KiokuDB::Role::Upgrade::Handlers::Table - A role for classes

SYNOPSIS

Top

    with qw(KiokuDB::Role::Upgrade::Handlers::Table);

    use constant kiokudb_upgrade_handlers_table => {

        # like the individual entries in class_version_table

        "0.01" => "0.02",
        "0.02" => sub {
            ...
        },
    };

DESCRIPTION

Top

This class lets you provide the version handling table as part of the class definition, instead of as arguments to the KiokuDB handle constructor.

See KiokuDB::TypeMap::Entry::MOP more details and KiokuDB::Role::Upgrade::Data for a lower level alternative.
