org.apache.directory.server.core.schema.SchemaPartition
A special partition designed to contain the portion of the DIT where schema information for the server is stored. In an effort to make sure that all Partition implementations are equal citizens to ApacheDS we want to be able to swap in and out any kind of Partition to store schema. This also has the added advantage of making sure the core, and hence the server is not dependent on any specific partition, which reduces coupling in the server's modules. The SchemaPartition achieves this by not really being a backing store itself for the schema entries. It instead delegates to another Partition via containment. It delegates all calls to this contained Partition. While doing so it also manages certain things:
1. Checks that schema changes are valid.
2. Updates the schema Registries on valid schema changes making sure the schema on disk is in sync with the schema in memory.
3. Will eventually manage transaction based changes to schema where between some sequence of operations the schema may be inconsistent.
4. Delegates read/write operations to contained Partition.
5. Responsible for initializing schema for the entire server. ApacheDS cannot start up other partitions until this Partition is started without having access to the Registries. This Partition supplies the Registries on initialization for the server. That's one of it's core responsibilities.
