Annotation Type NegativeExponential

@Retention(value=RUNTIME)
@Target(value={TYPE,METHOD})
public @interface NegativeExponential

NegativeExponential represents a negative exponential distribution for think or cycle time distribution.

Required Element Summary

double

cycleDeviation The allowed deviation from the targeted time, in %.

Optional Element Summary

int	cycleMax The max cycle or think time in milliseconds, defaults to 5xcycleMean.
int	cycleMean The mean cycle or think time in milliseconds.
int	cycleMin The min cycle or think time in milliseconds.
CycleType	cycleType The type of cycle to be used.
boolean	truncateAtMin Whether to truncate the distribution at cycleMin shift the whole curve based on the cycleMin.

Element Detail

cycleDeviation

public abstract double cycleDeviation

The allowed deviation from the targeted time, in %.

cycleType

public abstract CycleType cycleType

The type of cycle to be used. This is either think or cycle time.

Default:

com.sun.faban.driver.CycleType.CYCLETIME

cycleMin

public abstract int cycleMin

The min cycle or think time in milliseconds.

Default:

0

truncateAtMin

public abstract boolean truncateAtMin

Whether to truncate the distribution at cycleMin shift the whole curve based on the cycleMin. The frequency at min will be high but the curve does not change from where cycleMin is 0. If that's not acceptable, set truncateAtMin to false and the whole distribution will shift to the right, starting at min.

Default:

true

cycleMean

public abstract int cycleMean

The mean cycle or think time in milliseconds.

Default:

1000

cycleMax

public abstract int cycleMax

The max cycle or think time in milliseconds, defaults to 5xcycleMean.

Default:

-1
