Method Detail

getContext

StoreContext getContext()

Current persistence context.

getConfiguration

JDBCConfiguration getConfiguration()

Return the configuration for this runtime.

getDBDictionary

DBDictionary getDBDictionary()

Return the dictionary in use.

getSQLFactory

SQLFactory getSQLFactory()

Return the SQL factory for this runtime.

getLockManager

JDBCLockManager getLockManager()

If the lock manager in use is a JDBCLockManager, return it.

getConnection

Connection getConnection()

Return a SQL connection to the database. The close method should always be called on the connection to free any resources it is using. When appropriate, the close method is implemented as a no-op.

getNewConnection

Connection getNewConnection()

Return a new SQL connection to the database. This is used when the current connection still has a open result set and a new database operation needs to be done. The close method should always be called on the connection to free any resources it is using. When appropriate, the close method is implemented as a no-op.

getFetchConfiguration

JDBCFetchConfiguration getFetchConfiguration()

Return the current default fetch configuration.

newDataStoreId

Id newDataStoreId(long id,
                  ClassMapping mapping,
                  boolean subs)

Create a new datastore identity object from the given id value and mapping.

find

Object find(Object oid,
            ValueMapping vm,
            JDBCFetchConfiguration fetch)

Find the object with the given oid. Convenience method on top of the store's persistence context.

Parameters:

vm - the mapping holding this oid, or null if not applicable

loadSubclasses

void loadSubclasses(ClassMapping mapping)

Makes sure all subclasses of the given type are loaded in the JVM. This is usually done automatically.
