def extract_list_operator(value, processor, argument, variables, mapping)

Returns:
  • (String) - The extracted result.

Parameters:
  • mapping (Hash) -- The mapping of variables to values.

  • argument (String) -- The argument to the operator.
  • processor (#restore) -- The processor object.
  • value (String) -- The unparsed value to extract from.
