## Detailed Description

## Member Function Documentation

## ◆ canCancel()

virtual bool zyppng::AsyncOpBase::canCancel | ( |  | ) |
| inline virtual

Should return true if the async op supports cancelling, otherwise false

Definition at line 96 of file asyncop.h.

## ◆ cancel()

virtual void zyppng::AsyncOpBase::cancel | ( |  | ) |
| inline virtual

Explicitely cancels the async operation if it supports that, otherwise throws a CancelNotImplementedException

Generally every AsyncOp HAS TO support cancelling by releasing the last reference to it, however in some special cases we need to be able to cancel programatically from the backends and notify the frontends by returning a error from a AsyncOp.

Definition at line 108 of file asyncop.h.

## ◆ sigStarted()

SignalProxy< void()> zyppng::AsyncOpBase::sigStarted | ( |  | ) |
| inline

Signal that is emitted once the AsyncOp is started

Definition at line 115 of file asyncop.h.

## ◆ sigProgress()

SignalProxy< void(const std::string &, int, int)> zyppng::AsyncOpBase::sigProgress | ( |  | ) |
| inline

Signal that might be emitted during operation of the AsyncOp, not every AsyncOp will use this

Definition at line 123 of file asyncop.h.

## ◆ sigReady()

SignalProxy< void()> zyppng::AsyncOpBase::sigReady | ( |  | ) |
| inline

Signal that is emitted once the AsyncOp is ready and no callback was registered with onReady

Definition at line 131 of file asyncop.h.
