Method Details

addVertex

void addVertex(@NonNull V v)

Adds a vertex to the graph if it is not already in the graph.

Parameters:

v - vertex data

removeVertex

void removeVertex(@NonNull V v)

Removes a vertex from the graph if it is in the graph.

Parameters:

v - vertex data

addArrow

void addArrow(@NonNull V v,
 @NonNull V u,
 @Nullable A a)

Adds an arrow from vertex v to vertex u.

This method adds additional an arrow if the arrow is already in the graph.

Parameters:

v - vertex data v

u - vertex data u

a - arrow data

removeArrow

void removeArrow(@NonNull V v,
 @NonNull V u,
 @Nullable A a)

Removes the first arrow from vertex v to vertex u that has the same data value.

Parameters:

v - vertex data v

u - vertex data u

a - arrow data

removeArrow

void removeArrow(@NonNull V v,
 @NonNull V u)

Removes the first arrow from vertex v to vertex u.

Parameters:

v - vertex data v

u - vertex data u

removeNext

void removeNext(@NonNull V v,
 int k)

Removes the k-th next arrow from vertex v.

Parameters:

v - vertex data v

k - index of arrow to be removed
