Value:

BOOST_PP_OVERLOAD( STATUSCODE_ENUM_IMPL_, __VA_ARGS__ )( __VA_ARGS__ )

Assign a category to the StatusCode enum declared with STATUSCODE_ENUM_DECL( ENUM ).

Parameters

Value:

const StatusCode::Category& is_StatusCode_enum<ENUM>::instance = StatusCode::default_category();

Value:

const StatusCode::Category& is_StatusCode_enum<ENUM>::instance = CATEGORY{};

Definition at line 288 of file StatusCode.h.

#define STATUSCODE_ENUM_IMPL_2( ENUM, CATEGORY )                                                                       \

Function Documentation

operator==()

bool operator== ( const StatusCode & lhs, const StatusCode & rhs )

inline

Note

For code values 0(FAILURE) and 1(SUCCESS) the category is ignored

e.g. sc==StatusCode::SUCCESS is equivalent to sc.isSuccess() for all categories
