Class MapState

java.lang.Object

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

com.amazonaws.services.stepfunctions.builder.states.MapState

All Implemented Interfaces:

State

public final class MapState
extends TransitionState

State that allows for applying the same Iterator to multiple input elements. The Map State (identified by "Type": "Map") causes the interpreter to process all the elements of an array, potentially in parallel, with the processing of each element independent of the others.
