State

class aws_cdk.aws_iotevents.State(*, state_name, on_enter=None, on_exit=None, on_input=None)

Bases: object

(experimental) Defines a state of a detector.

Stability:: experimental
ExampleMetadata:: infused

Example:

# Example automatically generated from non-compiling source. May contain errors.
import aws_cdk.aws_iotevents as iotevents
import aws_cdk.aws_iotevents_actions as actions

# input: iotevents.IInput

state = iotevents.State(
    state_name="MyState",
    on_enter=[iotevents.Event(
        event_name="test-event",
        condition=iotevents.Expression.current_input(input),
        actions=[actions, [
            actions.SetVariableAction("MyVariable",
                iotevents.Expression.input_attribute(input, "payload.temperature"))
        ]
        ]
    )]
)

Parameters:

state_name (str) – (experimental) The name of the state.
on_enter (Optional[Sequence[Union[Event, Dict[str, Any]]]]) – (experimental) Specifies the events on enter. The conditions of the events will be evaluated when entering this state. If the condition of the event evaluates to true, the actions of the event will be executed. Default: - no events will trigger on entering this state
on_exit (Optional[Sequence[Union[Event, Dict[str, Any]]]]) – (experimental) Specifies the events on exit. The conditions of the events are evaluated when an exiting this state. If the condition evaluates to true, the actions of the event will be executed. Default: - no events will trigger on exiting this state
on_input (Optional[Sequence[Union[Event, Dict[str, Any]]]]) – (experimental) Specifies the events on input. The conditions of the events will be evaluated when any input is received. If the condition of the event evaluates to true, the actions of the event will be executed. Default: - no events will trigger on input in this state

Stability:

experimental

Methods

transition_to(target_state, *, when, event_name=None, executing=None)

(experimental) Add a transition event to the state.

The transition event will be triggered if condition is evaluated to true.

Parameters:

target_state (State) – the state that will be transit to when the event triggered.
when (Expression) – (experimental) The condition that is used to determine to cause the state transition and the actions. When this was evaluated to true, the state transition and the actions are triggered.
event_name (Optional[str]) – (experimental) The name of the event. Default: string combining the names of the States as ${originStateName}_to_${targetStateName}
executing (Optional[Sequence[IAction]]) – (experimental) The actions to be performed with the transition. Default: - no actions will be performed

Stability:

experimental

Return type:

None

Attributes

state_name

(experimental) The name of the state.
