-
static void init(node_ptr this_node) ;
Effects: Constructs an non-used list element, putting the next pointer to null: NodeTraits::get_next(this_node) == 0
Complexity: Constant
Throws: Nothing.
-
static bool unique(const_node_ptr this_node) ;
Requires: this_node must be in a circular list or be an empty circular list.
Effects: Returns true is "this_node" is the only node of a circular list: or it's a not inserted node: return !NodeTraitsget_next(this_node) || NodeTraits::get_next(this_node) == this_node
Complexity: Constant
Throws: Nothing.
-
static bool inited(const_node_ptr this_node) ;
Effects: Returns true is "this_node" has the same state as if it was inited using "init(node_ptr)"
Complexity: Constant
Throws: Nothing.
-
static void unlink_after(node_ptr prev_node) ;
Requires: prev_node must be in a circular list or be an empty circular list.
Effects: Unlinks the next node of prev_node from the circular list.
Complexity: Constant
Throws: Nothing.
-
static void unlink_after(node_ptr prev_node, node_ptr last_node) ;
Requires: prev_node and last_node must be in a circular list or be an empty circular list.
Effects: Unlinks the range (prev_node, last_node) from the linear list.
Complexity: Constant
Throws: Nothing.
-
static void link_after(node_ptr prev_node, node_ptr this_node) ;
Requires: prev_node must be a node of a linear list.
Effects: Links this_node after prev_node in the linear list.
Complexity: Constant
Throws: Nothing.
-
static void transfer_after(node_ptr p, node_ptr b, node_ptr e) ;
Requires: b and e must be nodes of the same linear list or an empty range. and p must be a node of a different linear list.
Effects: Removes the nodes from (b, e] range from their linear list and inserts them after p in p's linear list.
Complexity: Constant
Throws: Nothing.
-
static void init_header(node_ptr this_node) ;
Effects: Constructs an empty list, making this_node the only node of the circular list: NodeTraits::get_next(this_node) == this_node
.
Complexity: Constant
Throws: Nothing.
-
static node_ptr
get_previous_node(node_ptr prev_init_node, node_ptr this_node) ;
Requires: this_node and prev_init_node must be in the same linear list.
Effects: Returns the previous node of this_node in the linear list starting. the search from prev_init_node. The first node checked for equality is NodeTraits::get_next(prev_init_node).
Complexity: Linear to the number of elements between prev_init_node and this_node.
Throws: Nothing.
-
static std::size_t count(const_node_ptr this_node) ;
Requires: this_node must be in a linear list or be an empty linear list.
Effects: Returns the number of nodes in a linear list. If the linear list is empty, returns 1.
Complexity: Constant
Throws: Nothing.
-
static void swap_trailing_nodes(node_ptr this_node, node_ptr other_node) ;
Requires: this_node and other_node must be nodes inserted in linear lists or be empty linear lists.
Effects: Moves all the nodes previously chained after this_node after other_node and vice-versa.
Complexity: Constant
Throws: Nothing.
-
static node_ptr reverse(node_ptr p) ;
Effects: Reverses the order of elements in the list.
Returns: The new first node of the list.
Throws: Nothing.
Complexity: This function is linear to the contained elements.
-
static std::pair< node_ptr, node_ptr >
move_first_n_backwards(node_ptr p, std::size_t n) ;
Effects: Moves the first n nodes starting at p to the end of the list.
Returns: A pair containing the new first and last node of the list or if there has been any movement, a null pair if n leads to no movement.
Throws: Nothing.
Complexity: Linear to the number of elements plus the number moved positions.
-
static std::pair< node_ptr, node_ptr >
move_first_n_forward(node_ptr p, std::size_t n) ;
Effects: Moves the first n nodes starting at p to the beginning of the list.
Returns: A pair containing the new first and last node of the list or if there has been any movement, a null pair if n leads to no movement.
Throws: Nothing.
Complexity: Linear to the number of elements plus the number moved positions.
