A data domain is a description of a set of values, either scalar or structured
|
|
(arrays or hashes). The description can include many constraints, like minimal
|
|
or maximal values, regular expressions, required fields, forbidden fields, and
|
|
also contextual dependencies. From that description, one can then invoke the
|
|
domain's inspect method to check if a given value belongs to it or not. In case
|
|
of mismatch, a structured set of error messages is returned.
|
|
|
|
The motivation for writing this package was to be able to express in a compact
|
|
way some possibly complex constraints about structured data. Typically the data
|
|
is a Perl tree (nested hashrefs or arrayrefs) that may come from XML, JSON, from
|
|
a database through DBIx::DataModel, or from postprocessing an HTML form through
|
|
CGI::Expand. Data::Domain is a kind of tree parser on that structure, with some
|
|
facilities for dealing with dependencies within the structure, and with several
|
|
options to finely tune the error messages returned to the user.
