AWS Step Functions integrates with services directly in the Amazon States Language.

You can control these AWS services using service integration patterns:

Example:

 // Define a state machine with one Pass state
 StateMachine child = StateMachine.Builder.create(this, "ChildStateMachine")
         .definition(Chain.start(new Pass(this, "PassState")))
         .build();
 // Include the state machine in a Task state with callback pattern
 StepFunctionsStartExecution task = StepFunctionsStartExecution.Builder.create(this, "ChildTask")
         .stateMachine(child)
         .integrationPattern(IntegrationPattern.WAIT_FOR_TASK_TOKEN)
         .input(TaskInput.fromObject(Map.of(
                 "token", JsonPath.getTaskToken(),
                 "foo", "bar")))
         .name("MyExecutionName")
         .build();
 // Define a second state machine with the Task state above
 // Define a second state machine with the Task state above
 StateMachine.Builder.create(this, "ParentStateMachine")
         .definition(task)
         .build();

Method Details

values

public static IntegrationPattern[] values()

Returns an array containing the constants of this enum type, in the order they are declared.

Returns:

an array containing the constants of this enum type, in the order they are declared

valueOf

public static IntegrationPattern valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name

NullPointerException - if the argument is null
