Retrieves the log writer for this DataSource object.
The log writer is a character output stream to which all logging and tracing messages for this data source
will be printed. This includes messages printed by the methods of this object, messages printed by methods of
other objects manufactured by this object, and so on. Messages printed to a data source specific log writer are
not printed to the log writer associated with the java.sql.DriverManager class. When a
DataSource object is created, the log writer is initially null; in other words, the default is for
logging to be disabled.

throws SQLException
Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. A
value of zero specifies that the timeout is the default system timeout if there is one; otherwise, it specifies
that there is no timeout. When a DataSource object is created, the login timeout is initially zero.

unwrap recursively on the
wrapped object or a proxy for that result. If the receiver is not a wrapper and does not implement the interface,
then an SQLException is thrown.unwrap in interface Wrapperiface - A Class defining an interface that the result must implement.SQLException - If no object found that implements the interfacepublic boolean isWrapperFor(Class<?> iface) throws SQLException
isWrapperFor on the wrapped object. If this
does not implement the interface and is not a wrapper, return false. This method should be implemented as a
low-cost operation compared to unwrap so that callers can use this method to avoid expensive
unwrap calls that may fail. If this method returns true then calling unwrap with the
same argument should succeed.isWrapperFor in interface Wrapperiface - a Class defining an interface.SQLException - if an error occurs while determining whether this is a wrapper for an object with
