getLogWriter

public 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.

Specified by:

getLogWriter in interface CommonDataSource

Specified by:

getLogWriter in interface ConnectionPoolDataSource

Specified by:

getLogWriter in interface DataSource

Specified by:

getLogWriter in interface XADataSource

Returns:

the log writer for this data source or null if logging is disabled

See Also:

setLogWriter(java.io.PrintWriter)

setLogWriter

public 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.

Specified by:

setLogWriter in interface CommonDataSource

Specified by:

setLogWriter in interface ConnectionPoolDataSource

Specified by:

setLogWriter in interface DataSource

Specified by:

setLogWriter in interface XADataSource

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 zero.

Specified by:

getLoginTimeout in interface CommonDataSource

Specified by:

getLoginTimeout in interface ConnectionPoolDataSource

Specified by:

getLoginTimeout in interface DataSource

Specified by:

getLoginTimeout in interface XADataSource

Returns:

the data source login time limit

See Also:

setLoginTimeout(int)

setLoginTimeout

public 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.

Specified by:

setLoginTimeout in interface CommonDataSource

Specified by:

setLoginTimeout in interface ConnectionPoolDataSource

Specified by:

setLoginTimeout in interface DataSource

Specified by:

setLoginTimeout in interface XADataSource

Parameters:

seconds - the data source login time limit

unwrap

public <T> T unwrap(Class<T> iface)
             throws 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 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 Wrapper

Parameters:

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

Returns:

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

Throws:

SQLException - If no object found that implements the interface

Since:

1.6

isWrapperFor

public boolean isWrapperFor(Class<?> interfaceOrWrapper)
                     throws SQLException

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 Wrapper

Parameters:

interfaceOrWrapper - a Class defining an interface.

Returns:

true if this implements the interface or directly or indirectly wraps an object that does.

Throws:

SQLException - if an error occurs while determining whether this is a wrapper for an object with the given interface.
