Description copied from interface: NodeNumbering

Has to be invoked before the data structure can be used. The data structure may only be used with nodes belonging to the given graph. After init() the content of the NodeNumbering is still undefined. Use fill if you want to define it.

Specified by:

init in interface NodeNumbering

Parameters:

g - the graph for which the NodeNumbering shall be defined.

fill

public void fill(int num)

Description copied from interface: NodeNumbering

Set the node number of all nodes to a given value.

Specified by:

fill in interface NodeNumbering

Parameters:

num - the value which shall be set.

                      int num)

Description copied from interface: NodeNumbering

Set the number of a single node.

Specified by:

setNumber in interface NodeNumbering

Parameters:

v - the node

num - the number to be set
