CommonsLogStopWatch()
Creates a CommonsLogStopWatch with a blank tag, no message and started at the instant of creation. |
|
CommonsLogStopWatch(Log logger)
Creates a CommonsLogStopWatch with a blank tag, no message and started at the instant of creation, using the specified Log to log stop watch messages using the info() method, or using the warn() method if an exception is passed to one of the stop or lap methods. |
|
CommonsLogStopWatch(Log logger,
int normalPriority)
Creates a CommonsLogStopWatch with a blank tag, no message and started at the instant of creation, using the specified Log to log stop watch messages at the normalPriority level specified, or using the warn() method if an exception is passed to one of the stop or lap methods. |
|
CommonsLogStopWatch(Log logger,
int normalPriority,
int exceptionPriority)
Creates a CommonsLogStopWatch with a blank tag, no message and started at the instant of creation, using the specified Log to log stop watch messages at the normalPriority level specified, or at the exceptionPriority level if an exception is passed to one of the stop or lap methods. |
|
CommonsLogStopWatch(long startTime,

|
CommonsLogStopWatch(String tag,

Creates a CommonsLogStopWatch with the tag specified, no message and started at the instant of creation, using the specified Log to log stop watch using the info() method, or using the warn() method if an exception is passed to one of the stop or lap methods. |
|
CommonsLogStopWatch(String tag,
Log logger,
int normalPriority)
Creates a CommonsLogStopWatch with the tag specified, no message and started at the instant of creation, using the specified Log to log stop watch messages at the normalPriority level specified, or using the warn() level if an exception is passed to one of the stop or lap methods. |

Method Summary | |
---|---|
CommonsLogStopWatch |
clone()
|
int |
getExceptionPriority()
Gets the level at which log statements will be made when one of the stop or lap methods that DOES take an exception is called. |
Log |
getLogger()
Gets the Apache Commons Logging Log that is used to persist logging statements when one of the stop or lap methods is called. |
int |
getNormalPriority()
Gets the level at which log statements will be made when one of the stop or lap methods that does NOT take an exception is called. |
boolean |
isLogging()
This method returns true if the Log it uses is enabled at the normalPriority level of this StopWatch. |
protected boolean |
isLogging(int atLevel)
Since Commons Logging doesn't have a first class notion of Level objects or integer values, this method converts the level value to one of the isXYZEnabled() methods on the Log. |
protected void |
log(String stopWatchAsString,
Throwable exception)
The log message is overridden to use the Apache Commons Logging Log to persist the stop watch. |
protected void |
log(String stopWatchAsString,
Throwable exception,
int atLevel)
Since Commons Logging doesn't have a first class notion of Level objects or integer values, this method maps the atLevel parameter to one of the trace(), debug(), info(), warn(), error(), or fatal() methods on the Log. |
static int |
mapLevelName(String levelName)
This utility method provides the standard mapping between log4j level names (which Perf4J uses as the standard set of possible levels) to the corresponding ..._LEVEL constant from this class. |
void |
setExceptionPriority(int exceptionPriority)
Sets the level at which log statements will be made when one of the stop or lap methods that DOES take an exception is called. |
void |
setLogger(Log logger)
Sets the Apache Commons Logging Logused to persist StopWatch instances. |
void |
setNormalPriority(int normalPriority)
Sets the level at which log statements will be made when one of the stop or lap methods that does NOT take an exception is called. |
