Holds a DAP4 enumeration.
- Note
- When constructed a type for the Enum must be specified. If it is not an integer type, the Enum will use unsigned int 64. This is not the same as the enumeration type that is defined using the Enumeration XML element in the DMR - that information is stored in additional fields and used for checking values and printing the variable's declaration, but not for the internal storage of values.
- Todo
- Note the hack to remove the union...

- Note
- The private method m_type_width() returns the byte width used for the on-the-wire representation of values.
- Returns
- The number of bytes used by a value.
