{
			NotificationChain msgs = null;
			if ( shadowColor != null )
				msgs = ( (InternalEObject) shadowColor ).eInverseRemove( this,
						EOPPOSITE_FEATURE_BASE
								- TypePackage.LINE_SERIES__SHADOW_COLOR,
						null,
						msgs );
			if ( newShadowColor != null )
				msgs = ( (InternalEObject) newShadowColor ).eInverseAdd( this,
						EOPPOSITE_FEATURE_BASE
								- TypePackage.LINE_SERIES__SHADOW_COLOR,
						null,
						msgs );
			msgs = basicSetShadowColor( newShadowColor, msgs );
			if ( msgs != null )
				msgs.dispatch( );
		}
		else if ( eNotificationRequired( ) )
			eNotify( new ENotificationImpl( this,
					Notification.SET,
					TypePackage.LINE_SERIES__SHADOW_COLOR,
					newShadowColor,
					newShadowColor ) );
