#define STATUSCODE_ENUM_IMPL

(

)

BOOST_PP_OVERLOAD( STATUSCODE_ENUM_IMPL_, __VA_ARGS__ )( __VA_ARGS__ )

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

Parameters

ENUM	enum class
CATEGORY	(optional) category, otherwise use default StatusCode category

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

Function Documentation

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

inline

Ternary AND operator.

Definition at line 342 of file StatusCode.h.

{ return lhs &= rhs; }

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

inline

Boolean AND assignment operator.

Definition at line 348 of file StatusCode.h.

{ return lhs &= sc.isSuccess(); }

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

Definition at line 307 of file StatusCode.h.

{
  lhs.m_checked = true;
  rhs.m_checked = true;
  return ( lhs.m_code == rhs.m_code ) &&
         ( lhs.m_code == static_cast<StatusCode::code_t>( StatusCode::ErrorCode::SUCCESS ) ||
           lhs.m_code == static_cast<StatusCode::code_t>( StatusCode::ErrorCode::FAILURE ) ||
           ( lhs.m_cat == rhs.m_cat ) );
}

StatusCode operator| ( StatusCode  lhs, const StatusCode &  rhs  )

inline

Ternary OR operator.

Definition at line 345 of file StatusCode.h.

{ return lhs |= rhs; }

bool& operator|= ( bool &  lhs, const StatusCode &  sc  )

inline

Boolean OR assignment operator.

Definition at line 351 of file StatusCode.h.

{ return lhs |= sc.isSuccess(); }
