Create a DelayedFuture that executes the supplied function after the given delay
Create a DelayedFuture that executes the supplied function after the given delay
the time from now to delay execution
the function to execute
a DelayedFuture that can be used to extract result or cancel (only before it has been started)
if the task cannot be scheduled for execution
Creates a PeriodicTask that executes first after the given initial delay, and subsequently with the given period.
Creates a PeriodicTask that executes first after the given initial delay, and subsequently with the given period. PeriodicTask may stopped using the cancel method. If a failure occurs while processing the task, the task is automatically cancelled. If any execution of this task takes longer than its period, then subsequent executions may start late, but will not concurrently execute.

the period between successive executions
