IndexedDirectedGraphDirectedGraphFacade

public IndexedDirectedGraphDirectedGraphFacade(@NonNull IndexedDirectedGraph graph)

Method Details

getArrowCount

public int getArrowCount()

Description copied from interface: DirectedGraph

Returns the number of arrows.

Specified by:

getArrowCount in interface DirectedGraph<Integer,Integer>

Returns:

arrow count

getVertex

public @NonNull Integer getVertex(int index)

Description copied from interface: DirectedGraph

Gets the vertex data at the specified index.

Specified by:

getVertex in interface DirectedGraph<Integer,Integer>

Parameters:

index - an index

Returns:

vertex data

getNext

public @NonNull Integer getNext(@NonNull Integer v,
 int index)

Description copied from interface: BareDirectedVertexGraph

Returns the next vertex associated with the specified vertex and outgoing arrow index.

Specified by:

getNext in interface BareDirectedVertexGraph<Integer>

Parameters:

getNextArrow

public @NonNull Integer getNextArrow(@NonNull Integer v,
 int index)

Description copied from interface: BareDirectedGraph

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

Specified by:

getNextArrow in interface BareDirectedGraph<Integer,Integer>

Parameters:

v - a vertex

index - index of outgoing arrow
