Constructor Detail

SingleStoreDataSource

public SingleStoreDataSource(String url)
                      throws SQLException

Throws:

SQLException

Method Detail

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

SQLTimeoutException - when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

getConnection

public Connection getConnection(String username,
                                String password)
                         throws SQLException

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

SQLTimeoutException - when the driver has determined that the timeout value specified by the setLoginTimeout method has been exceeded and has at least tried to cancel the current database connection attempt

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

isWrapperFor

public boolean isWrapperFor(Class<?> iface)

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.

getLogWriter

public PrintWriter getLogWriter()

Implementation doesn't use logwriter

Specified by:

getLogWriter in interface CommonDataSource

Returns:

the log writer for this data source or null if logging is disabled

See Also:

setLogWriter(java.io.PrintWriter)

setLogWriter

public void setLogWriter(PrintWriter out)

Implementation doesn't use logwriter

Specified by:

setLogWriter in interface CommonDataSource

Parameters:

out - the new log writer; to disable logging, set to null

See Also:

getLogWriter()

getLoginTimeout

public int getLoginTimeout()

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 to 30s.

Specified by:

getLoginTimeout in interface CommonDataSource

Returns:

the data source login time limit

See Also:

setLoginTimeout(int)

setLoginTimeout

public void setLoginTimeout(int seconds)

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 30s.

Specified by:

setLoginTimeout in interface CommonDataSource

Parameters:

seconds - the data source login time limit

Since:

1.4

getLoginTimeout()

getParentLogger

public Logger getParentLogger()

Not implemented

Specified by:

getParentLogger in interface CommonDataSource

Returns:

the parent Logger for this data source

public PooledConnection getPooledConnection()
                                     throws SQLException

Specified by:
