NAME

       Biblio::SICI::Role::ValidSegment - Role to provide common validation error handling
       functionality to the segments

VERSION

       version 0.04

DESCRIPTION

       A role that provides an attribute and some methods used for validation error handling
       functionality in the three SICI segments.

ATTRIBUTES

       validationErrors
           Stores the problem reports that are gathered when any attribute is set.  Do not access
           this directly - use the methods below.

METHODS

       "log_problem_on"( STRING, ARRAYREF )
           Stores an array ref of problem descriptions for a particular attribute.

       "clear_problem_on"( STRING )
           Removes the problem report for a particular attribute.

       HASH "list_problems"()
           Returns a hash structure with all error reports.

       BOOL "is_valid"()
           Checks if any problem reports were recorded for any attribute.  If yes, returns FALSE;
           otherwise, returns TRUE.

           Does not yet do extended verification; e.g. checking if all required data is present
           or if there are any conflicts within the stored SICI data!
