Method Details

inverseOfDirectedGraph

public <V,
A> @NonNull MutableDirectedGraph<V,A> inverseOfDirectedGraph(@NonNull DirectedGraph<V,A> graph)

Creates a builder which contains a copy of the specified graph with all arrows inverted.

Type Parameters:

V - the vertex data type

A - the arrow data type

Parameters:

graph - a graph

Returns:

a new graph with inverted arrows

subsetOfDirectedGraph

public <V,
A> @NonNull MutableDirectedGraph<V,A> subsetOfDirectedGraph(@NonNull DirectedGraph<V,A> graph,
 @NonNull Predicate<V> vertexPredicate)

Creates a builder which contains the specified vertices, and only arrows from the directed graph, for the specified vertices.

Type Parameters:

V - the vertex data type

A - the arrow data type

Parameters:

graph - a graph

vertexPredicate - a predicate for the vertices

Returns:

a subset of the directed graph

addAll

public <V,
A> void addAll(@NonNull DirectedGraph<V,A> source,
 @NonNull MutableDirectedGraph<V,A> target)

Adds the source graph to the target graph.

Type Parameters:

V - the vertex type

A - the arrow type

Parameters:

source - the source graph

target - the target graph

addAll

public <V,
A,
VV,
AA> void addAll(@NonNull DirectedGraph<VV,AA> source,
 @NonNull MutableDirectedGraph<V,A> target,
 @NonNull Function<VV,V> vertexMapper,
 @NonNull Function<AA,A> arrowMapper)

Adds the source graph to the target graph.

Type Parameters:

V - the vertex type of the target graph
