  - getConnection
```
public Connection getConnection()
                         throws SQLException
```
    Attempts to establish a connection with the data source that this DataSource object represents.
    
    Specified by:
    
    getConnection in interface DataSource
    
    Returns:
    
    a connection to the data source
    
    Throws:
    
    SQLException - if a database access error occurs
  - getConnection

```
    Attempts to establish a connection with the data source that this DataSource object represents.
    
    Specified by:
    
    getConnection in interface DataSource
    
    Parameters:
    
    username - the database user on whose behalf the connection is being made
    
    password - the user's password
    
    Returns:
    
    a connection to the data source
    
    Throws:
    
    SQLException - if a database access error occurs

  - getLogWriter
```
public PrintWriter getLogWriter()
                         throws SQLException
```
    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.
    
    Specified by:
    
    getLogWriter in interface CommonDataSource
    
    Returns:
    
    the log writer for this data source or null if logging is disabled
    
    Throws:
    
    SQLException - if a database access error occurs
    
    Since:
    
    1.4

  - setLogWriter
```
public void setLogWriter(PrintWriter out)
                  throws SQLException
```
    Sets the log writer for this DataSource object to the given java.io.PrintWriter 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.
    
    Specified by:
    
    setLogWriter in interface CommonDataSource
    
    Parameters:
    
    out - the new log writer; to disable logging, set to null
    
    Throws:

  - getParentLogger
```
public Logger getParentLogger()
                       throws SQLFeatureNotSupportedException
```
    Retrieves the parent logger for this data source.
    
    Specified by:
    
    getParentLogger in interface CommonDataSource
    
    Returns:
    
    The parent logger
    
    Throws:

  - setLoginTimeout
```
public void setLoginTimeout(int seconds)
                     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.
    
    Specified by:
    
    setLoginTimeout in interface CommonDataSource
    
    Parameters:
    
    seconds - the data source login time limit
    
    Throws:
    
    SQLException - if a database access error occurs.
    
    Since:

  - getLoginTimeout
```
public int getLoginTimeout()
                    throws SQLException
```
    Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. A value of zero means that the timeout is the default system timeout if there is one; otherwise, it means that there is no timeout. When a DataSource object is created, the login timeout is initially zero.
    
    Specified by:
    
    getLoginTimeout in interface CommonDataSource
    
    Returns:
    
    the data source login time limit
    
    Throws:
    
    SQLException - if a database access error occurs.

  - unwrap
```
public <T> T unwrap(Class<T> iface)
             throws SQLException
```
    Returns an object that implements the given interface to allow access to non-standard methods, or standard methods not exposed by the proxy.
    If the receiver implements the interface then the result is the receiver or a proxy for the receiver. If the receiver is a wrapper and the wrapped object implements the interface then the result is the wrapped object or a proxy for the wrapped object. Otherwise return the the result of calling 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.
    
    Specified by:
    
    unwrap in interface Wrapper
    
    Parameters:
    
    iface - A Class defining an interface that the result must implement.
    
    Returns:
    
    an object that implements the interface. May be a proxy for the actual implementing object.
    
    Throws:
    
    SQLException - If no object found that implements the interface
    
    Since:
    
    1.6
  - isWrapperFor
```
public boolean isWrapperFor(Class<?> iface)
                     throws SQLException
```
    Returns true if this either implements the interface argument or is directly or indirectly a wrapper for an object that does. Returns false otherwise. If this implements the interface then return true, else if this is a wrapper then return the result of recursively calling 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.
    
    Specified by:
    
    isWrapperFor in interface Wrapper
    
    Parameters:
    
    iface - a Class defining an interface.
    
    Returns:
    
    true if this implements the interface or directly or indirectly wraps an object that does.
    
    Throws:
    
    SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.
