treap_algorithms provides basic algorithms to manipulate nodes forming a treap.
(1) the header node is maintained with links not only to the root but also to the leftmost node of the tree, to enable constant time begin(), and to the rightmost node of the tree, to enable linear time performance when used with the generic set algorithms (set_union, etc.);
(2) when a node being deleted has two children its successor node is relinked into its place, rather than copied, so that the only pointers invalidated are those referring to the deleted node.
treap_algorithms is configured with a NodeTraits class, which encapsulates the information about the node to be manipulated. NodeTraits must support the following interface:
Typedefs:
node
: The type of the node that forms the treap
node_ptr
: A pointer to a node
const_node_ptr
: A pointer to a const node
Static functions:
static node_ptr get_parent(const_node_ptr n);
static void set_parent(node_ptr n, node_ptr parent);
static node_ptr get_left(const_node_ptr n);
static void set_left(node_ptr n, node_ptr left);
static node_ptr get_right(const_node_ptr n);
static void set_right(node_ptr n, node_ptr right);

Requires: "header" must be the header node of a tree.
KeyNodePtrCompare is a function object that induces a strict weak ordering compatible with the strict weak ordering used to create the the tree. KeyNodePtrCompare can compare KeyType with tree's node_ptrs. 'lower_key' must not be greater than 'upper_key' according to 'comp'. If 'lower_key' == 'upper_key', ('left_closed' || 'right_closed') must be false.
Effects: Returns an a pair with the following criteria:
first = lower_bound(lower_key) if left_closed, upper_bound(lower_key) otherwise
second = upper_bound(upper_key) if right_closed, lower_bound(upper_key) otherwise
Complexity: Logarithmic.
Throws: If "comp" throws.
Note: This function can be more efficient than calling upper_bound and lower_bound for lower_key and upper_key.
Note: Experimental function, the interface might change.

Requires: "cloner" must be a function object taking a node_ptr and returning a new cloned node of it.
"disposer" must take a node_ptr and shouldn't throw.
Effects: First empties target tree calling void disposer::operator()(const node_ptr &)
for every node of the tree except the header.
Then, duplicates the entire tree pointed by "source_header" cloning each source node with node_ptr Cloner::operator()(const node_ptr &)
to obtain the nodes of the target tree. If "cloner" throws, the cloned target nodes are disposed using void disposer(const node_ptr &)
.
Complexity: Linear to the number of element of the source tree plus the. number of elements of tree target tree when calling this function.
Throws: If cloner functor throws. If this happens target nodes are disposed.

Requires: "header" must be the header node of a tree.
NodePtrCompare is a function object that induces a strict weak ordering compatible with the strict weak ordering used to create the the tree. NodePtrCompare compares two node_ptrs. "hint" is node from the "header"'s tree. NodePtrPriorityCompare is a priority function object that induces a strict weak ordering compatible with the one used to create the the tree. NodePtrPriorityCompare compares two node_ptrs.
Effects: Inserts new_node into the tree, using "hint" as a hint to where it will be inserted. If "hint" is the upper_bound the insertion takes constant time (two comparisons in the worst case). Rotates the tree according to "pcomp".
Complexity: Logarithmic in general, but it is amortized constant time if new_node is inserted immediately before "hint".
Throws: If "comp" throw or "pcomp" throw.

Requires: "header" must be the header node of a tree.
NodePtrCompare is a function object that induces a strict weak ordering compatible with the strict weak ordering used to create the the tree. NodePtrCompare compares two node_ptrs. "hint" is node from the "header"'s tree.
Effects: Inserts new_node into the tree, using "hint" as a hint to where it will be inserted. If "hint" is the upper_bound the insertion takes constant time (two comparisons in the worst case).
Complexity: Logarithmic in general, but it is amortized constant time if new_node is inserted immediately before "hint".
Throws: If "comp" throws.

KeyNodePtrCompare is a function object that induces a strict weak ordering compatible with the strict weak ordering used to create the the tree. NodePtrCompare compares KeyType with a node_ptr.
Effects: Checks if there is an equivalent node to "key" in the tree according to "comp" and obtains the needed information to realize a constant-time node insertion if there is no equivalent node.
Returns: If there is an equivalent value returns a pair containing a node_ptr to the already present node and false. If there is not equivalent key can be inserted returns true in the returned pair's boolean and fills "commit_data" that is meant to be used with the "insert_commit" function to achieve a constant-time insertion function.
Complexity: Average complexity is at most logarithmic.
Throws: If "comp" throws.
Notes: This function is used to improve performance when constructing a node is expensive and the user does not want to have two equivalent nodes in the tree: if there is an equivalent value the constructed object must be discarded. Many times, the part of the node that is used to impose the order is much cheaper to construct than the node and this function offers the possibility to use that part to check if the insertion will be successful.
If the check is successful, the user can construct the node and use "insert_commit" to insert the node in constant-time. This gives a total logarithmic complexity to the insertion: check(O(log(N)) + commit(O(1)).
"commit_data" remains valid for a subsequent "insert_unique_commit" only if no more objects are inserted or erased from the set.
