Iterator over mutable graphs.

Required methods

fn graph_mut(&mut self, id: Option<&T>) -> Option<&mut Self::Graph>

Get the given graph mutabily.

Use the input None to get the default graph.

Note to implementors: the default graph should always exists.

fn graphs_mut<'a>(&'a mut self) -> Self::GraphsMut

Returns an iterator over the (mutable) graphs of the dataset.

fn insert_graph(&mut self, id: T, graph: Self::Graph) -> Option<Self::Graph>

Insert a graph in the dataset with the given name.

If a graph with the given name already exists, it is replaced and the previous graph definition is returned.

fn insert(&mut self, quad: Quad<T>)

Insert a quad in the dataset.

fn absorb<D: SizedDataset<T>>(&mut self, other: D) where
    D::Graph: SizedGraph<T>, 

Absorb the given other dataset.

Adds all the quads of other in the dataset.

Provided methods

fn default_graph_mut(&mut self) -> &mut Self::Graph
