Now we will change the body of the java method so that it uses the body attribute
of the operation. In the case where body is empty, we will provide a default implementation.
The first step is to define a defaultMethodBody TGL script on Operation which will return null
if the operation has a return type, or return an empty string.

[#script public defaultMethodBody]
[#if self.hasReturnType]
return null;
[/#if]
[/#script]
We then need to create a methodBody MQL Script on Operation that will call the
defaultMethodBody script.

public script methodBody() : String {
if (self.body.length() > 0) {
return self.body;
} else {
return self.defaultMethodBody();
}
}
The methodBody script is now called from the declaration script on Operation.
[#package tutorial.java]
[#metatype rhapsody.Operation]
[#script public declaration]
public ${self.returnType} ${self.name}() {
${self.methodBody}[#ltrim]
}
[/#script]
Relaunch the generation and open the file Order.java:
public class Order {
private RhpString date;
private Customer customer;
private java.util.Collection items;
public LineItem findLineItem(RhpString productName) {
return null;
}
}
