SimpleTimer

All Superinterfaces:

Counting, Metric
```
public interface SimpleTimer
extends Metric, Counting
```
A simple timer metric which tracks elapsed time durations and count. This is a lightweight alternative to (@link Timer). The simple timer measures duration in nanoseconds.

- Method Detail
  - update
```
void update(java.time.Duration duration)
```
    Adds a recorded duration.
    
    Parameters:
    
    duration - the length of the duration
  - time
```
<T> T time(java.util.concurrent.Callable<T> event)
    throws java.lang.Exception
```
    Times and records the duration of event.
    
    Type Parameters:
    
    T - the type of the value returned by event
    
    Parameters:
    
    event - a Callable whose Callable.call() method implements a process whose duration should be timed
    
    Returns:
    
    the value returned by event
    
    Throws:
    
    java.lang.Exception - if event throws an Exception
  - time
```
void time(java.lang.Runnable event)
```
    Times and records the duration of event.
    
    Parameters:
    
    event - a Runnable whose Runnable.run() method implements a process whose duration should be timed
  - time
```
SimpleTimer.Context time()
```
    Returns a new SimpleTimer.Context.
    
    Returns:
    
    a new SimpleTimer.Context

  - getElapsedTime
```
java.time.Duration getElapsedTime()
```
    Returns the total elapsed timing durations of all completed timing events that are recorded with update(Duration).
    
    Returns:
    
    the elapsed time duration
  - getCount
```
long getCount()
```
    Description copied from interface: Counting
    
    Returns the current count.
    
    Specified by:
    
    getCount in interface Counting
    
    Returns:
    
    the current count
  - getMaxTimeDuration
```
java.time.Duration getMaxTimeDuration()
```
    Get the maximum recorded time duration of the SimpleTimer for the previously completed full minute.
    This represents the highest timed duration in the last completed full minute. For example if the last completed full minute recorded durations of 12 seconds, 9 seconds and 1 second the largest value is 12 seconds. If no time duration has been recorded in the last completed full minute then a null is returned. If there has only been one time duration recorded in the last completed full minute then this value will be returned by both getMaxTimeDuration() and getMinTimeDuration()
    
    Returns:
    
    The maximum recorded time duration in the previously completed full minute or null if no values were recorded
  - getMinTimeDuration
```
java.time.Duration getMinTimeDuration()
```
    Get the minimum recorded time duration of the SimpleTimer for the previously completed full minute.
    This represents the lowest timed duration in the last completed full minute. For example if the last completed full minute recorded durations of 12 seconds, 9 seconds and 1 second the lowest value is 1 second. If no time duration has been recorded in the last completed full minute then a null is returned. If there has only been one time duration recorded in the last completed full minute then this value will be returned by both getMaxTimeDuration() and getMinTimeDuration()
    
    Returns:
    
    The minimum recorded time duration in the previously completed full minute or null if no values were recorded
