public class IlpLinkLayoutRenderer
extends ilog.cpl.graph.css.renderer.IlpLinkLayoutRenderer
IlpNetworkView
.
This class is a CSS stylable Bean. It can be configured like this in a CSS file:
LinkLayout { class: "ilog.tgo.graphic.graphlayout.IltShortLinkLayout"; // Any properties configurable for given class. }
The value of the class
property should be the name of a
subclass of IlvGraphLayout
that has a
no-argument constructor.
The allowed properties and their values depend on the class
.
The properties linkLayout
can be set on a subgraph node.
This lets you use a different link layout algorithm for each subgraph.
For example, the following rule says that subgraph identified as
SubNetwork1
must be laid out using an
IlvLinkLayout
algorithm:
#SubNetwork1:linkLayoutRenderer { linkLayout: @+linkLayout; } Subobject#linkLayout { class: 'ilog.views.graphlayout.link.IlvLinkLayout'; // Any properties configurable for given class. }
When specifying the link layout for a given subnetwork, use the pseudoclass linkLayoutRenderer indicating that the properties refers to the link layout renderer.
Rogue Wave JViews layout algorithms (that is, subclasses of
IlvGraphLayout
) provide many parameters
that control how a specific layout will be applied to a particular node
or link. Starting with JTGO 7.5, the link layout renderer lets you
set these per-object parameters from the style sheet as in the following
examples:
object."ilog.tgo.model.IltAbstractLink":linkLayoutRenderer:link { linkStyle: DIRECT_STYLE; }
The first rule will cause the method
IlvLinkLayout.setLinkStyle(java.lang.Object, int)
to be called for all the links that match the rule.
Note: Starting with JTGO 7.5, if you are not using any node
or link parameters, you can disable this mechanism using
setUsePerObjectParameters(false)
.
This will remove the overhead of testing the parameters, which can speed up
the rendering process significantly.

public void setUsePerObjectParameters(boolean use)
This method can be used to disable or re-enable the mechanism that sets per-link parameters, as explained in the class description.
By default, per-object parameters are enabled. You can disable them if you are sure that your style sheet does not use any per-object layout parameters. Disabling per-object parameters speeds up the rendering process.

- If this parameter is true
, per-object
layout parameters can be set in the style sheet, as explained
in the class description. If this parameter is false
,
per-object layout parameters are ignored.© Copyright Rogue Wave Software, Inc. 1997, 2018. All Rights Reserved.
