Constructor Detail

TimeStatisticImpl

public TimeStatisticImpl(java.lang.String name,
                         java.lang.String units,
                         java.lang.String description)

Create a TimeStatistic
Parameters:: name - the name of the state; units - the units of the stat; description - a description of the stat

Method Detail

getCount

public long getCount()

Description copied from interface: TimeStatistic (src)

Number of times the operation was invoked since the beginning of this measurement.

Specified by:: getCount in interface TimeStatistic (src)

Returns:: The number of times a time measurements was added

getMinTime

public long getMinTime()

Description copied from interface: TimeStatistic (src)

The minimum amount of time taken to complete one invocation of this operation since the beginning of this measurement.

Specified by:: getMinTime in interface TimeStatistic (src)

Returns:: The minimum time added since start of the measurements

getMaxTime

public long getMaxTime()

Description copied from interface: TimeStatistic (src)

The maximum amount of time taken to complete one invocation of this operation since the beginning of this measurement.

Specified by:: getMaxTime in interface TimeStatistic (src)

Returns:: The maximum time added since start of the measurements

getTotalTime

public long getTotalTime()

Description copied from interface: TimeStatistic (src)

This is the sum total of time taken to complete every invocation of this operation since the beginning of this measurement. Dividing totalTime by count will give you the average execution time for this operation.

Specified by:: getTotalTime in interface TimeStatistic (src)

Returns:: The sum of all the time added to the measurements since it started

getRequestRate

public double getRequestRate()

Returns:: The request rate which is the number of counts divided by the time elapsed since the time measurements started

toString

public java.lang.String toString()

Overrides:: toString in class StatisticImpl (src)

Returns:: Debug Information about this instance

add

public void add(long pTime)

Adds a Statistic Information about the elapsed time an action observed by this instance took.

Parameters:: pTime - Time elapsed to added to a statistics

reset

public void reset()

Resets the statistics to the initial values

Overrides:: reset in class StatisticImpl (src)

set

public void set(long count,
                long minTime,
                long maxTime,
                long totalTime)

Set all TimeStatistic values.

Parameters:: count - the invocation count; minTime - the min time for an invocation; maxTime - the max time for an invocation; totalTime - the total time for all invocations
