Extendening/wrapping Logger?

[s243a]

The code shown bellow was given as an example of how to extend Loger what I 
don't get is why logger was made a static field. Would this mean you would need 
a separate class for every instance?

exception std::out_of_range in StringHelper::startsWith

[Thorsten Schöning]

Hello,

I get an out_of_range exception everytime I use a logger which name is
longer than the name of the root logger and wonder if anyone else ran
into this problem, too. We use a pretty old Borland Builder 5, may it
be an implementation issue of the stl? Reading how
basic_string::compare works for other implementations the current
startWith should work, in my opinion.

I had to make the following changes:

Index: stringhelper.cpp
===
--- stringhelper.cpp(Revision 1652)
+++ stringhelper.cpp(Arbeitskopie)
@@ -79,6 +79,11 @@
 
 bool StringHelper::startsWith(const LogString s, const LogString prefix)
 {
+if (s.length()  prefix.length())
+{
+  return false;
+}
+
 return s.compare(0, prefix.length(), prefix) == 0;
 }

Mit freundlichen Grüßen,

Thorsten Schöning
