Description

Interface Summary

DatastoreAdapter	Definition of a datastore adapter.
DatastoreClass	Representation of a Java class in a datastore.
DatastoreContainerObject	This represents a container of fields.
DatastoreElementContainer	Class representing a container of elements (collection/array) mapped in a datastore (join table).
DatastoreField	Representation of a Java field (component) in a datastore.
DatastoreIdentifier	Representation of an datastore identifier in an ORM datastore.

Package org.datanucleus.store.mapped Description

This package provides classes for the management of datastores that are "mapped". That is, any datastore that needs information for classes/fields to be mapped into tables/columns. This type of datastore would be something like RDBMS, which uses all of the concepts provided, or also Google BigTable that supports some ORM concepts.
