Class ParallelState

java.lang.Object

com.amazonaws.services.stepfunctions.builder.states.TransitionState

com.amazonaws.services.stepfunctions.builder.states.ParallelState

All Implemented Interfaces:

State

public final class ParallelState
extends TransitionState

State that allows for parallel execution of Branchs. A Parallel state causes the interpreter to execute each branch starting with the state named in its “StartAt” field, as concurrently as possible, and wait until each branch terminates (reaches a terminal state) before processing the Parallel state's “Next” field.
