DirectedGraph class

An implementation of a graph with directed edges.

Inheritance

• Object
• Graph
• DirectedGraph

Constructors

DirectedGraph(Map<Vertex, List<Edge>> graph)

Properties

graph → Map<Vertex, List<Edge>>

This map is the representation of your directed graph.

final

hashCode → int

The hash code for this object.

no setter, inherited

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

getAllEdges() → List<Edge>

Returns a list of all edges in graph.

override

getAllVertices() → List<Vertex>

Returns a list of all vertices in graph.

override

getEdge(Vertex a, Vertex b) → Edge

Returns an Edge in a graph with Vertex a and b

override

getEdgeByString(String a, String b) → Edge

Searches graph and finds and returns an edge with the same name as the specified a and b string.

override

getEdgeWeight(Vertex a, Vertex b) → double

A Method to get the weight of an edge. Because the graph has directional nodes you need to specify a starting node a and an ending node b. Because this is a directed graph a and b are NOT interchangeable.

override

getNeighboringEdgesOfEdge(Edge edge) → List<DirectedEdge>

Gets all neighboring edges of an edge

override

getNeighboringEdgesOfEdgeByString(String a, String b) → List<DirectedEdge>

Gets all neighboring edges of an edge searched for by a and b

override

getOutgoingEdges(Vertex vertex) → List<DirectedEdge>

Gets all neighboring edges of a vertex

override

getOutgoingEdgesByString(String source) → List<DirectedEdge>

Gets all neighboring edges of a source that gets searched by string in graph

override

getPathWeight(Path path) → double

Gets the weight of a specified path

override

getVertex(Vertex vertex) → Vertex

Searches graph and finds and returns a vertex.

override

getVertexByString(String source) → Vertex

Searches graph and finds and returns a vertex with the same name as the specified source string.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toJson() → Map<String, dynamic>

toString() → String

A string representation of this object.

override

Operators

operator ==(Object other) → bool

The equality operator.
