Package org.datanucleus.store
package org.datanucleus.store
Package handling the storage of classes to the datastore, and the management of the datastore.
Each type of datastore will have its own subpackage (e.g org.datanucleus.store.rdbms) and its own StoreManager.
When providing support for a new datastore you need to extend AbstractStoreManager.
The package also provides definition of StoreData - data held about each class and utilised by the StoreManager to perform its duties. This data is populated either at runtime when classes are requested, or when using an "auto-starter". There are several auto-start mechanisms. This package has ClassesAutoStarter and XMLAutoStarter.
