Hash table based node list multi-container class. More...
#include <nodelist.hpp>
Public Types | |
| typedef Titem_ | Titem |
| Make #Titem_ visible from outside of class. | |
| typedef Titem_::Key | Key |
| Make Titem_::Key a property of #HashTable. | |
| typedef SmallArray< Titem_, 65536, 256 > | CItemArray |
| Type that we will use as item container. | |
|
typedef CHashTableT< Titem_, Thash_bits_open_ > | COpenList |
| How pointers to open nodes will be stored. | |
|
typedef CHashTableT< Titem_, Thash_bits_closed_ > | CClosedList |
| How pointers to closed nodes will be stored. | |
| typedef CBinaryHeapT< Titem_ > | CPriorityQueue |
| How the priority queue will be managed. | |
