public class IlvHyperEdgeFixedConnector
extends IlvHyperEdgeConnectorWithCache

The hyperedge fixed connector connects the hyperedge ends to any point at the corresponding node. To change the connection point, call IlvHyperEdgeConnector.connect(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvPoint, ilog.views.IlvTransformer). However, the connection points are interactively not movable. 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

IlvHyperEdgeFixedConnector

public IlvHyperEdgeFixedConnector()

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

IlvHyperEdgeFixedConnector

public IlvHyperEdgeFixedConnector(IlvGraphic obj)

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

IlvHyperEdgeFixedConnector

public IlvHyperEdgeFixedConnector(IlvHyperEdgeFixedConnector source)

Creates an IlvHyperEdgeFixedConnector by copying an existing one.

Parameters:

source - The origin of the copy.

IlvHyperEdgeFixedConnector

public IlvHyperEdgeFixedConnector(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

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:

Always a copy of the proposed point.

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
