Method Detail

init

public void init()

Description copied from interface: uka.graph.GraphNode

This method is called before a coloring is computed. If the graph is re-colored incrementally after a structural modification, this method is called again before the coloring algorihtm is restarted.

Specified by:

init in interface uka.graph.GraphNode

getDegree

public int getDegree()

Description copied from interface: uka.graph.GraphNode

The degree of this graph node.

Specified by:

getDegree in interface uka.graph.GraphNode

getRank

public int getRank()

Description copied from interface: uka.graph.GraphNode

The rank of this graph node is unique among all nodes of the graph.

Specified by:

getRank in interface uka.graph.GraphNode

getNeighbors

public IntIterator getNeighbors()

Description copied from interface: uka.graph.GraphNode

Iterates over all ranks of which are connected to this node.

Specified by:

getNeighbors in interface uka.graph.GraphNode

getColor

public int getColor(int rank)

Description copied from interface: uka.graph.GraphNode

Gets the current color of the node with the given rank. A call to this method is only valid, if the given rank is the rank of this node or a rank of a neighbor node.

Specified by:

getColor in interface uka.graph.GraphNode

setColor

public void setColor(int rank,
                     int color)

Description copied from interface: uka.graph.GraphNode

Sets the color of the node with the given rank. The same restriction as in GraphNode.getColor(int) applies.

Specified by:

setColor in interface uka.graph.GraphNode

getColors

public IntIterator getColors()

Returns:

a sequence of colors with with this node and neighbor nodes are colored.

getRanks

public IntIterator getRanks(int color)

Returns:

a sequence of ranks of neighbor nodes that are colored with the given color.
