GlobalDatabaseImpl

public GlobalDatabaseImpl(String dbName,
                          int lockTimeout,
                          CallbackInterceptor callback,
                          InstanceFactory instanceFactory,
                          Transaction transaction,
                          ClassLoader classLoader,
                          boolean autoStore,
                          boolean isPoolInUseForGlobalTransactions)
            throws DatabaseNotFoundException

Creates an instance of this class.
Parameters:
dbName - Database name.
lockTimeout - Lock timeout.
callback - Callback interceptors.
instanceFactory - Instance factory to use.
transaction - Current XA transaction.
classLoader - Current class loader.
autoStore - True if auto-storing is enabled.
isPoolInUseForGlobalTransactions - True if Database instanced should be cached.
Throws:
DatabaseNotFoundException - If the specified database cannot be found.

afterCompletion

public void afterCompletion(int status)

See Also:
javax.transaction.Synchronization.afterCompletion(int)

beforeCompletion

public void beforeCompletion()

begin

public void begin()
            throws PersistenceException

Specified by:
begin in interface Database
Overrides:
begin in interface AbstractDatabaseImpl

close

public void close()
            throws PersistenceException

Specified by:
close in interface Database
Overrides:
close in interface AbstractDatabaseImpl
See Also:
Database.close()

commit

public void commit()
            throws TransactionNotInProgressException,
                   TransactionAbortedException

Specified by:
commit in interface Database
Overrides:
commit in interface AbstractDatabaseImpl

finalize

protected void finalize()
            throws Throwable

Overrides Object.finalize(). Outputs a warning message to the logs if the current DatabaseImpl instance still has valid scope. In this condition - a condition that ideally should not occur at all - we close the instance as well to free up resources.
See Also:
java.lang.Object.finalize()

getJdbcConnection

public Connection getJdbcConnection()
            throws PersistenceException

Specified by:
getJdbcConnection in interface Database
Overrides:
getJdbcConnection in interface AbstractDatabaseImpl

rollback

public void rollback()
            throws TransactionNotInProgressException

Specified by:
rollback in interface Database
Overrides:
rollback in interface AbstractDatabaseImpl

setTxMap

(package private)  void setTxMap(TxDatabaseMap txMap)
