The group objects have been improved with the following new features:

Shortcut Representation

A shortcut group is an abstraction denoting an object that is only a reference to an existing group. IltGroup provides a new attribute, ShortcutAttribute, whose value can be:

A group can be defined as a shortcut by setting the value of attribute shortcut in the business object. This attribute can be set programmatically using IltGroup.ShortcutAttribute.

The following example illustrates how a group is created using this attribute via XML:

<addObject id="NE1">
  <class>ilog.tgo.model.IltGroup</class>
  <attribute name="name">Group1</attribute>
  <attribute name="shortcut">STANDARD</attribute>
  <attribute name="type">Group</attribute>
</addObject>

Shortcut groups are graphically represented by an icon located at the bottom left of the group plinth.

The result can be seen in the following image:

The shortcut representation is displayed according to the business object CSS configuration. The following properties can be used to customize the shortcut representation:

State Representation

The group representation (polygonal, rectangular or linear) now reflects the primary state information, if an object state has been set to the object.

The following image shows a polygonal group in different state representations corresponding to OSI primary states.

Like the other predefined business objects, you can customize groups according to their state information by using a CSS file. (See Customizing Groups in the Styling documentation.)

The new group representation is enabled through the CSS property baseStyleEnabled as shown in the following CSS extract:

object."ilog.tgo.model.IltGroup" {
  baseStyleEnabled: true;
}

Group Icon

It is now possible to customize an icon decoration for groups using CSS. The following properties are now supported:
