To extend a predefined business class dynamically, you can create a
new instance of
IlpDefaultClass
from an XML description of the class.
The following example demonstrates how to
create a subclass of a predefined business class in XML.
How to create a subclass of a predefined business class in XML
<class>
<name>Element</name>
<superClass>ilog.tgo.model.IltNetworkElement</superClass>
<attribute>
<name>throughput</name>
<javaClass>java.lang.Integer</javaClass>
</attribute>
</class>
The syntax is the same as for creating a regular class with XML.
See Defining the business model in XML.
The newly created class extends the IltNetworkElement predefined business class
and has an additional attribute (
throughput
).
This class is an instance of both the
IlpClass
Element
and the Java™ class
ilog.tgo.model.IltNetworkElement
.
As shown in the following figure, an instance of
Element
derives from two class hierarchies: the dynamic class hierarchy
and the Java class hierarchy.
Deriving instances from the dynamic
and the Java class hierarchies
If you create an instance of the
IlpClass
Element
with XML, the created object will be an instance of the Java
class IltNetworkElement.
