Interface ConnectionPoolDataSource

All Superinterfaces:

CommonDataSource

public interface ConnectionPoolDataSource
extends CommonDataSource

A factory for PooledConnection objects. An object that implements this interface will typically be registered with a naming service that is based on the Java Naming and Directory Interface (JNDI).

Since:

1.4

Method Details

getPooledConnection

PooledConnection getPooledConnection()
                              throws SQLException

Attempts to establish a physical database connection that can be used as a pooled connection.

Returns:

a PooledConnection object that is a physical connection to the database that this ConnectionPoolDataSource object represents

Throws:

SQLException - if a database access error occurs

SQLFeatureNotSupportedException - if the JDBC driver does not support this method

Since:

1.4

getPooledConnection

PooledConnection getPooledConnection(String user,
 String password)
                              throws SQLException

Attempts to establish a physical database connection that can be used as a pooled connection.

Parameters:

user - the database user on whose behalf the connection is being made

password - the user's password

Returns:

a PooledConnection object that is a physical connection to the database that this ConnectionPoolDataSource object represents

Throws:

SQLException - if a database access error occurs

SQLFeatureNotSupportedException - if the JDBC driver does not support this method

Since:

1.4

getLogWriter

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

• CommonDataSource.setLogWriter(java.io.PrintWriter)

setLogWriter

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:

SQLException - if a database access error occurs

Since:

1.4

• CommonDataSource.getLogWriter()

setLoginTimeout

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:

1.4

See Also:

• CommonDataSource.getLoginTimeout()

getLoginTimeout

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.

Since:

1.4

• CommonDataSource.setLoginTimeout(int)

createPooledConnectionBuilder

default PooledConnectionBuilder createPooledConnectionBuilder()
                                                       throws SQLException

Creates a new PooledConnectionBuilder instance

Implementation Requirements:

The default implementation will throw a SQLFeatureNotSupportedException.

Returns:

The ConnectionBuilder instance that was created

Throws:

SQLException - if an error occurs creating the builder

SQLFeatureNotSupportedException - if the driver does not support sharding

Since:
