getStates

public java.util.List<org.eclipse.emf.ecore.EObject> getStates(org.eclipse.emf.ecore.EClassifier owner,

Obtains the states matching the specified path prefix in the owner type by trying the collectStates(org.eclipse.emf.ecore.EClassifier, java.util.List, java.util.List) method on it and, recursively, its supertypes to find all matches. For implicit (null) owners, looks up the innermost-scoped variable as the implicit source and tries again on this variable's type.

To extend this implementation, override the collectStates(org.eclipse.emf.ecore.EClassifier, java.util.List, java.util.List) method.

Specified by:

getStates in interface 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>

Parameters:

owner - the classifier for which states are being sought. Can be null in the case of an oclIsInState() call on an implicit target

pathPrefix - partial path name of the states being sought. This can be empty to find the first level of state names

Returns:

the list of all possible states directly contained in the namespace indicated by the path prefix (i.e., only one level of state nesting)

collectStates

protected void collectStates(org.eclipse.emf.ecore.EClassifier owner,

Implemented by subclasses to find all states in the specified owner type that match the given path name prefix and add them to the accumulator list. The default implementation does nothing, as Ecore does not model states.

Implementors must only provide the states defined directly in the namespace indicated by the path prefix (i.e., only one level).

Parameters:

owner - the owner type

pathPrefix - partial qualified name, specifying the parent of the states to be collection

states - a list of states directly owned by the namespace indicated by path prefix, within the owner type

owner - the context classifier of the property definition constraint

name - the operation name

params - the names and types of the parameters, if any (conveniently encapsulated in variables)

constraint - the definition constraint

Returns:

the defined operation

                                                           throws LookupException

This default implementation simply delegates to the Environment#lookupOppositeProperty(Object, String) method.

Throws:

tryLookupProperty

public org.eclipse.emf.ecore.EStructuralFeature tryLookupProperty(org.eclipse.emf.ecore.EClassifier owner,

                                                           throws LookupException

This default implementation simply delegates to the Environment.lookupProperty(Object, String) method.

Specified by:

tryLookupProperty in interface Environment.Lookup<org.eclipse.emf.ecore.EPackage,org.eclipse.emf.ecore.EClassifier,org.eclipse.emf.ecore.EOperation,org.eclipse.emf.ecore.EStructuralFeature>

Overrides:

tryLookupProperty in class AbstractEnvironment<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:

findOppositeEnds

protected void findOppositeEnds(org.eclipse.emf.ecore.EClassifier classifier,
                                java.lang.String name,
                                java.util.List<org.eclipse.emf.ecore.EReference> ends)

Searches for non-navigable association ends with the specified name at the given classifier's end of an association. Subclasses should reimplement this method if they support non-navigable association ends.

Parameters:

classifier - a classifier at an association end

name - the non-navigable end name to look for

ends - collects the ends found by the subclass implementation

Since:

3.1

findNonNavigableAssociationEnds

protected void findNonNavigableAssociationEnds(org.eclipse.emf.ecore.EClassifier classifier,
                                               java.lang.String name,
                                               java.util.List<org.eclipse.emf.ecore.EStructuralFeature> ends)

If a "hidden" opposite is found (because a forward reference has a "Property.oppositeRoleName" annotation specifying a name for the opposite role), this method adds a temporary EReference to the ends list which has no container set and as its opposite uses the forward reference. The name of this temporary reference is set to name which equals the value of the "Property.oppositeRoleName" annotation on the forward reference.

The temporary reference is not a valid reference for at least two reasons: its container is not set and its opposite does not name it as its opposite.

Overrides:

findNonNavigableAssociationEnds in class AbstractEnvironment<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:

classifier - a classifier at an association end

name - the non-navigable end name to look for

ends - collects the ends found by the subclass implementation
