Method Detail
-
getLogger
static Logger getLogger(Class<?> clazz)
Construct a new Logger instance.- Parameters:
clazz- the logger category class- Returns:
Loggerinstance
-
getLogger
static Logger getLogger(String name)
Construct a new Logger instance.- Parameters:
name- the logger category name- Returns:
Loggerinstance
-
isTraceEnabled
boolean isTraceEnabled()
Is the logger instance enabled for the TRACE level?- Returns:
- True if this Logger is enabled for the TRACE level, false otherwise.
-
trace
void trace(String msg)
Log a message at the TRACE level.- Parameters:
msg- the message string to be logged
-
trace
void trace(String format, Object... arguments)
Log a message at the TRACE level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the TRACE level. However, this variant incurs the hidden (and relatively small) cost of creating an
Object[]before invoking the method, even if this logger is disabled for TRACE.- Parameters:
format- the format stringarguments- a list of 3 or more arguments
-
trace
void trace(String msg, Throwable t)
Log an exception (throwable) at the TRACE level with an accompanying message.- Parameters:
msg- the message accompanying the exceptiont- the exception (throwable) to log
-
isDebugEnabled
boolean isDebugEnabled()
Is the logger instance enabled for the DEBUG level?- Returns:
- True if this Logger is enabled for the DEBUG level, false otherwise.
-
debug
void debug(String msg)
Log a message at the DEBUG level.- Parameters:
msg- the message string to be logged
-
debug
void debug(String format, Object... arguments)
Log a message at the DEBUG level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the DEBUG level. However, this variant incurs the hidden (and relatively small) cost of creating an
Object[]before invoking the method, even if this logger is disabled for DEBUG.- Parameters:
format- the format stringarguments- a list of 3 or more arguments
-
debug
void debug(String msg, Throwable t)
Log an exception (throwable) at the DEBUG level with an accompanying message.- Parameters:
msg- the message accompanying the exceptiont- the exception (throwable) to log
-
isInfoEnabled
boolean isInfoEnabled()
Is the logger instance enabled for the INFO level?- Returns:
- True if this Logger is enabled for the INFO level, false otherwise.
-
info
void info(String msg)
Log a message at the INFO level.- Parameters:
msg- the message string to be logged
-
info
void info(String format, Object... arguments)
Log a message at the INFO level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the INFO level. However, this variant incurs the hidden (and relatively small) cost of creating an
Object[]before invoking the method, even if this logger is disabled for INFO.- Parameters:
format- the format stringarguments- a list of 3 or more arguments
-
info
void info(String msg, Throwable t)
Log an exception (throwable) at the INFO level with an accompanying message.- Parameters:
msg- the message accompanying the exceptiont- the exception (throwable) to log
-
warn
void warn(String msg)
Log a message at the WARN level.- Parameters:
msg- the message string to be logged
-
warn
void warn(String format, Object... arguments)
Log a message at the WARN level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the WARN level. However, this variant incurs the hidden (and relatively small) cost of creating an
Object[]before invoking the method, even if this logger is disabled for WARN.- Parameters:
format- the format stringarguments- a list of 3 or more arguments
-
warn
void warn(String msg, Throwable t)
Log an exception (throwable) at the WARN level with an accompanying message.- Parameters:
msg- the message accompanying the exceptiont- the exception (throwable) to log
-
error
void error(String msg)
Log a message at the ERROR level.- Parameters:
msg- the message string to be logged
-
error
void error(String format, Object... arguments)
Log a message at the ERROR level according to the specified format and arguments.
This form avoids superfluous string concatenation when the logger is disabled for the ERROR level. However, this variant incurs the hidden (and relatively small) cost of creating an
Object[]before invoking the method, even if this logger is disabled for ERROR.- Parameters:
format- the format stringarguments- a list of 3 or more arguments
