Question about about LintRule

> Hello,
> I'm currently looking a bit at how lint rules work. The current example I'm
> looking at is:
>  RBTempVarOverridesInstVarRule
>        => this rule check for tmp variables that override an existing
> instance variable in the class
>        => when such a case is detected, the result is stored like that:
>                         result
>      addClass: aContext selectedClass
>      selector: aContext selector.
>         result addSearchString: varName.
>        => so, all variables are just stored one by one in a collection
> ('searchString') and never linked to the method in which the problem
> happened.
> What I wonder is: How are you able then to display, as result, a list of
> method, and for each of them to highligth the 'problematic' tmp variable?
> How do you make the the link between a class-selector from the result, and,
> the variable name causing the problem for this selector?
