Method Detail

getConnection

public JDBCConnection getConnection()
                             throws SQLException,
                                    NoAvailableConnectionException

Specified by:

getConnection in interface DataSource

Overrides:

getConnection in class JDBCDataSource<T extends JDBCConnectionPoolSettings>

Throws:

SQLException

NoAvailableConnectionException

destroy

public void destroy()
             throws SQLException

Throws:

SQLException

addIgnorableBorrowerClass

public JDBCConnectionPool addIgnorableBorrowerClass(Class inValue)

Specifies a class to be ignored when tracking connection lending. When examining the stacktrace to see who is requesting a connection, any elements from this class will be skipped and a subsequent element will be used to identify the borrower.

Parameters:

inValue - a class to be ignored when tracking connection lending

Returns:

this connection pool object to enable method chaining
