public class IlvSimpleLink extends IlvEnhancedPolylineLinkImage
IlvEnhancedPolylineLinkImage
.
Additionally, it allows the registering of property change listeners on the
link. These listeners get notified whenever a property of the link changes.
The link can have a forward arrow and a backward arrow. The link has various options that control the link shape. The link can automatically stay orthogonal, that is, with a shape comprising a sequence of horizontal and vertical segments. The link can also show crossings between orthogonal segments of other links of the same type by a tunnel or bridge shape. These crossing shapes are particularly appropriate if the line style is solid, but may be aesthetically less pleasing if the line style of the link is dashed.
This link is suitable for use with graph layout. Orthogonal links must be connected to free link connectors or clipping link connectors.
