Performance

About

This class can be used to test the performance of code.

API

constructor()

cs.js.Performance.new(func : Callable { ; count : Integer { ; thisObj : Object { ; parameters : Collection }}})

Creates an object whose .alert() and .timePerExecution() functions will execute func.apply(thisObj; parameters) count times.

If count is not passed or is <= 0, it defaults to 1000.

If thisObj and/or parameters are passed, they are passed to func.apply().

Examples

$func:=Formula($1+" "+This.name+"!")
$p:=cs.js.Performance.new(\
  $func; \
  10000; \
  New object("name"; "Laurent"); \
  New collection("Hello"))
$p.alert()

// See the Functor.apply() example for the definition of CollectionOp
$func:=cs.CollectionOp.new("sum")
$p:=cs.js.Performance.new(\
  $func; \
  10000; \
  Null; \
  New collection(1; 2; 3))
$timing:=$p.timePerExecution()

.alert()

.alert()

Shows an alert with the time it took to execute the Callable passed to the constructor.

In the example given in the constructor, the alert will show something like:

10,000 iterations
0.0056 ms per iteration

---

.timePerExecution()

.timePerExecution() : Real

Returns the time it took to execute the Callable passed to the constructor the configured number of times, divided by the number of iterations.
