public class SubgraphRelocationManager
extends GraphLayoutManager

A SubgraphRelocationManager is a GraphLayoutManager that uses other GraphLayoutManagers to calculate the layout for every connected subgraph of the total Graph, and combines the various parts of the Graph in a rectangular, square-like shape (if possible) so that the total amount of area needed by the Graph is close to minimal.

Field Summary

static int	DEFAULT_BASELINE_INTERVAL The default value of the baseline interval parameter.
static double	DEFAULT_SUBGRAPH_PADDING The default value of the subgraph padding parameter.

Constructor Summary

SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager)
Create a new SubgraphRelocationManager with the specified subgraph GraphLayoutManager, default subgraph padding and (perhaps initially) no GraphRenderer.

SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager, GraphRenderer renderer)
Create a new SubgraphRelocationManager with the specified subgraph GraphLayoutManager and GraphRenderer and with default subgraph padding.

SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager, GraphRenderer renderer, double subgraphPadding)
Create a new SubgraphRelocationManager calculating layouts using the specified subgraph GraphLayoutManager, GraphRenderer and subgraph padding.

Method Summary

void	addSubgraphRelocationListener(SubgraphRelocationListener listener) Add a SubgraphRelocationListener to this SubgraphRelocationManager.
LayoutConverter	createLayoutConverter() This method passes the invocation to the subgraph layout manager, and returns 'null' when there is none.
void	doLayout() Calculates a layout for the complete Graph registered in this SubgraphRelocationManager.
int	getBaselineInterval()
GraphRenderer	getGraphRenderer()
GraphLayoutManager	getSubgraphLayoutManager()
double	getSubgraphPadding()
void	initialize(Graph graph) Invokes the initialize method of the subgraph GraphLayoutManager.
void	removeSubgraphRelocationListener(SubgraphRelocationListener listener) Remove a SubgraphRelocationListener from this SubgraphRelocationManager.
void	setBaselineInterval(int baselineInterval)
void	setGraphRenderer(GraphRenderer renderer)
void	setSubgraphLayoutManager(GraphLayoutManager subgraphLayoutManager)
void	setSubgraphPadding(double subgraphPadding)
void	stop() Sets a flag that will cause the SubgraphRelocationManager to stop as soon as possible.

Constructor Detail

SubgraphRelocationManager

public SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager)

Create a new SubgraphRelocationManager with the specified subgraph GraphLayoutManager, default subgraph padding and (perhaps initially) no GraphRenderer.

SubgraphRelocationManager

public SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager,
                                 GraphRenderer renderer)

Create a new SubgraphRelocationManager with the specified subgraph GraphLayoutManager and GraphRenderer and with default subgraph padding.

SubgraphRelocationManager

public SubgraphRelocationManager(GraphLayoutManager subgraphLayoutManager,
                                 GraphRenderer renderer,
                                 double subgraphPadding)

Create a new SubgraphRelocationManager calculating layouts using the specified subgraph GraphLayoutManager, GraphRenderer and subgraph padding. The GraphRenderer may be null, in which case the bounding box in layout space is used.

Method Detail

setSubgraphLayoutManager

public void setSubgraphLayoutManager(GraphLayoutManager subgraphLayoutManager)

getSubgraphLayoutManager

public GraphLayoutManager getSubgraphLayoutManager()

setGraphRenderer

public void setGraphRenderer(GraphRenderer renderer)

getGraphRenderer

public GraphRenderer getGraphRenderer()

setSubgraphPadding

public void setSubgraphPadding(double subgraphPadding)

getSubgraphPadding

public double getSubgraphPadding()

setBaselineInterval

public void setBaselineInterval(int baselineInterval)

getBaselineInterval

public int getBaselineInterval()

createLayoutConverter

public LayoutConverter createLayoutConverter()

This method passes the invocation to the subgraph layout manager, and returns 'null' when there is none.

Specified by:

createLayoutConverter in class GraphLayoutManager

initialize

public void initialize(Graph graph)

Invokes the initialize method of the subgraph GraphLayoutManager.

Specified by:

initialize in class GraphLayoutManager

doLayout

public void doLayout()

Calculates a layout for the complete Graph registered in this SubgraphRelocationManager.

Specified by:

doLayout in class GraphLayoutManager

stop

public void stop()

Sets a flag that will cause the SubgraphRelocationManager to stop as soon as possible. The various global starting and finished events (i.e. the events that do not refer to a single subgraph) are still send.

addSubgraphRelocationListener

public void addSubgraphRelocationListener(SubgraphRelocationListener listener)

Add a SubgraphRelocationListener to this SubgraphRelocationManager.

removeSubgraphRelocationListener

public void removeSubgraphRelocationListener(SubgraphRelocationListener listener)

Remove a SubgraphRelocationListener from this SubgraphRelocationManager.
