirBits.
CStrA | ValueStr (DiagDirection dd)
| Return name of given DiagDirection.
CStrA | ValueStr (SignalType t)
| Return name of given SignalType.
