Field Detail

INSTANCE

public static EcoreEnvironmentFactory INSTANCE

A convenient shared instance of the environment factory, that creates environments using the global package registry.

Constructor Detail

EcoreEnvironmentFactory

public EcoreEnvironmentFactory()

Initializes me. Environments that I create will use the global package registry to look up packages.

EcoreEnvironmentFactory

public EcoreEnvironmentFactory(org.eclipse.emf.ecore.EPackage.Registry reg)

Initializes me with an EPackage.Registry that the environments I create will use to look up packages.

Parameters:

reg - my package registry (must not be null). Package descriptors that are not yet resolved will not be resolved for OCL package name lookups. To ensure that packages can be referenced by their name, clients shall resolve those packages explicitly before asking OCL to look them up. See also ParsingOptions.PACKAGE_LOOKUP_STRATEGY for different package lookup strategies. Note also, that if a "delegating registry" is used, packages contained only by the delegate will not be found by an OCL lookup because EPackage.Registry#values() only enumerates the packages / descriptors contained by the outer registry.

Method Detail

createEnvironment

public Environment<org.eclipse.emf.ecore.EPackage,org.eclipse.emf.ecore.EClassifier,org.eclipse.emf.ecore.EOperation,org.eclipse.emf.ecore.EStructuralFeature,org.eclipse.emf.ecore.EEnumLiteral,org.eclipse.emf.ecore.EParameter,org.eclipse.emf.ecore.EObject,CallOperationAction,SendSignalAction,Constraint,org.eclipse.emf.ecore.EClass,org.eclipse.emf.ecore.EObject> createEnvironment()

Description copied from interface: EnvironmentFactory

Creates a root environment, in which package contexts and/or classifier contexts will be created as nested environments. All operation body constraints, attribute initial/derived value constraints, and definitions of additional attributes and operations should be maintained by the root environment, so that they will be accessible from constraints parsed in any nested environment.

Returns:

a new root environment

loadEnvironment

public Environment<org.eclipse.emf.ecore.EPackage,org.eclipse.emf.ecore.EClassifier,org.eclipse.emf.ecore.EOperation,org.eclipse.emf.ecore.EStructuralFeature,org.eclipse.emf.ecore.EEnumLiteral,org.eclipse.emf.ecore.EParameter,org.eclipse.emf.ecore.EObject,CallOperationAction,SendSignalAction,Constraint,org.eclipse.emf.ecore.EClass,org.eclipse.emf.ecore.EObject> loadEnvironment(org.eclipse.emf.ecore.resource.Resource resource)

Description copied from interface: EnvironmentFactory

Loads an environment from the specified resource. If not already loaded, this method will load the resource. This resource will subsequently be used to persist new OCL constraints, so supplying a new, empty resource will allow the client to determine where the environment is persisted.

Parameters:

resource - a resource containing the persisted environment

getEPackageRegistry

public final org.eclipse.emf.ecore.EPackage.Registry getEPackageRegistry()

Obtains the package registry used by environment that I create to look up packages.

Returns:

my package registry

lookupPackage

protected org.eclipse.emf.ecore.EPackage lookupPackage(java.util.List<java.lang.String> pathname)

Description copied from class: AbstractEnvironmentFactory

Looks up the package identified by the specified qualified name by whatever means is appropriate to the particular environment implementation.

Specified by:

lookupPackage in class AbstractEnvironmentFactory<org.eclipse.emf.ecore.EPackage,org.eclipse.emf.ecore.EClassifier,org.eclipse.emf.ecore.EOperation,org.eclipse.emf.ecore.EStructuralFeature,org.eclipse.emf.ecore.EEnumLiteral,org.eclipse.emf.ecore.EParameter,org.eclipse.emf.ecore.EObject,CallOperationAction,SendSignalAction,Constraint,org.eclipse.emf.ecore.EClass,org.eclipse.emf.ecore.EObject>

Parameters:

pathname - the qualified name of the package to find

Returns:

the matching package, or null if none is found

getClassifier

protected org.eclipse.emf.ecore.EClassifier getClassifier(java.lang.Object context)

Description copied from class: AbstractEnvironmentFactory

Obtains client metamodel's classifier for the specified context object, which may be an instance of a classifier in the user model or may actually be a classifier in the user model.

Specified by:
