public class Map
extends State
implements INextable
A Map state can be used to run a set of steps for each element of an input array.
A Map state will execute the same steps for multiple entries of an array in the state input.
While the Parallel state executes multiple branches of steps using the same input, a Map state will execute the same steps for multiple entries of an array in the state input.
Example:
Map map = Map.Builder.create(this, "Map State")
.maxConcurrency(1)
.itemsPath(JsonPath.stringAt("$.inputForMap"))
.build();
map.iterator(new Pass(this, "Pass State"));
