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.
