DBIx::DataModel::Meta - meta-information for DBIx::DataModel
The family of classes in DBIx::DataModel::Meta are designed to hold meta-information about schemas,
tables,
joins,
etc.
Under normal circumstances these classes will be mostly invisible to DBIx::DataModel users : they are used primarily for internal needs. Instances of DBIx::DataModel::Meta::Schema, DBIx::DataModel::Meta::Table, etc. are created automatically when a new schema is populated; then the relevant information is exposed through façade methods in DBIx::DataModel::Schema, DBIx::DataModel::Source::Table, etc.
This "meta-object protocol" is specific to DBIx::DataModel : it does not use Moose nor any of its alternative implementations, because the needs here are simpler and domain-specific.
Meta-objects are accessed from ordinary objects through the metadm keyword,
so as not to collide with a possible Moose integration.
This class is empty; it merely acts as parent for all DBIx::DataModel::Meta::* subclasses.
