Convert the data held in this object to a structure (eg,
struct) that represents all the data elements.
This method is used to recursively convert the object into a
self-documenting form that can easily be used for various
purposes, including diffs and queries.
These structures may be primitive Python types (string,
integer, boolean, etc.) or complex Python types (lists,
tuples, or dicts). If the return type is a dict, then the keys
of the dict match the fieldname of the object. If the return
struct (or value of a dict key) is a list, then it is a list
of structs. Otherwise, the struct is just the value of the
attribute.
