Interface that defines the methods which are common between DataSource,
XADataSource and ConnectionPoolDataSource.
Public methods | |

getLogWriter()
Retrieves the log writer for this |
abstract
int
|
getLoginTimeout()
Gets the maximum time in seconds that this data source can wait while attempting to connect to a database. |
abstract
Logger
|
getParentLogger()
Return the parent Logger of all the Loggers used by this data source. |
abstract
void

setLogWriter(PrintWriter out)
Sets the log writer for this |
abstract
void
|
setLoginTimeout(int seconds)
Sets the maximum time in seconds that this data source will wait while attempting to connect to a database. |
PrintWriter getLogWriter ()
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 | |
|---|---|
PrintWriter |
the log writer for this data source or null if logging is disabled |
| Throws | |
|---|---|
SQLException |
if a database access error occurs |
See also:
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 zero.
| Returns | |
|---|---|
int |
the data source login time limit |
| Throws | |
|---|---|
SQLException |
if a database access error occurs. |
See also:
Logger getParentLogger ()
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 | |
|---|---|
Logger |
the parent Logger for this data source |
| Throws | |
|---|---|
SQLFeatureNotSupportedException |
if the data source does not use java.util.logging |
void setLogWriter (PrintWriter out)
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 |
PrintWriter:
the new log writer; to disable logging, set to null |
| Throws | |
|---|---|
SQLException |
if a database access error occurs |
See also:
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 zero.
| Parameters | |

seconds |
int:
the data source login time limit |
| Throws | |
