[fpc-devel] Overloading methods of a parent class

I'm currently trying to implement the overloading of methods in class
helpers, but I now have the problem that I don't know where I should
touch the compiler.
So my question is the following: How does overloading methods that are
defined in different (but related) classes work in the compiler?
TClass1 = class
procedure Test(aValue: Integer); overload;
TClass2 = class(TClass1)
procedure Test(aValue: String); overload;
Where does the compiler decide which method to call? And how does the
compiler know which methods are available?
The latter question can be understand as: Does the compiler search the
correct symtable (in this case that for TClass1) when it parses the
factor "c.Test" or does it resolve that already when parsing the
definition of TClass2?
I'll continue searching the correct spot nevertheless.
