Constructor Detail

IlvHyperEdgeConnectorWithCache

public IlvHyperEdgeConnectorWithCache()

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

IlvHyperEdgeConnectorWithCache

public IlvHyperEdgeConnectorWithCache(IlvGraphic obj)

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

IlvHyperEdgeConnectorWithCache

public IlvHyperEdgeConnectorWithCache(IlvHyperEdgeConnectorWithCache source)

Creates an IlvHyperEdgeConnectorWithCache by copying an existing one.

Parameters:

source - The origin of the copy.

IlvHyperEdgeConnectorWithCache

public IlvHyperEdgeConnectorWithCache(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

detachImpl

protected void detachImpl()

This method is called inside IlvHyperEdgeConnector.detach(boolean) to detach the connector from the node or hyperedge. You should not call this. You can override this method in order to perform additional operations for specific subclasses of IlvHyperEdgeConnector.

Overrides:

detachImpl in class IlvHyperEdgeConnector

actOnOwnerInserted

public void actOnOwnerInserted(IlvGraphic nodeOrEdge,
                               boolean redraw)

React when the node or hyperedge of this connector is inserted into a hypergrapher. You should not call this methods.

Overrides:

actOnOwnerInserted in class IlvHyperEdgeConnector

Parameters:

nodeOrEdge - The node or hyperedge the connector is attached to.

redraw - If true, the manager is redrawn.

actOnOwnerRemoved

public void actOnOwnerRemoved(IlvGraphic nodeOrEdge,
                              boolean redraw)

React before the node or hyperedge is removed from its manager. You should not call this methods.

Overrides:

actOnOwnerRemoved in class IlvHyperEdgeConnector

Parameters:

nodeOrEdge - The node or hyperedge the connector is attached to.

redraw - If true, the manager is redrawn.

disconnect

public boolean disconnect(IlvHyperEdgeEnd end)

Disconnect a hyperedge end from the hyperedge connector. This is called when the hyperedge end is removed from the hyperedge, so that the hyperedge is not anymore incident to the corresponding node. If the hyperedge is inside a grapher, this must be done inside an applyToObject session of the hyperedge that has the hyperedge end (see IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean)).

Overrides:

disconnect in class IlvHyperEdgeConnector

Parameters:

end - The hyperedge end.

Returns:

true if the end was connected, false otherwise.

See Also:

IlvHyperEdgeConnector.connect(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvPoint, ilog.views.IlvTransformer)

adjustAll

public void adjustAll()

Adjust all ends connected to the hyperedge connector. This is called when the node or hyperedge has moved. The default implementation calls adjust(ilog.views.hypergraph.IlvHyperEdgeEnd) with null proposed point and null transformer for all ends that are managed by this hyperedge connector.

Overrides:

adjustAll in class IlvHyperEdgeConnector

adjust

public void adjust(IlvHyperEdgeEnd end)

Adjusts one ends connected to the hyperedge connector. This is called when the node or hyperedge has moved. The default implementation calls IlvHyperEdgeEnd.positionChanged().

Overrides:

adjust in class IlvHyperEdgeConnector

getConnectionPoint

public IlvPoint getConnectionPoint(IlvHyperEdgeEnd end,
                                   IlvTransformer t)

Returns the connection point of the hyperedge end at the corresponding node. This method first looks up in the cache for connection points. If the point is not cached, it calls calcConnectionPoint(ilog.views.hypergraph.IlvHyperEdgeEnd, ilog.views.IlvTransformer) to calculate the connection point.

Specified by:

getConnectionPoint in class IlvHyperEdgeConnector

Parameters:

end - The hyperedge end.

t - The transformer used to draw the hyperedge.

Returns:

The connection point at the node in view coordinates

calcConnectionPoint

protected abstract 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.

Parameters:

end - The hyperedge end.

t - The transformer used to draw the hyperedge.

Returns:

The connection point at the node in view coordinates
