Method Details
-
getPooledConnection
Attempts to establish a physical database connection that can be used as a pooled connection.- Returns:
- a
PooledConnectionobject that is a physical connection to the database that thisConnectionPoolDataSourceobject represents - Throws:
SQLException- if a database access error occursSQLFeatureNotSupportedException- if the JDBC driver does not support this method- Since:
- 1.4
-
getPooledConnection
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 madepassword- the user's password- Returns:
- a
PooledConnectionobject that is a physical connection to the database that thisConnectionPoolDataSourceobject represents - Throws:
SQLException- if a database access error occursSQLFeatureNotSupportedException- if the JDBC driver does not support this method- Since:
- 1.4
-
getLogWriter
Retrieves the log writer for this
DataSourceobject.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.DriverManagerclass. When aDataSourceobject is created, the log writer is initially null; in other words, the default is for logging to be disabled.- Specified by:
getLogWriterin interfaceCommonDataSource- 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
Sets the log writer for this
DataSourceobject to the givenjava.io.PrintWriterobject.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.DriverManagerclass. When aDataSourceobject is created the log writer is initially null; in other words, the default is for logging to be disabled.- Specified by:
setLogWriterin interfaceCommonDataSource- Parameters:
out- the new log writer; to disable logging, set to null- Throws:
SQLException- if a database access error occurs- Since:
- 1.4
- See Also:
-
setLoginTimeout
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
DataSourceobject is created, the login timeout is initially zero.- Specified by:
setLoginTimeoutin interfaceCommonDataSource- Parameters:
seconds- the data source login time limit- Throws:
SQLException- if a database access error occurs.- Since:
- 1.4
- See Also:
-
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 aDataSourceobject is created, the login timeout is initially zero.- Specified by:
getLoginTimeoutin interfaceCommonDataSource- Returns:
- the data source login time limit
- Throws:
SQLException- if a database access error occurs.- Since:
- 1.4
- See Also:
-
createPooledConnectionBuilder
Creates a newPooledConnectionBuilderinstance- Implementation Requirements:
- The default implementation will throw a
SQLFeatureNotSupportedException. - Returns:
- The ConnectionBuilder instance that was created
- Throws:
SQLException- if an error occurs creating the builderSQLFeatureNotSupportedException- if the driver does not support sharding- Since:
- 9
