Class LogLog
This class used to output log statements from within the log4j package.
Log4j components cannot make log4j logging calls. However, it is
sometimes useful for the user to learn about what log4j is
doing. You can enable log4j internal logging by defining the
log4j.configDebug variable.
All log4j internal debug calls go to
System.out
where as internal error messages are sent to
System.err
. All internal messages are prepended with
the string "log4j: ".
static void | debug(String msg) - This method is used to output log4j internal debug
statements.
|
static void | debug(String msg, Throwable t) - This method is used to output log4j internal debug
statements.
|
static void | error(String msg) - This method is used to output log4j internal error
statements.
|
static void | error(String msg, Throwable t) - This method is used to output log4j internal error
statements.
|
static void | setInternalDebugging(boolean enabled) - Allows to enable/disable log4j internal logging.
|
static void | setQuietMode(boolean quietMode) - In quite mode no LogLog generates strictly no output, not even
for errors.
|
static void | warn(String msg) - This method is used to output log4j internal warning
statements.
|
static void | warn(String msg, Throwable t) - This method is used to output log4j internal warnings.

CONFIG_DEBUG_KEY
public static final String CONFIG_DEBUG_KEY
Use DEBUG_KEY
instead.
Defining this value makes log4j components print log4j-internal
debug statements to
System.out
.
The value of this string is
log4j.configDebug.
Note that the search for all option names is case sensitive.
DEBUG_KEY
public static final String DEBUG_KEY
Defining this value makes log4j print log4j-internal debug
statements to
System.out
.
The value of this string is
log4j.debug.
Note that the search for all option names is case sensitive.
debugEnabled
protected static boolean debugEnabled
debug
public static void debug(String msg)
This method is used to output log4j internal debug
statements. Output goes to System.out
.
debug
public static void debug(String msg,
Throwable t)
This method is used to output log4j internal debug
statements. Output goes to System.out
.
error
public static void error(String msg)
This method is used to output log4j internal error
statements. There is no way to disable error statements.
Output goes to System.err
.
error
public static void error(String msg,
Throwable t)
This method is used to output log4j internal error
statements. There is no way to disable error statements.
Output goes to System.err
.
setInternalDebugging
public static void setInternalDebugging(boolean enabled)
Allows to enable/disable log4j internal logging.
setQuietMode
public static void setQuietMode(boolean quietMode)
In quite mode no LogLog generates strictly no output, not even
for errors.
quietMode
- A true for not
warn
public static void warn(String msg)
This method is used to output log4j internal warning
statements. There is no way to disable warning statements.
Output goes to System.err
.
warn
public static void warn(String msg,
Throwable t)
This method is used to output log4j internal warnings. There is
no way to disable warning statements. Output goes to
System.err
.
