## throw_signal
> throw_signal(signal_dto)
A signal is an event of global scope (broadcast semantics) and is delivered to all active handlers. Internally this maps to the engine's signal event received builder method `RuntimeService#createSignalEvent()`. For more information about the signal behavior, see the [Signal Events](https://docs.camunda.org/manual/7.13/reference/bpmn20/events/signal-events/) section of the [BPMN 2.0 Implementation Reference](https://docs.camunda.org/manual/7.13/reference/bpmn20/).
