Hash::Inflator - Access hash entries through methods


version 1.100820


    my %h = (
        persons => [
                last_name  => 'Shindou',
                first_name => 'Hikaru',
                last_name  => 'Touya',
                first_name => 'Akira',
        # ...

    my $obj = Hash::Inflator->new(%h);
    print $obj->persons->[0]->first_name;


This class can inflate a hash so that you can access it using methods instead of plain hash keys. So instead of $x->{foo} you can do $x->foo().

Why would we want to do this?

First, because this way you can quickly prototype a class. Your class can inherit from Hash::Inflator and the code using your class can just assume the attributes are there. You can bother with writing the methods later. Although tools like Class::Accessor and friends make this very easy anyway.

Second, because we can.

You can call any method on the object. If the name corresponds to a hash key, its value will be returned. If there is no such key, undef will be returned. If the hash contains other hashes (however deep down), those will become inflated as well.

The code has been taken, with very little adaption, from Net::Jaiku by Rick Measham, with his permission.



Takes a hash or a hash ref and returns the inflated hash as a reference.
