Writing a XOM using Java-Like Syntax

PREVIOUS NEXT

You can write a XOM using a Java-like syntax.

To write a XOM:

  1. Use the classes in ilog.rules.bom.util .
    2. The classes in ilog.rules.bom.util provide the utilities used for loading such a file into an object model. Here is an example of a class specified using this syntax: 
package mypackage.binding;

 

public class Person

  extends ilog.rules.factory.IlrHashObject

  property "ilog.rules.engine.driver"

           "ilog.rules.factory.IlrHashDriver"

{

  public java.lang.String name;

  public int age;

  public Person();

}
  1. To read this class, create a reader with the above content.
  2. Use the following code to load the reader into the XOM: 
import ilog.rules.bom.util.*;

 

Reader reader = ...;

try

{

  new IlrJavaSerializer().readObjectModel(reflect,reader);

}

catch(IlrSyntaxError ex)

{

  // we have to process the syntax error

      String[] messages = error.getErrorMessages();

    for (int i = 0; i < messages.length; i++) {

      System.err.println(messages[i]);

    }

    System.err(error.getMessage());

}
