Constructor Detail

IlvSDMFreeLinkConnector

public IlvSDMFreeLinkConnector(IlvLinkImage link,
                               boolean origin)

Creates a new SDM free link connector.

Parameters:

link - The link to which the connector is attached.

origin - true creates a link connector for the origin.

IlvSDMFreeLinkConnector

public IlvSDMFreeLinkConnector(IlvGraphic node,
                               IlvSDMEngine engine)

Creates a new SDM free link connector.

Parameters:

node - The node to which the connector is attached.

engine - The SDM engine in which the link connector is used.

Since:

JViews 6.5

IlvSDMFreeLinkConnector

public IlvSDMFreeLinkConnector(IlvGraphic node)

Creates a new SDM free link connector.

Parameters:

node - The node to which the connector is attached.

IlvSDMFreeLinkConnector

public IlvSDMFreeLinkConnector()

Creates a new SDM free link connector.

IlvSDMFreeLinkConnector

public IlvSDMFreeLinkConnector(IlvInputStream stream)
                        throws IlvReadFileException

Reads an SDM free link connector from an IVL input stream.

Parameters:

stream - The IVL input stream.

Throws:

IlvReadFileException - if the format is not correct.

Method Detail

useCache

protected boolean useCache()

Return true because this link connector uses the cache.

Overrides:

useCache in class IlvFreeLinkConnector

Since:

JViews 8.7

getNodeBoundingBox

protected IlvRect getNodeBoundingBox(IlvTransformer t)

This method is overridden to take into account the link connection rectangle of the node. It calls the method getLinkConnectionRectangle of the SDM renderer(s).

Overrides:

getNodeBoundingBox in class IlvFreeLinkConnector

Parameters:

t - The transformer used to compute the link connection rectangle of the node.

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 IlvFreeLinkConnector

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.

getEngine

public IlvSDMEngine getEngine()

Returns the SDM Engine using this link connector.

Since:

JViews 8.1
