Detailed Description

template<typename def, typename inner = typename def::type>
class dds::core::safe_enum< def, inner >

<<value-type>> Provides a safe, scoped enumeration based on def::type

The purpose of this class is to provide a C++11-style enum class, where the enumeration constants are scoped.

Template Parameters

def	A struct containing the actual enumeration, def::type

See for example dds::core::policy::ReliabilityKind. The actual enumeration is in dds::core::policy::ReliabilityKind_def, but the application only needs to use the former:

using dds::core::policy::ReliabilityKind;

ReliabilityKind kind = ReliabilityKind::RELIABLE;

Constructor & Destructor Documentation

template<typename def, typename inner = typename def::type>

dds::core::safe_enum< def, inner >::safe_enum ( )

inline

Default constructor doesn't initialize the underlying enumeration.

For consistency with the behavior of C++11 class enum, this constructor doesn't initialize the enumeration.

template<typename def, typename inner = typename def::type>

dds::core::safe_enum< def, inner >::safe_enum ( inner_enum  v )

inline

Copy constructor.
