public void unsetCurve( )
	{
		boolean oldCurve = curve;
		boolean oldCurveESet = curveESet;
		curve = CURVE_EDEFAULT;
		curveESet = false;
		if ( eNotificationRequired( ) )
			eNotify( new ENotificationImpl( this,
					Notification.UNSET,
					TypePackage.LINE_SERIES__CURVE,
					oldCurve,
					CURVE_EDEFAULT,
					oldCurveESet ) );
	}
	/**

	 */
	public boolean isSetCurve( )
	{
		return curveESet;
	}
	/**
	 * <!-- begin-user-doc --> <!-- end-user-doc -->
	 * @generated

	public ColorDefinition getShadowColor( )
	{
		return shadowColor;
	}
