Detailed Description
template<typename K>
class csRedBlackTree< K >
A red-black-tree.
- Remarks:
- Does not allow duplicate keys.
Uses csComparator<> for key comparisons.
Only stores keys. If you need a key-value-map, look at csRedBlackTreeMap.
Definition at line 48 of file redblacktree.h.
Constructor & Destructor Documentation
| csRedBlackTree< K >::csRedBlackTree | ( | size_t | allocatorBlockSize = 4096 |
) | [inline] |
Construct a new tree.
- Parameters:
-
allocatorBlockSize Block size in bytes used by the internal block allocator for nodes.

Member Function Documentation
| bool csRedBlackTree< K >::Contains | ( | const K & | key | ) | const [inline] |

Definition at line 767 of file redblacktree.h.
| bool csRedBlackTree< K >::Delete | ( | const K & | key | ) | [inline] |
Delete a key.
