Trait Implementations

impl Flag for Digraph

fn induce(&self, p: &[usize]) -> Self

Returns the subflag induced by the vertices in the slice set.

fn name() -> String

A name for this type of flags. For instance "Graphe". This name is used for naming the associated data subdirectory.

fn all_flags(n: usize) -> Vec<Self>

Returns the set of all flags of size n.

fn superflags(&self) -> Vec<Self>

Return the list of flags of size self.size() + 1 that contain self as an induced subflag.

fn generate_next(previous: &[Self]) -> Vec<Self>

Return the list of flags of size self.size() + 1 that contain self as an induced subflag reduced modulo isomorphism.

fn generate(n: usize) -> Vec<Self>

Return the list of flags of size n reduced modulo isomorphism.

fn generate_typed_up(type_flag: &Self, g_vec: &[Self]) -> Vec<Self>

Return the list of flags of g_vec that can be rooted on the flag type_flag. Each different way to root this flag give a different flag in the result.

fn generate_typed(type_flag: &Self, size: usize) -> Vec<Self>

Return the list of flag of size size rooted on type_flag reduced modulo (typed) isomorphism.

fn select_type(&self, eta: &[usize]) -> Self

Reorder self so that the eta.len() first vertices are the values of eta in the corresonding order.
