class aws_cdk.aws_stepfunctions.PassProps(*, comment=None, input_path=None, output_path=None, parameters=None, result=None, result_path=None, state_name=None)

Bases: object

Properties for defining a Pass state.

Parameters:
  • comment (Optional[str]) – An optional description for this state. Default: No comment

  • input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: $

  • output_path (Optional[str]) – JSONPath expression to select part of the state to be the output to this state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: $

  • parameters (Optional[Mapping[str, Any]]) – Parameters pass a collection of key-value pairs, either static values or JSONPath expressions that select from the input. Default: No parameters

  • result (Optional[Result]) – If given, treat as the result of this operation. Can be used to inject or replace the current execution state. Default: No injected result

  • result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: $

  • state_name (Optional[str]) – Optional name for this state. Default: - The construct ID will be used as state name
