Method Detail

eAdd

public static <T> void eAdd(org.eclipse.emf.ecore.EObject object,
                            java.lang.String name,
                            T arg)
                 throws FactoryException

Adds the new value of the given feature of the object. If the structural feature isn't a list, it behaves like eSet.

Type Parameters:

T - Type of the new value to be added to the list.

Parameters:

object - Object on which we want to add to the feature values list.

name - The name of the feature to add to.

arg - New value to add to the feature values.

Throws:

FactoryException - Thrown if the affectation fails.

eAdd

public static <T> void eAdd(org.eclipse.emf.ecore.EObject object,
                            java.lang.String name,
                            T arg,
                            int elementIndex)
                 throws FactoryException

Adds the new value of the given feature of the object. If the structural feature isn't a list, it behaves like eSet.

Type Parameters:

T - Type of the new value to be added to the list.

Parameters:

object - Object on which we want to add to the feature values list.

name - The name of the feature to add to.

arg - New value to add to the feature values.

elementIndex - in case the feature is multiplicity-many, specify the index where the new value has to be added. If the index is -1, the value will be appended to the feature list.

Throws:

FactoryException - Thrown if the affectation fails.

eInsertAt

public static <T> void eInsertAt(org.eclipse.emf.ecore.EObject object,
                                 java.lang.String name,
                                 T arg,
                                 int insertionIndex)
                      throws FactoryException

Adds the new value of the given feature of the object at the given index. If the structural feature isn't a list, it behaves like eSet and the index is ignored.

Type Parameters:

T - Type of the new value to be added to the list.

Parameters:

object - Object on which we want to add to the feature values list.

name - The name of the feature to add to.

arg - New value to add to the feature values.

insertionIndex - Index in the list at which the new value is to be added.

Throws:

FactoryException - Thrown if the affectation fails.

                                    java.lang.String name)
                             throws FactoryException

Gets the value of the given feature of the object.

Parameters:

object - Object to retrieve the feature value from.

name - The feature name, or a method defined on EObject like 'eClass', 'eResource', 'eContainer', 'eContainingFeature', 'eContainmentFeature', 'eContents', 'eAllContents', 'eCrossReferences'

Returns:

Value of the given feature of the object

Throws:

FactoryException - Thrown if the retrieval fails.

eGetAsList

public static java.util.List<?> eGetAsList(org.eclipse.emf.ecore.EObject object,
                                           java.lang.String name)
                                    throws FactoryException

Gets the value of the given feature of the object as a List.

Parameters:

object - Object to retrieve the feature value from.

name - Name of the feature to get the value for.

Returns:

If the feature is :
• a list : value of the feature
• a single valued feature : new list containing the value as its single element
• not a feature : null

Throws:

FactoryException - Thrown if the retrieval fails.
