Detailed Description

template<typename E>
class ccxx::EnumMap< E >

A bidirectional mapping between enum values and static string constants.

An EnumMap can be constructed as follows:

enum FileType { TypeFile, TypeDirectory, TypeSymLink };

EnumMap<FileType> fileTypeMap;
fileTypeMap.add(TypeFile,      "file")
           .add(TypeDirectory, "directory")
           .add(TypeSymLink,   "symlink");
