public Oracle9PersistenceManager()

Method Detail

init

public void init(PMContext context)
          throws Exception

Initializes the persistence manager. The persistence manager is permanently bound to the given context, and any required external resources are acquired.

An appropriate exception is thrown if the persistence manager initialization fails for whatever reason. In this case the state of the persistence manager is undefined and the instance should be discarded. Initializes the internal structures of this abstract persistence manager.

Retrieve the oracle.sql.BLOB class via reflection, and initialize the values for the DURATION_SESSION and MODE_READWRITE constants defined there.

Specified by:

init in interface PersistenceManager

Overrides:

init in class OraclePersistenceManager

Parameters:

context - persistence manager context

Throws:

Exception - if the persistence manager initialization failed

See Also:

oracle.sql.BLOB#DURATION_SESSION, oracle.sql.BLOB#MODE_READWRITE

createDBBlobStore

protected BundleDbPersistenceManager.CloseableBLOBStore createDBBlobStore(PMContext context)
                                                                   throws Exception

Description copied from class: BundleDbPersistenceManager

Creates a blob store that uses the database. This is called by init if BundleDbPersistenceManager.useDbBlobStore() returns true.

Overrides:

createDBBlobStore in class BundleDbPersistenceManager

Parameters:

context - the persistence manager context

Returns:

a blob store

Throws:

Exception - if an error occurs.

storeBundle

protected void storeBundle(NodePropBundle bundle)
                    throws ItemStateException

Description copied from class: BundleDbPersistenceManager

Stores a bundle to the underlying system.

Overrides:

storeBundle in class BundleDbPersistenceManager

Parameters:

bundle - the bundle to store

Throws:

ItemStateException - if an error while storing occurs.

store

public void store(NodeReferences refs)
           throws ItemStateException

Description copied from class: BundleDbPersistenceManager

Stores a node references to the underlying system. This method uses shared PreparedStatements, which must be used strictly sequentially. Because this method synchronizes on the persistence manager instance, there is no need to synchronize on the shared statement. If the method would not be synchronized, the shared statement must be synchronized.

Overrides:

store in class BundleDbPersistenceManager

Parameters:

refs - the node references to store.

Throws:

ItemStateException - if an error while storing occurs.

createTemporaryBlob

protected Blob createTemporaryBlob(InputStream in)
                            throws Exception

Creates a temporary oracle.sql.BLOB instance via reflection and spools the contents of the specified stream.

Throws:

Exception

freeTemporaryBlob

protected void freeTemporaryBlob(Object blob)
                          throws Exception

Frees a temporary oracle.sql.BLOB instance via reflection.

Throws:

Exception
