Member Function Documentation

◆ Allocate()

template<typename Tspec , typename Tindex , Tindex Tmax>

Tindex NewGRFClass< Tspec, Tindex, Tmax >::Allocate ( uint32_t global_id )

static

Allocate a class with a given global class ID.

Parameters

global_id The global class id, such as 'DFLT'.

Returns: The (non global!) class ID for the class.

Note: Upon allocating the same global class ID for a second time, this first allocation will be given.

void NewGRFClass< Tspec, Tindex, Tmax >::Assign ( Tspec * spec )

static

Assign a spec to one of the classes.

Parameters

spec	The spec to assign.

Note: The spec must have a valid class index set.
