ConstReadonlyError: "error"The calculation engine failed to start and is unable to perform calculations. Unusable as ICalculation.Status.Off is, but ICalculation.ready does not start it again; ICalculation.start does. This status represents engine-level errors, separate from cell-level errors (which are represented as Scalar.Error values).
ReadonlyOff: "off"The calculation engine is disabled.
ReadonlyRunning: "running"The calculation engine is running: it follows the model and answers for it. Whether it has
work in hand is its calculation state (getCalculationState()), not this.
ReadonlyStarting: "starting"The calculation engine is starting up and initializing its internal state.
ReadonlyStopping: "stopping"The calculation engine is stopping and cleaning up its internal state.
Represents the calculation engine's overall status.
