Implements IConstruct, IDependable, IChainable, INextable

Define a Wait state in the state machine.

A Wait state can be used to delay execution of the state machine for a while.

Example

const convertToSeconds = new tasks.EvaluateExpression(this, 'Convert to seconds', {
  expression: '$.waitMilliseconds / 1000',
  resultPath: '$.waitSeconds',
});

const createMessage = new tasks.EvaluateExpression(this, 'Create message', {
  // Note: this is a string inside a string.
  expression: '`Now waiting ${$.waitSeconds} seconds...`',
  runtime: lambda.Runtime.NODEJS_LATEST,
  resultPath: '$.message',
});

const publishMessage = new tasks.SnsPublish(this, 'Publish message', {
  topic: new sns.Topic(this, 'cool-topic'),
  message: sfn.TaskInput.fromJsonPathAt('$.message'),
  resultPath: '$.sns',
});

const wait = new sfn.Wait(this, 'Wait', {
  time: sfn.WaitTime.secondsPath('$.waitSeconds'),
});

new sfn.StateMachine(this, 'StateMachine', {
  definition: convertToSeconds
    .next(createMessage)
    .next(publishMessage)
    .next(wait),
});

Methods

Name	Description
addPrefix(x)	Add a prefix to the stateId of this state.
bindToGraph(graph)	Register this state as part of the given graph.
next(next)	Continue normal execution with the given state.
toStateJson()	Return the Amazon States Language object for this state.
toString()	Returns a string representation of this construct.

---

addPrefix(x)

public addPrefix(x: string): void

Parameters

• x string

Add a prefix to the stateId of this state.

---

bindToGraph(graph)

public bindToGraph(graph: StateGraph): void

Parameters

• graph StateGraph

next(next)

public next(next: IChainable): Chain

Parameters

• next IChainable

Returns

• Chain

Continue normal execution with the given state.

---

toStateJson()

public toStateJson(): json

Returns

• json

Return the Amazon States Language object for this state.

---

toString()

public toString(): string

Returns

• string

Returns a string representation of this construct.
