Modify the Design with Groovy Scripts

The designed classes can be modified from Groovy scripts. Here is an example of how to generate a version attribute with a @Version tag in all <<Persistent>> classes:

When the diagram is saved, this will generate Java code:

	@javax.persistence.Version
	public int getVersion() {
		return this.version;
	}

To modify classes of a specific stereotype, download the corresponding file, copy it into your project root directory and modify it as desired:

Stereotype	Groovy Script
`DAO`	DAOClassBuilder.groovy
`Java Bean`	JavaBeanClassBuilder.groovy
`Persistent`	PersistentClassBuilder.groovy
`Persistent Test`	PersistentTestClassBuilder.groovy
`Unit Test`	UnitTestClassBuilder.groovy
`GWT Service`	GWTServiceClassBuilder.groovy

When you update the script, you can see the changes immediately in the class diagram. Then, save the diagram to regenerate the Java code.

The script has a two methods build and clear that are called as follows:

When the script is first created, build is called.
When the script is modified, clear in the old script is called first, and then build in the new script.
When the script is deleted, clear is called.
Whenever an input value to the build method is modified, build is called immediately. For instance, if build calls findVariablesWithStereotype(...), c.getName(), or in Groovy syntax c.name, it will be called again if the output of those method changes.
