SakaiBasicDataSource
public class SakaiBasicDataSource extends BasicDataSource (Code)
	SakaiBasicDataSource extends apache common's BasicDataSource ...

Field Summary
protected boolean	m_rollbackOnReturn Configuration: to rollback each connection when returned to the pool.

Method Summary
protected synchronized DataSource	createDataSource() Sakai changes: use the SakaiPoolableConnectionFactory, removed some not-visible (damn the use of private!) code. Create (if necessary) and return the internal data source we are using to manage our connections. IMPLEMENTATION NOTE - It is tempting to use the "double checked locking" idiom in an attempt to avoid synchronizing on every single call to this method.
public void	setDefaultTransactionIsolationString(String defaultTransactionIsolation)
public void	setRollbackOnBorrow(boolean value) Set the rollback on borrow configuration.

Field Detail

m_rollbackOnReturn
protected boolean m_rollbackOnReturn(Code)
	Configuration: to rollback each connection when returned to the pool.

Method Detail

createDataSource

protected synchronized DataSource createDataSource() throws SQLException(Code)

Sakai changes: use the SakaiPoolableConnectionFactory, removed some not-visible (damn the use of private!) code.

Create (if necessary) and return the internal data source we are using to manage our connections.

IMPLEMENTATION NOTE - It is tempting to use the "double checked locking" idiom in an attempt to avoid synchronizing on every single call to this method. However, this idiom fails to work correctly in the face of some optimizations that are legal for a JVM to perform.

exception:
SQLException - if the object pool cannot be created.

setDefaultTransactionIsolationString
public void setDefaultTransactionIsolationString(String defaultTransactionIsolation)(Code)
	Set the default transaction isolation level from a string value, based on the settings and values in java.sql.Connection Parameters: defaultTransactionIsolation -

setRollbackOnBorrow
public void setRollbackOnBorrow(boolean value)(Code)
	Set the rollback on borrow configuration. Parameters: value - if true, rollback each connection when borrowed from the pool, if false, do not.
