monitoring the progress of loading resources [message #507629]

Hi,

I was wondering if there's a way to hook a progress monitor for loading resources. Currently I am working with a quite big model that's partitioned in several files. Loading a resource using

Resource resource = resourceSet.getResource(uri, true);

can take up to 40 seconds in my case.

The Javadoc of Resource.load(options) mentions the Eclipse progress monitor but I couldn't find an example where it's actually used.

Can someone provide a small sample or a hint how to do it?

Thanks in advance!

Rob

Robert,

XSDResourceImpl shows an example.

I've had a look at that class before my post. Since you point me to it again, I suppose the functionality has to be provided by a custom Resource implementation. I was hoping it's already there and I just needed the right options key. So, in my case I'll need to provide a custom GMFResource and a custom LazyLinkingResource then.

Regards
Rob

Robert,

You might be able to make due with a OPTION_RESOURCE_HANDLER if they're
derived from XMLResource. Given we have a ProgressMonitor API in EMF
itself, one could imagine making better use of that in the base framework...
