Lua:Class:Thread

Thread class: (Inheritance: Object)

The thread class executes the given function in another thread using the systems thread mechanism

Creation

createThread(function(Thread,...), ...)

returns the Thread class object

Properties

Name : string

This name will be shown when the thread terminated abnormally

Finished : boolean

true if the thread has reached the end. Do not rely on this if the thread is freeOnTerminate(true) (which is the default)

Terminated : function(timer)

true if the Terminate method has been called

Methods

freeOnTerminate(state) :

When set to true the thread object will free itself when the function ends (default=true)

Note: Use this only from inside the thread function as the thread might have already terminated and freed itself when called

synchronize(function(thread,...), ...) 

given function's return value

Usually for GUI access. Called from inside the thread

This will cause the thread to get the main thread to execute the given function and wait for it to finish.

Returns the return value of the given function

waitfor() :

Waits for the given thread to finish (Not recommended to call this from inside the thread itself)

suspend()

Suspend the thread's execution

resume() :

Resume the thread;s executionmm

terminate()

Tells the thread it should terminate. The Terminated property will become true

Examples

 local thread = createThread(function(timer)
   local i = 0
   while i < 100 do
     i = i + 1
     print(i)
     sleep(100)
   end
   return 50
 end)

 -- run given function after a delay
 local function delayed(func, delay)
   if type(func) ~= 'function' then return end
   if type(delay) ~= 'number' then delay = 1000 end
   local t = createTimer()
   t.Interval = delay
   t.OnTimer = function(t)
     -- only run once by destroying the timer object
     t.destroy()
     func()
   end
 end

 delayed(function()
   print('suspending')
   thread.suspend()
   delayed(function()
     print('resuming')
     thread.resume()
   end, 3500)
 end, 5000)
