Hello,
This is a question about the standard DSF VM adapters.
I was wandering why StackFramesVMNode.IncompleteStackVMContext does not derive from IDMVMContext?
When IncompleteStackVMContext is used as a viewer input for the other views, we will end up with CompositeDMVMContexts created with empty list of parents.
Later on, my _expression_ service will be called with that CompositeDMVMContext.
Now the CompositeDMVMContext derives from IDMContext, but has no parents.
In my DM hierarchy I was expecting to be able to get to my root parent, but when <…more frames…> node is selected I cannot get to it.
I see that in GDB’s _expression_ services MIExpressions there is a special handle for that:
inside CreateExpression, if we can’t get to an execution context from the DM context a InvalidContextExpressionDMC is created.
I can do the same, but I wanted to make sure that StackFramesVMNode.IncompleteStackVMContext intentionally does not derive from IDMVMContext.
There can be other clients that receives IDMContext with no parents, and they have to accommodate for that.
I guess the generic question, is it OK for DSF to populate flexible threes with VM contexts that are not IDMVMContexts ?
Thanks
Dobrin
