Extension support for EMFCompareStructureMergeViewer [message #1580158]

I would like to perform in my use some actions before calling the compareInputChanged(ComparisonScopeInput input, IProgressMonitor monitor) method of the org.eclipse.emf.compare.ide.ui.internal.structuremergeviewer.EMFCompareStructureMergeViewer class.
But all compareInputChanged methods are private (from my extended class), e.g.,

void compareInputChanged(ComparisonScopeInput input, IProgressMonitor monitor) {
...
}

Is this possible to define them as protected in order to allow subclasses to implement specific behavior?
Or did you have an existing mechanism to do such kind of actions?

Thanks in advance for the support.

Hi,

The EMFCompareStructureMergeViewer class is not meant to be subclassed and we _will_ break its compatibility in future version (whether major or not). What exactly are you trying to achieve? We might be able to point you towards the right APIs, or see what can be opened.

Hello,

thanks for the response.

I want to delay the model loading process in order to perfom it only if needed when opeing the EMF compare editor just before the model difference checking. And I want to reuse the "same" progress monitor (a sub monitor) used by this method for loading the models.

Hi Mr. Goubet,

can you please tell me if you have annother way or "API" to do this kind of action?

FYI, our customer have their own model loading process and requires this kind of action as described before.

Can you please say me what can be done or not?
This will be usefull for us before taking any decisions to check others alternatives or solutions for comparing models.

Thanks in advance!
