Method Detail
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.
- Returns:
- the log writer for this data source or null if logging is disabled
- Throws:
-
SQLException
- if a database access error occurs - See Also:
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.
- Parameters:
-
out
- the new log writer; to disable logging, set to null - Throws:
-
SQLException
- if a database access error occurs - See Also:
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.
- Parameters:
-
seconds
- the data source login time limit - Throws:
-
SQLException
- if a database access error occurs. - See Also:
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.
- Returns:
- the data source login time limit
- Throws:
-
SQLException
- if a database access error occurs. - See Also:
setLoginTimeout(int)
getParentLogger
Logger getParentLogger() throws SQLFeatureNotSupportedException
Return the parent Logger of all the Loggers used by this data source. This should be the Logger farthest from the root Logger that is still an ancestor of all of the Loggers used by this data source. Configuring this Logger will affect all of the log messages generated by the data source. In the worst case, this may be the root Logger.
- Returns:
- the parent Logger for this data source
- Throws:
-
SQLFeatureNotSupportedException
- if the data source does not usejava.util.logging
- Since:
- 1.7
createShardingKeyBuilder
default ShardingKeyBuilder createShardingKeyBuilder() throws SQLException
Creates a new ShardingKeyBuilder
instance
- Implementation Requirements:
- The default implementation will throw a
SQLFeatureNotSupportedException
. - Returns:
- The ShardingKeyBuilder instance that was created
- Throws:
-
SQLException
- if an error occurs creating the builder -
SQLFeatureNotSupportedException
- if the driver does not support this method - Since:
- 9
