Struct fp_growth::tree::Tree [−][src]
pub struct Tree<T> { /* fields omitted */ }Tree<T> represents the main tree data struct will be used during the FP-Growth algorithm.
Implementations
impl<T: ItemType> Tree<T>[src]
pub fn new() -> Tree<T>[src]
Create a new FP-Growth tree with an empty root node.
pub fn generate_partial_tree(paths: &[Vec<Rc<Node<T>>>]) -> Tree<T>[src]
Generate a partial tree with the given paths. This function will be called during the algorithm.
pub fn add_transaction(&mut self, transaction: Vec<T>)[src]
Iterate the transaction and add every item to the FP-Growth tree.
pub fn update_route(&mut self, node: Rc<Node<T>>)[src]
Update the route table that records the item and its node list.
pub fn generate_prefix_path(&self, item: T) -> Vec<Vec<Rc<Node<T>>>>[src]
Generate the prefix paths that end with the given item.
pub fn get_all_nodes(&self, item: T) -> Vec<Rc<Node<T>>>[src]
Get all nodes that holds the given item.
pub fn get_all_items_nodes(&self) -> Vec<(T, Vec<Rc<Node<T>>>)>[src]
Get all nodes with the given item.
pub fn print(&self)[src]
Print out the tree.
