Re: [platform-debug-dev] Implementing IWatchExpressionDelegate

Generally, you can retrieve the variables contained in a variable by using 
IVariable.getValue().getVariables(). I.e. a value representing a data 
structure may contain more variables. However, its entirely up to your 
debug model/language to determine what sort of scoping rules exist, and if 
B should be visible in the context of A.

[platform-debug-dev] Implementing IWatchExpressionDelegate

Hello,

I would like to use Watch Expressions in my Debug Platform project. 
Looking in the WatchExpressionDelegate I get

public void evaluateExpression(String expression, IDebugElement context, 
IWatchExpressionListener listener)

whereby expression is the Variable Name of the Variable Window and 
context is a StackFrame of the surrounding context.

My problem is that context has all Variables (of course according to 
it's name) of the surrounding Stack Frame. Since my variable names (of 
the variable view) are only unique on their first level e.g.,

uniqueID variable "A" -->(unfolding a "complex" variable)--> "B" 
("living" inside of "A").

I am able to get the value of the expression on the first level (by 
traversing the Stackframe) - but not the value of variable B since B 
might occur multiple times in the Stackframe.

Is there a ("direct") way to get the value of "B"?

Greetings,

    Ralf
