Converting fromto our JSONYaml representation of the plane graph

Synopsis

Documentation

toAdjRep :: PlanarGraph s w v e f -> Gr (Vtx v e) (Face f) Source #

Transforms the planar graph into a format taht can be easily converted into JSON format. For every vertex, the adjacent vertices are given in counter clockwise order.

See toAdjacencyLists for notes on how we handle self-loops.

running time: \(O(n)\)

fromAdjRep :: proxy s -> Gr (Vtx v e) (Face f) -> PlanarGraph s Primal v e f Source #

Read a planar graph, given in JSON format into a planar graph. The adjacencylists should be in counter clockwise order.

running time: \(O(n)\)

buildGraph :: proxy s -> Gr (Vtx v e) (Face f) -> PlanarGraph s Primal () () () Source #

Builds the graph from the adjacency lists (but ignores all associated data)

reorder :: Vector (i :+ a) -> (i -> Int) -> Vector a Source #

fromAdjacencyLists :: forall s w h. (Foldable h, Functor h) => [(VertexId s w, h (VertexId s w))] -> PlanarGraph s w () () () Source #

Construct a planar graph from a adjacency matrix. For every vertex, all vertices should be given in counter clockwise order.

pre: No self-loops, and no multi-edges

running time: \(O(n)\).
