DESCRIPTION

28       You must read Exception::Class before reading on.
29
30       This module creates all the exception class used by Config::Model.
31
32       All expection class name begins with "Config::Model::Exception::"
33
34       The exception classes are:
35
36       "Any"
37           Base class. It accepts an "object" argument. The user must pass the
38           reference of the object where the exception occured. The object
39           name (or xpath) will be used to generate the error message.
40
41         TODO: list all exception classes and hierarchy.

How to get trace

44       By default, most of the exceptions will not print out the stack trace.
45       For debug purpose, you can force a strack trace.
46
47       For instance, if you want a stack trace for an "unknown element" error,
48       you must add this line in your script:
49
50         Config::Model::Exception::UnknownElement->Trace(1) ;
51
52       If you're not sure which class to trace, add this line in your script:
53
54         Config::Model::Exception::Any->Trace(1) ;
