ClassSupplier

ClassSupplier is the Eclipse plug-in allowing to make code programmatically.

It generates, builds, installs and loads the entire plug-in with the Java classes that conform the reflective model provided and are accessible through that API.

Example:

// Model EMF EPackage
EPackage modelEPackage = EcoreFactory.eINSTANCE.createEPackage();
modelEPackage.setName("library");
modelEPackage.setNsPrefix("library");
modelEPackage.setNsURI("http://library/1.0");
EClass eClass = EcoreFactory.eINSTANCE.createEClass();
eClass.setName("Book");
EAttribute eAttr = EcoreFactory.eINSTANCE.createEAttribute();
eAttr.setName("pages");
eAttr.setEType(EcorePackage.Literals.EINT);
eClass.getEStructuralFeatures().add(eAttr);
modelEPackage.getEClassifiers().add(eClass);

// Acquire ClassSupplier OSGi service
BundleContext bundleContext = FrameworkUtil.getBundle(this.getClass())
                            .getBundleContext();
ServiceReference<?> serviceReference = bundleContext
                          .getServiceReference(ClassSupplier.class);
ClassSupplier classupplier = (ClassSupplier) bundleContext
                          .getService(serviceReference);

// Combine them
Contribution contribution = classupplier.getWorkspace().createContribution(
                          modelEPackage);
Future<? extends EPackage> result = contribution
                          .construct(new NullProgressMonitor());
EPackage ePackage = result.get();

// Use the runtime
EClass jClass = (EClass) ePackage.getEClassifier(eClass.getName());
EObject jObject = ePackage.getEFactoryInstance().create(jClass); 
int pages = 500;
EStructuralFeature jAttr = jClass.getEStructuralFeature(eAttr
    .getName());
jObject.eSet(jAttr, pages);
assertEquals(pages, jObject.eGet(jAttr));
assertEquals(eClass.getName(), jObject.getClass().getSimpleName());

Here is an example.
