Constructor Details

ColoringImpl

public ColoringImpl(Map<V,Integer> colors,
 int numberColors)

Construct a new vertex coloring.

Parameters:

colors - the color map

numberColors - the total number of colors used

Method Details

getNumberColors

public int getNumberColors()

Get the number of colors.

Specified by:

getNumberColors in interface VertexColoringAlgorithm.Coloring<V>

Returns:

the number of colors

getColors

public Map<V,Integer> getColors()

Get the color map.

Specified by:

getColors in interface VertexColoringAlgorithm.Coloring<V>

Returns:

the color map

getColorClasses

public List<Set<V>> getColorClasses()

Get the color classes. A subset of vertices assigned to the same color is called a color class; every such class forms an independent set. This method returns a partitioning of the vertices in the graph in disjoint color classes.

Specified by:

getColorClasses in interface VertexColoringAlgorithm.Coloring<V>

Returns:

a list of color classes

toString

public String toString()

Overrides:

toString in class Object
