API reference

• invokeTask(function, priority = 0, name = null, doCheckTask = true): string
  Invokes the void function with given number priority (less is better).
  Name is optional
  doCheckTask disables invoking the check of queued tasks after insert.
  Returns the name of the generated repeated Task

• run(function, name = null): string
  Alias for invokeTask, without optional parameters .
  Returns the name of the generated repeated Task

• invokeScheduledTask(function, delay, priority = 0, name = null, doCheckTask = true): string
  Similar to invokeTask. The delay parameter gives the milliseconds timeout until the task is run.
  Returns the name of the generated repeated Task

• setTimeout(function, delay, name = null): string
  Alias for invokeScheduledTask, without optional parameters .
  Returns the name of the generated repeated Task

• invokeRepeatedTask(func, delay, zeroTimeRun = true, priority = 0, name = null, doCheckTask = true): string
  Repeats calling function every delay milliseconds.
  zeroTimeRun Boolean switch do invoke first iteration immediately.
  Returns the name of the generated repeated Task

• setInterval(function, delay, zeroTimeRun = false, name = null): string
  Alias for invokeRepeatedTask, without optional parameters.
  Returns the name of the generated repeated Task

• removeScheduledTask(name: string)
  Removes the scheduled task from the queue.

• clearTimeout(name: string)
  Alias for removeScheduledTask

• removeRepeatedTask(name: string)
  Remves the repeated task from queue.
  Alias for removeScheduledTask

• clearInterval(name: string)
