Method new()

Initialize SnsPublishStep task class

Usage

SnsPublishStep$new(
  state_id,
  wait_for_callback = FALSE,
  comment = NULL,
  timeout_seconds = NULL,
  timeout_seconds_path = NULL,
  heartbeat_seconds = NULL,
  heartbeat_seconds_path = NULL,
  input_path = NULL,
  parameters = NULL,
  result_path = NULL,
  output_path = NULL,
  ...
)

Arguments

state_id

(str): State name whose length **must be** less than or equal to 128 unicode characters. State names **must be** unique within the scope of the whole state machine.

wait_for_callback

(bool, optional): Boolean value set to `True` if the Task state should wait for callback to resume the operation. (default: False)

comment

(str, optional): Human-readable comment or description. (default: None)

timeout_seconds

(int, optional): Positive integer specifying timeout for the state in seconds. If the state runs longer than the specified timeout, then the interpreter fails the state with a `States.Timeout` Error Name. (default: 60)

timeout_seconds_path

(str, optional): Path specifying the state's timeout value in seconds from the state input. When resolved, the path must select a field whose value is a positive integer.

heartbeat_seconds

(int, optional): Positive integer specifying heartbeat timeout for the state in seconds. This value should be lower than the one specified for `timeout_seconds`. If more time than the specified heartbeat elapses between heartbeats from the task, then the interpreter fails the state with a `States.Timeout` Error Name.

heartbeat_seconds_path

(str, optional): Path specifying the state's heartbeat value in seconds from the state input. When resolved, the path must select a field whose value is a positive integer.

input_path

(str, optional): Path applied to the state’s raw input to select some or all of it; that selection is used by the state. (default: '$')

parameters

(list, optional): The value of this field becomes the effective input for the state.

result_path

(str, optional): Path specifying the raw input’s combination with or replacement by the state’s result. (default: '$')

output_path

(str, optional): Path applied to the state’s output after the application of `result_path`, producing the effective output which serves as the raw input for the next state. (default: '$')
