From GiderosMobile
Available since: Gideros 2017.8
Class: Core
Description
Returns an associative array of tables describing CPU usage of lua functions.
(table) = Core.profilerReport()
Each table in the array is indexed by a unique function id and has the following content:
- name - Name of the function
- time - Total time spent in the function (seconds)
- count - Number of times this function was called
- callers - A table containing the same information has above for each function which called this one
Return values
Returns (table) table with profiling data
Example
max = 10000
calls = 10
a = -458
local abs=math.abs
function test1()
for loop=1,max do
local sign=math.abs(a)/a
end
end
function test2()
for loop=1,max do
local sign=1
if a<0 then sign=-1 end
end
end
function test3()
for loop=1,max do
local sign=a < 0 and -1 or 1
end
end
Core.profilerReset()
Core.profilerStart()
for loop = 1, calls do
test1()
test2()
test3()
end
Core.profilerStop()
-- print the results of the profiler
result = Core.profilerReport()
print("Number of tests:", max*calls)
for k,v in pairs(result) do
local found=false
for k2,v2 in pairs(v) do
if found and k2=="time" then print(v1,v2) end
if k2=="name" and string.sub(v2,1,4)=="test" then v1=v2 found=true end
end
