Method Name:
empty
Method Signature:
empty()
Return Value:
Returns False if the scheduler has one or more events to execute.
Returns True, if the internal queue of the scheduler is empty.
Overview:
The empty() method checks whether the internal queue of a scheduler instance is empty or not and it returns True if the queue is empty. Returns False otherwise.
Example:
|
# Example Python program to check whether the internal queue of the scheduler is empty import sched import time
# The function that defines the task def taskFunction(eventid): print("Executing event with event id:%d"%eventid);
taskScheduler = sched.scheduler(time.time, time.sleep);
# Add tasks to the scheduler t1 = taskScheduler.enter(10, 1, taskFunction, (1,)); t2 = taskScheduler.enter(5, 1, taskFunction, (2,));
# Check whether the scheduler's queue is empty isEmpty = taskScheduler.empty(); print("Scheduler has one or more tasks to execute:%s"%(not isEmpty));
taskScheduler.run();
# Check whether the scheduler's queue is empty isEmpty = taskScheduler.empty(); print("Scheduler has one or more tasks to execute:%s"%(not isEmpty)); |

Scheduler has one or more tasks to execute:True Executing event with event id:2 Executing event with event id:1 Scheduler has one or more tasks to execute:False |
