pub struct TripleStore { /* fields omitted */ }

Storage for triples.

Methods

impl TripleStore

pub fn new() -> TripleStore

Constructs a new triple store.

pub fn count(&self) -> usize

Returns the number of triples that are stored.

pub fn is_empty(&self) -> bool

Checks if the triple store is empty.

pub fn add_triple(&mut self, triple: &Triple)

Adds a new triple to the store.

pub fn remove_triple(&mut self, triple: &Triple)

Deletes the triple from the store.

pub fn get_triples_with_subject(&self, node: &Node) -> Vec<&Triple>

Returns all triples where the subject node matches the provided node.

pub fn get_triples_with_predicate(&self, node: &Node) -> Vec<&Triple>

Returns all triples where the predicate node matches the provided node.

pub fn get_triples_with_object(&self, node: &Node) -> Vec<&Triple>

Returns all triples where the object node matches the provided node.

pub fn get_triples_with_subject_and_object(
    &self,
    subject_node: &Node,
    object_node: &Node
) -> Vec<&Triple>

Returns all triples where the subject and object nodes match the provided nodes.

impl Default for TripleStore

fn default() -> TripleStore

Returns the "default value" for a type.

impl IntoIterator for TripleStore

type Item = Triple
