public class PersistenceManagerImpl

extends Object

implements KodoPersistenceManagerSPI

Concrete PersistenceManager for use with this common runtime. The PersistenceManager handles JDO-specific behavior, but leaves all interaction with the data store to a StoreManager that must be supplied at initialization.

All options defined in the JDO 1.0 specification are supported, with the exception of non durable identity and changing primary keys.

Field Summary

protected static int	FLUSH_COMMIT Flush in preparation of commit.
protected static int	FLUSH_INC Incremental flush.
protected static int	FLUSH_LOGICAL Run persistence-by-reachability and other flush-time operations without accessing the database.
protected static int	FLUSH_ROLLBACK Flush to check consistency of cache, then immediately rollback changes.

Method Detail

initialize

public void initialize(PersistenceManagerFactoryImpl factory,
                       StoreManager sm,
                       String user,
                       String pass,
                       boolean managed,
                       int connMode)

Initialize the persistence manager. This method is called automatically by the factory before use.

Parameters:

factory - the PersistenceManagerFactory used to create this PersistenceManager

sm - a concrete StoreManager implementation to handle interaction with the data store

user - the username this PersistenceManager represents; used when pooling managers to make sure that a request to the PersistenceManagerFactory for a connection with an explicit user is delegated to a suitable PersistenceManager

pass - the password for the above user

managed - the transaction mode

connMode - the connection retain mode

finalize

protected void finalize()
                 throws Throwable

Close on finalize.

Overrides:

finalize in class Object

newManagedObjectCache

protected Map newManagedObjectCache()

Create a Map to be used for the managed object cache. Maps oids to state managers. By default, this creates a ReferenceMap with soft values.

getCloseOnManagedCommit

public boolean getCloseOnManagedCommit()

Whether to really close in a managed environment if the close method has been called and the transaction subsequently ends. Defaults to true.

setCloseOnManagedCommit

public void setCloseOnManagedCommit(boolean close)

Whether to really close in a managed environment if the close method has been called and the transaction subsequently ends. Defaults to true.

getEvictFromDataCache

public boolean getEvictFromDataCache()

Whether to also evict an object from the data cache when it is evicted through the persistence manager.

setEvictFromDataCache

public void setEvictFromDataCache(boolean evict)

Whether to also evict an object from the data cache when it is evicted through the persistence manager.

setPopulateDataCache

public void setPopulateDataCache(boolean cacheObjects)

Description copied from interface: KodoPersistenceManager

Whether to populate the DataCache with objects used by this transaction. Defaults to true.

Specified by:

setPopulateDataCache in interface KodoPersistenceManager

isPopulateDataCache

public boolean isPopulateDataCache()

Description copied from interface: KodoPersistenceManager

Whether objects accessed during this transaction will be added to the DataCache. Defaults to true.

Specified by:

setLargeTransaction

public void setLargeTransaction(boolean largeTransaction)

Description copied from interface: KodoPersistenceManager

If a large number of objects will be created, modified, or deleted during this transaction setting this option to true will reduce memory usage if you perform periodic flushes. Upon transaction commit the data cache will have to more aggressively flush objects. The data cache will have to flush instances of objects for each class of object modified during the transaction. A side benefit of large transaction mode is that smaller update messages can be used for RemoteCommitEvents. Defaults to false.

Specified by:

setLargeTransaction in interface KodoPersistenceManager
