Method Detail

getLastRunTime

public long getLastRunTime()

Description copied from interface: RuntimeInterface

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

Specified by:

getLastRunTime in interface RuntimeInterface

Returns:

The last runtime, in nanoseconds, or zero.

getRunTimes

public long[] getRunTimes()

Description copied from interface: RuntimeInterface

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

Specified by:

getRunTimes in interface RuntimeInterface

Returns:

An array of long values representing the last 10 runtimes.

resetRunTimes

public void resetRunTimes()

Description copied from interface: RuntimeInterface

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

Specified by:

resetRunTimes in interface RuntimeInterface

addRuntime

public void addRuntime(long runTime)

Description copied from interface: RuntimeInterface

This method is used to add a runtime.

Specified by:

addRuntime in interface RuntimeInterface

Parameters:

runTime - a long value representing the runtime in nanoseconds.

getAverageRunTime

public double getAverageRunTime()

Description copied from interface: RuntimeInterface

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

Specified by:

getAverageRunTime in interface RuntimeInterface

Returns:

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