Constructor and Description
IlvDashboardLinkConnector() Constructs an instance of IlvDashboardLinkConnector, to be used by the CSS mechanism.

Method Summary

Modifier and Type	Method and Description
boolean	allowsConnectionPointMove(IlvLinkImage link, boolean origin) This implementation always returns true so the link connection point can be moved by interactors.
protected IlvPoint	calcConnectionPoint(IlvLinkImage link, boolean origin, IlvTransformer transformer) This method is overridden to take into account the link connection rectangle of the node.
void	connectLink(IlvLinkImage link, IlvPoint p, boolean origin, IlvTransformer t) Connects a link to a specified connection point.
protected boolean	useCache() Return false because this link connector uses no cache.

Constructor Detail

IlvDashboardLinkConnector

public IlvDashboardLinkConnector()

Constructs an instance of IlvDashboardLinkConnector, to be used by the CSS mechanism.

Method Detail

useCache

protected boolean useCache()

Return false because this link connector uses no cache.

Overrides:

useCache in class IlvSDMFreeLinkConnector

allowsConnectionPointMove

public boolean allowsConnectionPointMove(IlvLinkImage link,
                                         boolean origin)

This implementation always returns true so the link connection point can be moved by interactors.

Overrides:

allowsConnectionPointMove in class IlvFreeLinkConnector

Returns:

true

See Also:

IlvFreeLinkConnector.connectionPointMoveAllowed(boolean), IlvLinkImage.allowsPointMove(int), IlvFreeLinkConnector.isConnectionPointMoveAllowed()

connectLink

public void connectLink(IlvLinkImage link,
                        IlvPoint p,
                        boolean origin,
                        IlvTransformer t)

Connects a link to a specified connection point.

Notice that, for links that have not been connected using IlvFreeLinkConnector.connectLink(ilog.views.IlvLinkImage, ilog.views.IlvPoint, boolean, ilog.views.IlvTransformer) and for disconnected links (see IlvFreeLinkConnector.disconnectLink(ilog.views.IlvLinkImage, boolean) and IlvFreeLinkConnector.disconnectAllLinks()), the method IlvCachingLinkConnector.getConnectionPoint(ilog.views.IlvLinkImage, boolean, ilog.views.IlvTransformer) returns null. In this case, IlvLinkImage computes the connection point of the link using the default rules, at the center of one of the sides of the bounding box of the node or at its center.

Note also that, once a link connector has been attached to a node or a link contained in an IlvGrapher, this method must be called using the method IlvManager.applyToObject(ilog.views.IlvGraphic, ilog.views.IlvApplyObject, java.lang.Object, boolean).

Overrides:

connectLink in class IlvFreeLinkConnector

Parameters:

link - The link to be connected.

p - The point where the link must be connected. The point must be transformed by transformer t.

origin - If true, the origin of the link will be connected. Otherwise, it is the destination.

t - The transformer that is used to draw the node.

IlvFreeLinkConnector.disconnectLink(ilog.views.IlvLinkImage, boolean), IlvFreeLinkConnector.disconnectAllLinks()

calcConnectionPoint

protected IlvPoint calcConnectionPoint(IlvLinkImage link,
                                       boolean origin,
                                       IlvTransformer transformer)

This method is overridden to take into account the link connection rectangle of the node.

Overrides:

calcConnectionPoint in class IlvSDMFreeLinkConnector

Parameters:

link - The link.

origin - If true, the position of the link connection point for the link origin is determined. Otherwise, the position of the link connection point for the link destination is found.

transformer - The transformer that is used to draw the node.
