Class NestedProfilerDemo


public class NestedProfilerDemo extends Object
This demo illustrates usage of SLF4J profilers.

We have been given the task of generating a large number, say N, of random integers. We need to transform that array into a smaller array containing only prime numbers. The new array has to be sorted.

While tackling this problem, we would like to measure the time spent in each subtask.

A typical output for this demo would be:

 + Profiler [DEMO]
|-- elapsed time                       [RANDOM]     0.089  seconds.
|---+ Profiler [SORT_AND_PRUNE]
    |-- elapsed time                         [SORT]     0.221  seconds.
    |-- elapsed time             [PRUNE_COMPOSITES]    11.567  seconds.
    |-- Subtotal                   [SORT_AND_PRUNE]    11.788  seconds.
|-- elapsed time               [SORT_AND_PRUNE]    11.788  seconds.
|-- Total                                [DEMO]    11.877  seconds.
