Member Typedef Documentation

IsValid

using IsValid = typename std::conditional<IsValueTypeLegal<VALUETYPE, KEYTYPE>(), std::true_type, std::false_type>::type

Use "ValidKeyValuePairTrait<ILLEGALTYPES...>::IsValid<VALUETYPE, KEYTYPE>" to get compile time validation of the type pair.

Member Function Documentation

IsValueTypeLegal() [1/3]

static constexpr Bool IsValueTypeLegal ( const KEYTYPE &  key, const VALUETYPE &    )

staticconstexpr

Validation using deduced types, i.e. run type validation on lvalue, rvalue, ...

IsValueTypeLegal() [2/3]

static constexpr Bool IsValueTypeLegal ( const KEYTYPE &  )

staticconstexpr

Validation using deduced key type. Allows validation directly using attribute FId variables.

IsValueTypeLegal() [3/3]

static constexpr Bool IsValueTypeLegal ( )

staticconstexpr

Validation using explicit types.
