Constructor Detail

MariaDbPoolDataSource

public MariaDbPoolDataSource()

Constructor

MariaDbPoolDataSource

public MariaDbPoolDataSource(java.lang.String url)
                      throws java.sql.SQLException

Constructor with url

Parameters:

url - connection string

Throws:

java.sql.SQLException - if configuration fails

Method Detail

config

private void config()
             throws java.sql.SQLException

Throws:

java.sql.SQLException

getConnection

public java.sql.Connection getConnection()
                                  throws java.sql.SQLException

Attempts to establish a connection with the data source that this DataSource object represents.

Specified by:

getConnection in interface javax.sql.DataSource

Returns:

a connection to the data source

Throws:

java.sql.SQLException - if a database access error occurs

java.sql.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 java.sql.Connection getConnection(java.lang.String username,
                                         java.lang.String password)
                                  throws java.sql.SQLException

Attempts to establish a connection with the data source that this DataSource object represents.

Specified by:

getConnection in interface javax.sql.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:

java.sql.SQLException - if a database access error occurs

java.sql.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(java.lang.Class<T> iface)
             throws java.sql.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 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 java.sql.Wrapper

Parameters:

iface - A Class defining an interface that the result must implement.

Returns:

an object that implements the interface. Maybe a proxy for the actual implementing object.

Throws:

java.sql.SQLException - If no object found that implements the interface

isWrapperFor

public boolean isWrapperFor(java.lang.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 java.sql.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 java.io.PrintWriter getLogWriter()

Implementation doesn't use logwriter

Specified by:

getLogWriter in interface javax.sql.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(java.io.PrintWriter out)

Implementation doesn't use logwriter

Specified by:

setLogWriter in interface javax.sql.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 javax.sql.CommonDataSource

Returns:

the data source login time limit

See Also:

setLoginTimeout(int)

setLoginTimeout

public void setLoginTimeout(int seconds)
                     throws java.sql.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 30s.

Specified by:

setLoginTimeout in interface javax.sql.CommonDataSource

Parameters:

seconds - the data source login time limit

Throws:

java.sql.SQLException - if wrong configuration set

See Also:

getLoginTimeout()
