Hi Manuel,
<div><br>
</div>
<div>when the command is finished, 'loop' will return immediately.</div>
<div><br>
</div>
<div>Alternatively you can also use 'block' instead. 'block' lets you specify a maximum time </div>
<div>you want to wait for the command to finish. 'loop' is the same, you can just have a bit </div>
<div>more feedback of what time has passed. Both will return immediately when the command </div>
<div>is finished.</div>
<div><br>
</div>
<div>There's no need for Thread.sleep() etc.</div>
<div><br>
</div>
<div>Hope that makes it a bit clearer.</div>
<div><br>
</div>

<div>Dear all,</div>
<div><br>
</div>
<div>I'm wondering what's the correct way to handle async callbacks, e.g. deleting an object, as a non-async call</div>
<div>(wait until the command has been executed).</div>
<div><br>
</div>
<div>The docu for deleting an object:</div>
<div><a href="https://docs.openmicroscopy.org/omero/5.4.0/developers/Java.html#delete-data" target="_blank">https://docs.openmicroscopy.<wbr>org/omero/5.4.0/developers/<wbr>Java.html#delete-data</a><br>
</div>
<div><br>
</div>
<div>calls loop(10,500) to wait until it is finished. </div>
<div>- why do you wait 10 times 500 and not one time 5000 ?</div>
<div>- if the call is finished after a few loops, will it still do the other waits?</div>
<div>- is there a guaranty that after the loop call the command has been finished?</div>
<div><br>
</div>
<div>My goal is to wait until the call is finished.</div>
<div>What about <a href="http://s.th/" target="_blank">s.th</a>. like</div>
<div><br>
</div>
<div>CmdCallbackI callback = dm.delete(context, object);<br>
</div>
<div>while (callback.getResponse()!=null) {</div>
<div> Thread.sleep(100);</div>
<div>}</div>
<div>?</div>
<div><br>
</div>
<div>Thanks for your help!</div>
<div><br>
</div>
