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 47 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.
Definition at line 439 of file redblacktree.h.
Member Function Documentation
| bool csRedBlackTree< K >::Contains | ( | const K & | key | ) | const [inline] |
Check whether a key is in the tree.
- Remarks:
- This is rigidly equivalent to Contains(key), but may be considered more idiomatic by some.
Definition at line 481 of file redblacktree.h.
| bool csRedBlackTree< K >::Delete | ( | const K & | key | ) | [inline] |
Delete a key.
- Returns:
- Whether the deletion was successful. Fails if the key is not in the tree.
Definition at line 464 of file redblacktree.h.
| void csRedBlackTree< K >::DeleteAll | ( | ) | [inline] |
Delete all keys.
Reimplemented in csRedBlackTreeMap< K, T >.
