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 more information about this mechanism.
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 similar to those 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 can be used to determine attributes and values.
