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
end
