      net.sf.sasl.aop.monitoring.execution.time.MethodExecutionTimeThresholdBean

public class MethodExecutionTimeThresholdBean
extends TimeUnitsBean

The bean could be used to configure individual execution time threshold values for the execution of a (targetObject, targetMethod, targetArguments) triple.

Method Summary

org.springframework.aop.MethodMatcher	getMethodMatcher()
int	getWaitTimeBeforeNewWarnMessageSeconds()
boolean	matches(Object targetObject, Method targetMethod, Object[] targetArguments) Returns true, if the method matcher matches the given triple.
void	setMethodMatcher(org.springframework.aop.MethodMatcher methodMatcher) Sets the method matcher will be used to decide if this threshold configuration should be used for the execution of a (targetObject, targetMethod, targetArguments) triple.
void	setWaitTimeBeforeNewWarnMessageSeconds(int waitTimeBeforeNewWarnMessageSeconds) If at time t1 a warn message was raised because a method execution was slow and at time t2 a warn message could be also raised because a method execution is again slow, than the wait time defines the minimum time that must have been gone after t1 before a new warn message could be raised.

Method Detail

getWaitTimeBeforeNewWarnMessageSeconds

public int getWaitTimeBeforeNewWarnMessageSeconds()

Returns:

positive integer value.

Since:

0.0.1 (sasl-common-aspect-library)

setWaitTimeBeforeNewWarnMessageSeconds(int)

setWaitTimeBeforeNewWarnMessageSeconds

public void setWaitTimeBeforeNewWarnMessageSeconds(int waitTimeBeforeNewWarnMessageSeconds)
                                            throws IllegalArgumentException

If at time t1 a warn message was raised because a method execution was slow and at time t2 a warn message could be also raised because a method execution is again slow, than the wait time defines the minimum time that must have been gone after t1 before a new warn message could be raised.
So if t2 <= t1 + wait time, than no warn message will be raised.
If t2 > t1 + wait time, than a warn message will be raised at t2.
The wait time should reduce warn message flooding.

Parameters:

waitTimeBeforeNewWarnMessageSeconds - positive integer value.

Throws:

IllegalArgumentException

Since:

0.0.1 (sasl-common-aspect-library)

getMethodMatcher

public org.springframework.aop.MethodMatcher getMethodMatcher()

Returns:

null or non null

Since:

0.0.1 (sasl-common-aspect-library)

setMethodMatcher(MethodMatcher)

setMethodMatcher

public void setMethodMatcher(org.springframework.aop.MethodMatcher methodMatcher)

Sets the method matcher will be used to decide if this threshold configuration should be used for the execution of a (targetObject, targetMethod, targetArguments) triple.

Parameters:

methodMatcher - null or non null

Since:

0.0.1 (sasl-common-aspect-library)

matches

public boolean matches(Object targetObject,
                       Method targetMethod,
                       Object[] targetArguments)
                throws IllegalArgumentException

Returns true, if the method matcher matches the given triple. False else. If true, than this threshold configuration should be used for the execution of the target mehod.

Parameters:

targetObject - non null

targetMethod - non null

targetArguments - non null

Returns:

Throws:

IllegalArgumentException - if targetObject or targetMethod or targetArguments is null.

Since:

0.0.1 (sasl-common-aspect-library)
