The AttrParse mechanism processes the results returned by the getUser and getAllUsers actions through the standard output stream. See Chapter 49, Implementing the AttrParse Object for details about implementing AttrParse objects.
For getUser actions, AttrParse returns a map of user attributes. For the getAllUsers action, it generates a map of maps. Each entry for the returned map contains the following.
A value that is a map of user attributes like typically returned by AttrParse.
A key that is the account ID, or if that is not known, the name.
The collectCsvHeader and collectCsvLines AttrParse tokens must be used to determine attributes and values. Do not use other AttrParse tokens that perform similar operations.
