Examples of org.datanucleus.store.appengine.DatastoreTable

org.datanucleus.store.appengine.DatastoreTable
Describes a 'table' in the datastore. We don't actually have tables, but we need to represent this logically in order to take care of all the nice mapping logic that datanucleus does for us. This code is largely copied from AbstractClassTable, ClassTable, TableImpl, and AbstractTable TODO(maxr): Refactor the RDBMS classes into the mapped package so we can refactor this. @author Max Ross
