4.2.2 - Registries

The Registries are the place where all SchemaObjects are stored and retrieved from. It contains a registry per SchemaObject, plus a global registry which is used to retreive a SchemaObject from its OID (the OID is unique), and a list of the loaded schemas.

Basically, it's the data center of the SchemaManager. When you call SchemaManager.getAttributeType( String ), the SchemaManager will look into the AttributeTypeRegistry for the AttributeType instance associated with the name or OID.

You usually won't need to manipulate this class at all.
