| <h2 id="Java_Generation">Java Generation</h2> |
| <p>The goal of the Java Generation plug-in is to allow Java code generation from a Java model. Such a generation will fulfill some of the requirements for Legacy refactoring and migration. </p> |
| <p> |
| <i>Quality disclaimer: this generator is provided without any guarantee.</i> |

| </p> |
| <p>This plug-in proposes Acceleo modules for generating Java files conforming to Java models. Templates are contained in two modules </p> |
| <ul> |
| <li>Structures modules top level templates for generating classes/method/field declarations </li> |
| <li>Statements modules</li> |
| </ul> |
| <p>Java models are obtained with the |
| <a href="../java_discoverer/user.html">Java Discoverer</a> component. |
| </p> |
| <p>Considering a Java legacy, a minimal migration/refactoring chain will involve </p> |
| <ul> |
| <li>A Java model discovery step </li> |
| <li>A M2M transformation step </li> |
| <li>A Java generation code step with the current component</li> |
| </ul> |
| <h3 id="User_manual">User manual</h3> |
| <p>A prerequisite is a Java model. Please refer to the |
| <a href="../java_discoverer/user.html"> Java Discoverer</a> user manual. |
| </p> |
| <p>To launch a Java generation, add |
| <i>org.eclipse.modisco.java.generation</i> in your plugin dependencies and use the |
| <i>GenerateJavaExtended</i> main method with input model and target folder as parameters. The code should look like this : |
| </p> |
| <pre> |
| GenerateJavaExtended javaGenerator = new GenerateJavaExtended(URI.createFileURI("C:/.../my.javaxmi"), |
| new File("C:/.../myOutputFolder"), new ArrayList<Object>()); |
| javaGenerator.doGenerate(null); |
| </pre> |
| <p>Note : at the moment this documentation is written, there is no way of creating one Acceleo Launch Configuration based on one installed Acceleo module plugin.</p> |
