Method Details

run

public static double run(Runnable r)

Time how long it takes to execute Runnable r. Time is calculated in nano seconds and returned as milliseconds.

Parameters:

r - - Runnable to time

Returns:

elapsed time in milliseconds

See Also:

• run(Runnable, int)

run

public static double run(Runnable r,
 int n)

Time how long it takes to execute Runnable r, n amount of times. Then calculate the average elapsed time taken.

Parameters:

r - - Runnable to time

n - - Amount of times to run

Returns:

average elapsed time milliseconds

See Also:

• run(Runnable)

runFormatMS

public static String runFormatMS(Runnable r)

Time how long it takes to execute Runnable r. Time is calculated in nano seconds and returned as a formatted string with two decimal places.

This method is effectively equivalent to

 MethodTimer.runFormatMS(r, 2)
 

Parameters:

r - - Runnable to time

Returns:

formatted string with two decimal places

See Also:

• runFormatMS(Runnable, int)
• runFormatMS(Runnable, int, int)

runFormatMS

public static String runFormatMS(Runnable r,
 int decimals)

Time how long it takes to execute Runnable r. Time is calculated in nano seconds and returned as a formatted string with decimals decimal places.

This method is effectively equivalent to

 String.format("%." + decimals + "f ms", run(r))
 

Parameters:

r - - Runnable to time

decimals - - Amount of decimal places to format

Returns:

formatted string with decimals decimal places

See Also:

• runFormatMS(Runnable)
• runFormatMS(Runnable, int, int)

runFormatMS

public static String runFormatMS(Runnable r,
 int n,
 int decimals)

Time the average elapsed time it takes to execute Runnable r, n amount of times. Time is calculated in nano seconds and returned as a formatted string with decimals decimal places.

This method is effectively equivalent to

 String.format("%." + decimals + "f ms", run(r, n));
 

Parameters:

r - - Runnable to time

n - - Amount of times to execute r

decimals - - Amount of decimal places to format

Returns:

formatted string with decimals decimal places
