/** \brief enum to string conversion
|
|
|
|
|
*
|
|
|
|
|
* This is the heart of the 'automatic' enum to string conversion and taken
|
|
|
|
|
* from:
|
|
|
|
|
* <a href="http://www.codeproject.com/KB/cpp/C___enums_to_strings.aspx">http://www.codeproject.com/KB/cpp/C___enums_to_strings.aspx</a>
|
|
|
|
|
*
|
|
|
|
|
* Thanks to Marcos F. Cardoso.
|
|
|
|
|
*
|
|
|
|
|
* With the preprocessor #defines from this file and a special inclusion and
|
|
|
|
|
* enum definition strategy the code for enum to string conversion is
|
|
|
|
|
* automatically created.
|
|
|
|
|
*
|
|
|
|
|
* For an enum of name "MyEnum" the conversion function will be called
|
|
|
|
|
* <code>const char* GetStringMyEnum(MyEnum tagMyEnum);</code>.
