Thank you for your answer Glen. I missed this plugin in my search.
Though this plugin offers a lot of flexibility, it generates too much
code for my needs.
In the meantime, I tried to make my own plugin which appear to be
quite simple. As I was inspired by the cxf-xjc-ts plugin, I post it
here so anyone can use it :
package com.package;
import java.util.logging.Logger;
import org.xml.sax.*;
import com.sun.codemodel.*;
import com.sun.tools.xjc.*;
import com.sun.tools.xjc.outline.*;
/**
* @author Simon B.
*/
public class ToStringPlugin extends Plugin {
private static final Logger LOG =
Logger.getLogger(ToStringPlugin.class.getName());
private static final String NAME = "toString() XJC Plugin";
@Override
public String getOptionName() {
return "Xto-string";
}
@Override
public String getUsage() {
return "-Xto-string : Activate plugin to add a toString()
method to
generated classes.";
}
@Override
public boolean run(Outline outline, Options opt, ErrorHandler
errorHandler) throws SAXException {
LOG.fine("Running " + NAME + ".");
JClass guavaObjects =
outline.getCodeModel().ref("com.google.common.base.Objects");
for (ClassOutline co : outline.getClasses()) {
addToStringMethod(co, guavaObjects);
}
return true;
}
private void addToStringMethod(ClassOutline co, JClass guavaObjects) {
JDefinedClass implementation = co.implClass;
//
// Create toString() method
//
JMethod toStringMethod = implementation.method(JMod.PUBLIC,
String.class, "toString");
JDocComment doc = toStringMethod.javadoc();
doc.add("Generated by " + NAME);
toStringMethod.annotate(Override.class);
//
// return Objects.toStringHelper(this)
// .add("propertyName0", propertyValue0)
// ...
// .add("propertyNameN", propertyValueN)
// .toString();
//
JInvocation toStringHelperInvocation =
guavaObjects.staticInvoke("toStringHelper");
toStringHelperInvocation.arg(JExpr._this());
JInvocation lastAddInvocation = toStringHelperInvocation;
for (JFieldVar var : implementation.fields().values()) {
if (isStatic(var.mods()) == false) {
JInvocation addInvocation =
JExpr.invoke(lastAddInvocation, "add");
addInvocation.arg(JExpr.lit(var.name()));
addInvocation.arg(JExpr.ref(var.name()));
lastAddInvocation = addInvocation;
}
}
JInvocation toStringInvocation =
JExpr.invoke(lastAddInvocation, "toString");
toStringMethod.body()._return(toStringInvocation);
}
private static boolean isStatic(JMods mods) {
return (mods.getValue() & JMod.STATIC) != 0;
}
}
