Method Details

getPrev

@NonNull V getPrev(@NonNull V vertex,
 int index)

Returns the previous vertex associated with the specified vertex and incoming arrow index.

Parameters:

vertex - a vertex

index - index of incoming arrow

Returns:

the previous vertex

See Also:

• getPrevCount(V)

getPrevArrow

@Nullable A getPrevArrow(@NonNull V vertex,
 int index)

Returns the arrow data associated with the specified vertex and the specified incoming arrow index.

Parameters:

vertex - a vertex

index - index of incoming arrow

Returns:

the arrow

See Also:

• getPrevCount(V)

getPrevCount

int getPrevCount(@NonNull V vertex)

Returns the number of previous vertices at the specified vertex.

This number is the same as the number of incoming arrows at the specified vertex.

Parameters:

vertex - a vertex

Returns:

the number of previous vertices
