Constructor and Description
IndexedHierarchicalGraph(int levelCount) Creates an IndexedHierarchicalGraph with the given number of levels.

Method Summary

Modifier and Type	Method and Description
abstract N	convertNodeBetweenLevels(int inputLevel, N node, int outputLevel) Converts the node at the input level into a node at the output level.
int	getLevelCount() Returns the number of levels in this hierarchical graph.
void	setLevel(int level) Switches the graph into the given level so all future calls to the getConnections methods act as if the graph was just a simple, non-hierarchical graph at that level.

Creates an IndexedHierarchicalGraph with the given number of levels.

Method Detail

getLevelCount

public int getLevelCount()

Description copied from interface: HierarchicalGraph

Returns the number of levels in this hierarchical graph.

Specified by:

getLevelCount in interface HierarchicalGraph<N>

setLevel

public void setLevel(int level)

Description copied from interface: HierarchicalGraph

Switches the graph into the given level so all future calls to the getConnections methods act as if the graph was just a simple, non-hierarchical graph at that level.

Specified by:

setLevel in interface HierarchicalGraph<N>

Parameters:

level - the level to set

convertNodeBetweenLevels

public abstract N convertNodeBetweenLevels(int inputLevel,
                                           N node,
                                           int outputLevel)

Description copied from interface: HierarchicalGraph

Converts the node at the input level into a node at the output level.

Specified by:

convertNodeBetweenLevels in interface HierarchicalGraph<N>

Parameters:

inputLevel - the input level

node - the node at the input level

outputLevel - the output level

Returns:
