The oslo_vmware.common.loopingcall Module¶

class oslo_vmware.common.loopingcall.DynamicLoopingCall(f=None, *args, **kw)¶

Bases: oslo_vmware.common.loopingcall.LoopingCallBase

A looping call which sleeps until the next known event.

The function called should return how long to sleep for before being called again.

start(initial_delay=None, periodic_interval_max=None)¶

class oslo_vmware.common.loopingcall.FixedIntervalLoopingCall(f=None, *args, **kw)¶

Bases: oslo_vmware.common.loopingcall.LoopingCallBase

A fixed interval looping call.

start(interval, initial_delay=None)¶

oslo_vmware.common.loopingcall.LoopingCall¶

alias of oslo_vmware.common.loopingcall.FixedIntervalLoopingCall

class oslo_vmware.common.loopingcall.LoopingCallBase(f=None, *args, **kw)¶

Bases: object

stop()¶

wait()¶

exception oslo_vmware.common.loopingcall.LoopingCallDone(retvalue=True)¶

Bases: Exception

Exception to break out and stop a LoopingCall.

The poll-function passed to LoopingCall can raise this exception to break out of the loop normally. This is somewhat analogous to StopIteration.

An optional return-value can be included as the argument to the exception; this return-value will be returned by LoopingCall.wait()
