Usage

Threadpool

• Implement Runnable interface for tha task that needs to be executed. For example

  type MyTask struct { }
   
  func (t *MyTask) Run(){
    // Do your task here
  }
   
  

• Create instance of ThreadPool with number of workers required and the task queue size

  pool := threadpool.NewThreadPool(200,1000000)
  

• Create Task and execute

  task:=&MyTask{}
  err := pool.Execute(task)
  

• Using Callable task

  type MyTaskCallable struct { }
  
  func (c *MyTaskCallable) Call() interface{} {
    //Do task 
    return result
  }
  
  //Execute callable task
  task := &MyTaskCallable{}
  future, err := pool.ExecuteFuture(task)
  
  //Check if the task is done
  isDone := future.IsDone() // true/false
  
  //Get response , blocking call
  result := future.Get()
  
  

• Close the pool

  pool.Close()
  

Scheduled threadpool

• Create instance of ScheduledThreadPool with number of workers required

  schedulerPool:= threadpool.NewScheduledThreadPool(10)
  

• Create Task and schedule

  task:=&MyTask{}
  pool.ScheduleOnce(task, time.Second*20) // Time delay is in seconds only as of now
  

• Close the pool

  pool.Close()
