55 This class is designed to support the Class::DBI connection-as-classdata style
56 for DBIx::Class. You are *strongly* recommended to use a DBIx::Class::Schema
57 instead; DBIx::Class::DB will not undergo new development and will be moved
58 to being a CDBICompat-only component before 1.0.
64 Sets or gets the storage backend. Defaults to L<DBIx::Class::Storage::DBI>.
70 Sets or gets the class to use for resolving a class. Defaults to
71 L<DBIx::Class::ClassResolver::Passthrough>, which returns whatever you give
72 it. See resolve_class below.

96 Creates a class method ->schema_instance which contains a DBIx::Class::Schema;
97 all class-method operations are proxies through to this object. If you don't
98 call ->connection in your DBIx::Class::DB subclass at load time you *must*
99 call ->setup_schema_instance in order for subclasses to find the schema and
100 register themselves with it.
