Performing the forward engineering

The example shows how to perform a simple java code generation.

Step #1. Creating CodeEngineeringSet

    Project project = Application.getInstance().getProject(); 
    String name = "sample CE project";
    String workingDir = OPENAPI_DATA_DIRECTORY_PATH;
 
    // create a working package
    ElementsFactory ef = project.getElementsFactory();
    Package workingPackage = ef.createPackageInstance();
    workingPackage.setName("my working package");
    workingPackage.setOwner(project.getModel());
 
    // creating a code engineering set
    CodeEngineeringSet javaGenerationSet = CodeEngineeringManager.createCodeEngineeringSet(
				CodeEngineeringConstants.Languages.JAVA, null, name, project, workingPackage, workingDir);

Step #2. Adding model elements to CodeEngineeringSet

	Project project = Application.getInstance().getProject();
 
 	// create a new element
 	ElementsFactory ef = project.getElementsFactory();
 	Class classA = ef.createClassInstance();
 	classA.setName("ClassA");
	classA.setOwner(project.getModel());
	List<BaseElement> modelsForSample = new ArrayList<BaseElement>();
	modelsForSample.add(classA);
	javaGenerationSet.addElementsToCodeEngineeringSet(modelsForSample);
Step #3. Performing the CodeEngineeringSet generation
    CodeEngineeringManager.generate(javaGenerationSet);

Performing the reverse engineering

The example shows how to perform a simple java code reverse.

Step #1. Creating CodeEngineeringSet

    Project project = Application.getInstance().getProject(); 
    String name = "sample CE project";
    String workingDir = OPENAPI_DATA_DIRECTORY_PATH;// e.g C:\myworkingPackage
 
    // create a working package
    ElementsFactory ef = project.getElementsFactory();
    Package workingPackage = ef.createPackageInstance();
    workingPackage.setName("my working package");
    workingPackage.setOwner(project.getModel());
 
    // creating a code engineering set
    CodeEngineeringSet ces = CodeEngineeringManager.createCodeEngineeringSet(
				CodeEngineeringConstants.Languages.JAVA, null, name, project, workingPackage, workingDir);

Here the null dialect is used for the java language, because java doesn't have any dialect.

Step #2. Adding the source code to CodeEngineeringSet

 	ces.addAllFilesRecursivelyToCES(new File(workingDir + File.separator + "test directory")); // starting from C:\myworkingPackage\test directory\

This sets the given instance of the code engineering set working directory and adds all files from that directory. Set java classpaths for the project:

    String[] claspath = new String[] { path1, path2, path3, path4 }; 
    JavaCodeEngineeringManager.setJavaClasspath(project, claspath);

Step #3. Performing the reverse of CodeEngineeringSet

     CodeEngineeringManager.reverse(ces, false);
