                             boolean resolve)

Description copied from interface: EObject

Returns the value of the given feature of the object; the value is optionally resolved before it is returned.

If the feature is many-valued, the result will be an EList and each object in the list will be an instance of the feature's type; the list's contents are not affected by resolve argument. Otherwise the result directly will be an instance of the feature's type; if it is a proxy, it is resolved.

Specified by:

eGet in interface EObject

Following copied from interface: org.eclipse.emf.ecore.EObject

Parameters:

feature - the feature of the value to fetch.

                 java.lang.Object newValue)

Description copied from interface: EObject

Sets the value of the given feature of the object to the new value.

If the feature is many-valued, the new value must be an EList and each object in that list must be an instance of the feature's type; the existing contents are cleared and the contents of the new value are added. Otherwise the new value directly must be an instance of the feature's type and it becomes the new value of the feature of the object. If the feature is unsettable, the modeled state becomes set; otherwise, the feature may still not considered set if the new value is the same as the default.

Specified by:

eSet in interface EObject

Following copied from interface: org.eclipse.emf.ecore.EObject

Parameters:

feature - the feature of the value to set.

Throws:

java.lang.IllegalArgumentException - if the feature is not one the meta class's features, or it isn't changeable.

ClassCastException - if there is a type conflict.

ArrayStoreException - if there is a type conflect.

eDynamicSet

public void eDynamicSet(EStructuralFeature eFeature,

eUnset

public void eUnset(EStructuralFeature eFeature)

Description copied from interface: EObject

Unsets the feature of the object.

If the feature is many-valued, the value must be an EList and that list is cleared. Otherwise, the value of the feature of the object is set to the feature's default value or the meta class's default value, as appropriate. If the feature is unsettable, the modeled state becomes unset. In any case, the feature will no longer be considered set.

Specified by:

eUnset in interface EObject

Following copied from interface: org.eclipse.emf.ecore.EObject

Parameters:

feature - the feature in question.

Throws:

java.lang.IllegalArgumentException - if the feature is not one the meta class's features, or it isn't changeable.

See Also:

EObject.eIsSet(EStructuralFeature), EObject.eSet(EStructuralFeature, Object), EObject.eGet(EStructuralFeature, boolean)

eDynamicUnset

public void eDynamicUnset(EStructuralFeature eFeature)

eIsSet

public boolean eIsSet(EStructuralFeature eFeature)

Description copied from interface: EObject

Returns whether the feature of the object is considered to be set.

If the feature is many-valued, the value must be an EList and the feature is considered set if the list is not empty. If the feature is unsettable, the modeled state is directly available and is used. Otherwise, the unresolved value of the feature of the object is compared against the feature's default value or the meta class's default value, as appropriate; the feature is considered set if it's not the same as the default.

This property can affect serialization, since defaults are typically omitted in a compact serialization.

Specified by:

eIsSet in interface EObject

Following copied from interface: org.eclipse.emf.ecore.EObject

Parameters:

feature - the feature in question.

Returns:

whether the feature of the object is set.

Throws:
