NAME
Data::Semantic - Common API for data with semantics attached to them
VERSION
version 1.101620
DESCRIPTION
There are various distributions on CPAN dealing with data that has
semantics attached them. For example, an IP address is not just a
string, but it has a format the can be checked.
There is Data::Domain. It does not store the values to be tested, it
just tests them and records messages.
Then there is Class::Value. It does store the value and it records
exceptions.
Both share the same underlying concept of a value that can be tested for
validity. Data::Semantic provides this underlying mechanism. It does not
store the value and it does not record the message. All it does is
validate data and say whether it is good or bad. What Data::Domain or
Class::Value do with this information is their thing.
If you have a new type of semantic data, here is how you can handle it.
if it can be a Regexp::Common pattern:
make a Regexp::Common pattern
make a subclass of Data::Semantic::RegexpAdapter
else:
make a subclass of Data::Semantic::Base
if there is a CPAN module for that data type:
wrap that module in your semantic data class
forward methods onto the object if possible
make an adapter class for Class::Value
make an adapter class for Data::Domain
METHODS
new
my $obj = Data::Semantic->new;
my $obj = Data::Semantic->new(%args);
Creates and returns a new object. The constructor will accept as
arguments a list of pairs, from component name to initial value. For
each pair, the named component is initialized by calling the method of
the same name with the given value. If called with a single hash
reference, it is dereferenced and its key/value pairs are set as
described before.
