Member Function Documentation

Add()

template<typename Tdir , uint items>

bool SmallSet< Tdir, items >::Add ( TileIndex  tile, Tdir  dir  )

inline

Adds tile & dir into the set, checks for full set Sets the 'overflowed' flag if the set was full.

Parameters

tile	tile
dir	and dir to add

Returns

true iff the item could be added (set wasn't full)

Definition at line 153 of file signal.cpp.

Get()

template<typename Tdir , uint items>

bool SmallSet< Tdir, items >::Get ( TileIndex *  tile, Tdir *  dir  )

inline

Reads the last added element into the set.

Parameters

tile	pointer where tile is written to
dir	pointer where dir is written to

Returns

false iff the set was empty

Definition at line 174 of file signal.cpp.

IsEmpty()

template<typename Tdir , uint items>

bool SmallSet< Tdir, items >::IsEmpty ( )

inline
