public class IlvHyperEdgeCenterConnector
extends IlvHyperEdgeConnectorWithCache

The hyperedge center connector connects the hyperedge ends to the center of the corresponding nodes. This connector can be attached to a node or to a hyperedge (see IlvHyperEdgeConnector.attach(ilog.views.IlvGraphic, boolean)). This connector does not display any visible part, therefore it does not act like a graphic object and should never be added to a grapher. It is purely a computation mechanism.

Since:

JViews 8.0

Constructor Detail

IlvHyperEdgeCenterConnector

public IlvHyperEdgeCenterConnector()

Creates an empty IlvHyperEdgeCenterConnector. To attach the connector to a node or hyperedge, call IlvHyperEdgeConnector.attach(ilog.views.IlvGraphic, boolean).

IlvHyperEdgeCenterConnector

public IlvHyperEdgeCenterConnector(boolean fullyZoomable)

Creates an empty IlvHyperEdgeCenterConnector. To attach the connector to a node or hyperedge, call IlvHyperEdgeConnector.attach(ilog.views.IlvGraphic, boolean).

The parameter fullyZoomable controls whether the connector behaves fully zoomable. If true, the connector zooms the center point relative to the center point of the unzoomed bounding box of the end nodes. For some graphic objects such as IlvHalfZoomingGraphic, the zoomed center point of a node might in this case differ from the connection point calculated by this connector. However, it works for most zoomable graphic objects and it is in general faster. If false, the connector calculates the center point of end nodes from the zoomed bounding box. The center point matches in this case the connection point perfectly, but the connector has eventually no zoomable connections, i.e. connectionsZoomable() returns false.

IlvHyperEdgeCenterConnector

public IlvHyperEdgeCenterConnector(IlvGraphic obj)

Creates an IlvHyperEdgeCenterConnector attached to the input object, which can be a node or a hyperedge.

IlvHyperEdgeCenterConnector

public IlvHyperEdgeCenterConnector(IlvHyperEdgeCenterConnector source)

Creates an IlvHyperEdgeCenterConnector by copying an existing one.

Parameters:

source - The origin of the copy.

IlvHyperEdgeCenterConnector

public IlvHyperEdgeCenterConnector(IlvInputStream stream)
                            throws IlvReadFileException

Reads the object from an IlvInputStream.

Parameters:

stream - The input stream.

Throws:

IlvReadFileException - if the format is not correct.

Method Detail

write

public void write(IlvOutputStream stream)
           throws IOException

Writes the object to an IlvOutputStream. You should not call this method directly; instead, you should use the write methods of the manager.

Specified by:

write in interface IlvPersistentObject

Overrides:

write in class IlvHyperEdgeConnector

Parameters:

stream - The output stream.

Throws:

IOException - thrown when an exception occurs during the write operation for this object.

copy

public IlvGraphic copy()

Copies the object.

Specified by:

copy in class IlvGraphic

Returns:

A copy of the object.

See Also:

IlvGraphic

isGraphic

public boolean isGraphic()

Returns whether the connector displays a visible part. This connector never displays any visible part, therefore it always returns false.

Overrides:

isGraphic in class IlvHyperEdgeConnector

calcConnectionPoint

protected IlvPoint calcConnectionPoint(IlvHyperEdgeEnd end,
                                       IlvTransformer t)

Calculate the connection point of the hyperedge end at the corresponding node. This method cannot look up in the cache. It is used to fill the cache.

Specified by:

calcConnectionPoint in class IlvHyperEdgeConnectorWithCache

Parameters:

end - The hyperedge end.

t - The transformer used to draw the hyperedge.

Returns:

The connection point at the node in view coordinates

getClosestConnectionPoint

public IlvPoint getClosestConnectionPoint(IlvHyperEdgeEnd end,
                                          IlvPoint p,
                                          IlvTransformer t)

Returns the closest possible connection point of the hyperedge end at the corresponding node.

Specified by:

getClosestConnectionPoint in class IlvHyperEdgeConnector

Parameters:

end - The hyperedge end.

p - The proposed point in view coordinates.

t - The transformer used to draw the hyperedge.

Returns:

The center point of the node in view coordinates.

connectionsZoomable

public boolean connectionsZoomable()

Returns true if the connection points of the hyperedge at zoomable nodes are zoomable. A connection point is zoomable if calling the method IlvHyperEdgeConnectorWithCache.getConnectionPoint(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvTransformer) with a transformer gives the same result as calling it with a null (identity) transformer and then applying the transformer to the result. This is only tested if the hyperedge end is attached to a zoomable node.

Note that an instance of a hyperedge connector must return the same value as long as it is attached to the same object.

Don't confuse this with the method IlvHyperEdgeConnector.zoomable() which indicates whether the connector as graphic object would be zoomable.

Overrides:

connectionsZoomable in class IlvHyperEdgeConnector
