Detailed Description

New lexcical_cast header.

For debugging you can include this header in a namespace (to honor ODR) and have a set of functions that throws exceptions instead of doing the real job. This is done for the unit tests but should normally not be done.

Definition in file lexical_cast.hpp.

Macro Definition Documentation

#define DEBUG_THROW

(

id

)

throw id;

#define DEBUG_THROW

(

id

)

Throws an exception for debugging.

Parameters

id	The unique name to identify the function.

Note

this name is a user defined string and should not be modified once used!
