Constructor Detail

DatabaseContext

protected DatabaseContext(String name,
               String engine,
               Mapping mapping,
               TransactionManager txManager,
               ConnectionFactory factory)
                   throws MappingException

Constructs a new AbstractConnectionFactory with given name, engine and mapping. Factory will be ready to use without calling initialize first.

Parameters:

name - The Name of the database configuration.

engine - The Name of the persistence factory to use.

txManager - The transaction manager to use.

mapping - The previously loaded mapping.

Throws:

MappingException - If LockEngine could not be initialized.

DatabaseContext

protected DatabaseContext(JdoConf jdoConf,
               int index,
               Mapping mapping,
               ConnectionFactory factory)

Constructs a new AbstractConnectionFactory with given database and mapping. Initialize needs to be called before using the factory to create connections.

Parameters:

jdoConf - The JDO configuration.

index - Index of the database configuration in the JDO configuration.

mapping - The mapping to load.

Method Detail

initialize

public void initialize()
                throws MappingException

Initialize factory if it had not been initialized before.

Throws:

MappingException - If concrete factory or LockEngine fail to initialize or mapping could not be loaded.

initializeFactory

public void initializeFactory()
                       throws MappingException

Throws:

MappingException

getConnectionFactory

public ConnectionFactory getConnectionFactory()

getName

public String getName()

Get the name of the database configuration.

Returns:

The name of the database configuration.

getDatabase

public Database getDatabase()

Get the database configuration.

Returns:

The database configuration.

getMapping

public Mapping getMapping()

Get the mapping to load.

Returns:

The mapping to load.

getTransactionManager

public TransactionManager getTransactionManager()

Get the transaction manager.

Returns:

The transaction manager.

getEngine

public LockEngine getEngine()

Get the LockEngine only available after initialization.

Returns:

The LockEngine.

setClassDescriptorResolver

public void setClassDescriptorResolver(JDOClassDescriptorResolver classDescriptorResolver)

Sets a custom ClassDescriptorResolver instance.

Parameters:

classDescriptorResolver - A custom ClassDescriptorResolver instance to be used.
