How to know when attribute processing is done, even with no attributes specified
Hi all,
In the C API there is the attr_args_process function that I call to process the attributes entered in an object box. In Java this happens automatically, from what I can see sometime after the constructor of the object has completed.
I would however like to know when the processing of attributes is complete, so that I can take action if an attribute has -not- been specified. Is there a function that can notify me when this has been done?
Many thanks,
Mattijs
Off the top of my head, I would be inclined to initialize _all_ values at the beginning of the new() method (before attribute processing happens), then let the attribute processing handle any overrides specified by @attribute parameters in the object initialization.
Yeah, so some attibutes may be set up twice (first to the default and then by the user override with an @attribute). Are you in that much of a hurry to worry about it?-)
Or am I missing something?
Hi Peter!
Thanks for your reply. In this case initializing the attributes twice is exactly what I want to try to prevent. I'm working on my networking objects and depending on the attribute a server socket is initialized. Preferably I wouldn't do that twice.
Btw I found a workaround for now: setting a Qelem at the end of the constructor to call my init method. It looks like the attribute setting has been done once the queue reaches it.
Best,
Mattijs
Hi Mattijs,
there is another way- probably more reliable:
declare the attribute with a custom getter and setter methods. When the object is instantiated the setter will be called with the right right attribute value.

Hi Jan,
Thanks for your reply, although I think you misunderstood the problem; I do have custom getters and setters, but I need to know when they are called during the initialization sequence..
Thanks,
Mattijs
