LocalDatabaseImpl

public LocalDatabaseImpl(String dbName,
                         int lockTimeout,
                         CallbackInterceptor callback,
                         InstanceFactory instanceFactory,
                         ClassLoader classLoader,
                         boolean autoStore)
            throws DatabaseNotFoundException

Creates an instance of this class.
Parameters:
dbName - database name
lockTimeout - Lock timeout
callback - Callback interceptor
instanceFactory - Instance factory.
classLoader - Current class loader
autoStore - Indicates whetehr to use 'auto-storing'
Throws:
DatabaseNotFoundException - If the specified database configuration cannot be found.

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.

java.lang.Object.finalize()

getJdbcConnection

public Connection getJdbcConnection()
            throws PersistenceException

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

rollback

public void rollback()
            throws TransactionNotInProgressException

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