Interface TesTimesInterface

public interface TesTimesInterface

This interface will be used to organize and manage test times that are measured for specific operations. The user will utilze System.nanoTime() to measure the teat time of an operation.

Before the operation is started, you can obtain the start time:
startTime = System.nanoTime().

After the operation is completed, you can obtain the end time:
endTime = System.nanoTime().

Test Time is then:
testTime = endTime - startTime.

Method Summary

Modifier and Type	Method and Description
void	addTestTime(long testTime) This method is used to add a test time.
double	getAverageTestTime() This method is used to obtain the average test time.
long	getLastTestTime() This method is used to retrieve the last test time.
long[]	getTestTimes() This method returns an array of long values representing the last 10 test times.
void	resetTestTimes() This method is used to reset all 10 linear search times to zero.

Method Detail

getLastTestTime

long getLastTestTime()

This method is used to retrieve the last test time. If no test time has been added, the method will return a zero.

Returns:

The last test time, in nanoseconds, or zero.

getTestTimes

long[] getTestTimes()

This method returns an array of long values representing the last 10 test times. If less than 10 test times are available, the remaining test times should be zero. If more than 10 test times have been added, the array should contain the last 10 test times.

Returns:

An array of long values representing the last 10 test times.

resetTestTimes

void resetTestTimes()

This method is used to reset all 10 linear search times to zero.

addTestTime

void addTestTime(long testTime)

This method is used to add a test time.

Parameters:

testTime - a long value representing the test time in nanoseconds.

getAverageTestTime

double getAverageTestTime()

This method is used to obtain the average test time. The method should average all the non-zero test times that are available. If no test times are available, the method returns a zero.

Returns:

A double value representing the average of all the non-zero test times, or zero.
