| Implementation of an OCL binding for the <tt>Ecore</tt> metamodel. |
| |
| <h2>Package Specification</h2> |
| <p> |
| This package defines an OCL {@linkplain org.eclipse.ocl.Environment environment} |
| implementation for the <tt>Ecore</tt> metamodel. Clients can use an |
| {@link org.eclipse.ocl.ecore.EcoreEnvironmentFactory} in conjunction with the |
| {@link org.eclipse.ocl.ecore.OCL} class to parse and evaluated OCL constraints |
| on Ecore models. |
| </p> |
| </p> |
| Clients may extend the environment implementation to support custom requirements, |
| such as overriding the |
| {@link org.eclipse.ocl.Environment#lookupOperation} and |
| {@link org.eclipse.ocl.EvaluationEnvironment#callOperation} |
| methods to inject custom operations into existing metaclasses (to provide |
| Java implementations, rather than defining additional operations using OCL). |
| </p> |
| <p> |
| This package also extends the types of the OCL {@link org.eclipse.ocl.types Types} |
| package to define the generalization relationships to the Ecore metamodel's |
| counterparts to the UML Classifier ({@link org.eclipse.emf.ecore.EClassifier}) |
| and DataType ({@link org.eclipse.emf.ecore.EDataType}) metaclasses. This |
| ensures a consistent type system in the OCL binding for Ecore, so that all |
| types are represented as <tt>EClassifier</tt>s. |
| </p> |
| <p> |
| Clients may assume that any types referenced by OCL constraints parsed against |
| an Ecore model are instances of the interfaces in this package. |
| </p> |
