Method Detail

measureExecutionTime

public static <T> T measureExecutionTime(String measurementName,
                                         java.util.function.Supplier<T> supplier)

Allows to measure the execution time of a method by wrapping it's call. Logged result in microseconds.

Type Parameters:

T - return type of the measured method

Parameters:

measurementName - name that allows to distinguish this measurement from others

supplier - measured method

Returns:

the acctual result of measured method

measureAvrgExecutionTime

public static <T> T measureAvrgExecutionTime(String measurementName,
                                             java.util.function.Supplier<T> supplier)

Allows to measure the average execution time of a method by wrapping it's call. Logged result in microseconds. Default value is 100 runs.

Type Parameters:

T - return type of the measured method

Parameters:

measurementName - name that allows to distinguish this measurement from others

supplier - measured method

Returns:

the acctual result of measured method

measureExecutionTime

public static <T> T measureExecutionTime(String measurementName,
                                         TimeUnit timeUnit,
                                         java.util.function.Supplier<T> supplier)

Allows to measure the execution time of a method by wrapping it's call. Logged result in microseconds.

Type Parameters:

T - return type of the measured method

Parameters:

measurementName - name that allows to distinguish this measurement from others

timeUnit - a time unit to present the result

supplier - measured method

Returns:

the acctual result of measured method

measureAvrgExecutionTime

public static <T> T measureAvrgExecutionTime(String measurementName,
                                             int numberOfRuns,
                                             TimeUnit timeUnit,
                                             java.util.function.Supplier<T> supplier)

Allows to measure the average execution time of a method by wrapping it's call. Logged result in microseconds. Default value is 100 runs.

Type Parameters:
