Detailed Description

template<typename EnumType>
class WholeEnum< EnumType >

Class expressing a continuous range of a whole enum for range-for expressions

Class for iterating all enum values, from EnumType::enumBegin_ up to, but not including, EnumType::enumEnd_.

This class requires that:

• the underlying enum values be represented by continuous values of an integral type.
• both enumBegin_ and enumEnd_ markers must be present as EnumType values;
• enumBegin_ must have the same representation as the first element of the enum
• enumEnd_ must have a representation that is one past the last user-accessible value of the enum.

Typical use:

enum class EnumType {
  enumBegin_ = 0,
  first_value = enumBegin_,
  second_value,
  enumEnd_
};
for(auto enumvalue : WholeEnum<EnumType>()) {
  do_stuff();
}
