Documentation

A simple timer class. You can derive a subclass of Timer to provide a simple mechanism for scheduling events:

$self sched $delay -- causes "$self timeout" to be called $delay seconds in the future $self cancel -- cancels any pending scheduled callback

Timer instproc init { ns }

Timer instproc sched delay
sched is the same as resched; the previous setting is cancelled and another event is scheduled. No state is kept for the timers. This is different than the C++ timer API in timer-handler.cc,h; where a sched aborts if the timer is already set. C++ timers maintain state (e.g. IDLE, PENDING..etc) that is checked before the timer is scheduled.

Timer instvar ns_

Timer instvar id_

Timer instproc destroy {}

Timer instproc cancel {}

Timer instproc resched delay
resched and expire are added to have a similar API to C++ timers.

Timer instproc expire {}
the subclass must provide the timeout function
