Pass State Class

Pass State simply passes its input to its output, performing no work. Pass States are useful when constructing and debugging state machines.

Method new()

Initialize Pass state class

Usage

Pass$new(
  state_id,
  comment = NULL,
  input_path = NULL,
  parameters = NULL,
  result_path = NULL,
  result = 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.

comment

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

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: '$')

result

(str, optional): If present, its value is treated as the output of a virtual task, and placed as prescribed by the `result_path` field, if any, to be passed on to the next state. If `result` is not provided, the output is the input.

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: '$')
