public class Chain
extends software.amazon.jsii.JsiiObject
implements IChainable

(experimental) A collection of states to chain onto.

A Chain has a start and zero or more chainable ends. If there are zero ends, calling next() on the Chain will fail.

(experimental) Make a Chain with specific start and end states, and a last-added Chainable.

Parameters:

startState - This parameter is required.

endStates - This parameter is required.

lastAdded - This parameter is required.

 @NotNull
public static Chain sequence(@NotNull
                                                                      IChainable start,

(experimental) Make a Chain with the start from one chain and the ends from another.

Parameters:

start - This parameter is required.

next - This parameter is required.

start

@Stability(value=Experimental)
 @NotNull
public static Chain start(@NotNull
                                                                   IChainable state)

(experimental) Begin a new Chain from one chainable.

Parameters:

state - This parameter is required.

next

@Stability(value=Experimental)
 @NotNull
public Chain next(@NotNull
                                                           IChainable next)

(experimental) Continue normal execution with the given state.

Parameters:

next - This parameter is required.

toSingleState

@Stability(value=Experimental)
 @NotNull
public Parallel toSingleState(@NotNull
                                                                       String id,

(experimental) Return a single state that encompasses all states in the chain.

This can be used to add error handling to a sequence of states.

Be aware that this changes the result of the inner state machine to be an array with the result of the state machine in it. Adjust your paths accordingly. For example, change 'outputPath' to '$[0]'.

Parameters:

id - This parameter is required.

props -
