Type: number
(milliseconds)
Default: 3600000 or an hour
delay
holds the time in milliseconds indicates after how much time the scheduler will start.
delay
Type: number
(milliseconds)
Default: 500
delay
indicates the interval (milliseconds) between two job. It throws an error if limit is not already set.
Its stop the scheduler and remove all the task.
Its add a normal/low priority job to scheduler.
Type: number, object, string
value
holds the value which will pass to callback function
Type: function
callback
is the function which will call with passed value
Its add a urgent/high priority job to scheduler.
Type: number, object, string
value
holds the value which will pass to callback function
Type: function
callback
is the function which will call with passed value
Its generate limit for the scheduler perform job in a certain time. It throws an error if totalNumberOfJob is not provided.
Type: number
Indicates the total number of job can completed by this scheduler
Type: number
Default: 0
Indicates the maximum number of normal job can completed by this scheduler
If number of job is greater than limit, it will not perform any job for some time and scheduler will auto restart after the same amount of time, passed when scheduler was created.
