Member Function Documentation

copy()

template<typename Last >

static void join::details::VariantHelper< Last >::copy ( std::size_t , const void * oldData, void * newData )

inlinestatic

external routine to copy one object to an other.

Parameters

inlinestatic

external routine to destroy the object.

Parameters

index	object data type index.
data	storage pointer.

equal()

template<typename Last >

inlinestatic

external routine to compare if one object is equal to an other of same type.

Parameters

index	object data type index.
data	storage pointer.
otherData	other storage pointer.

Returns

true if equal, false otherwise.

lower() [1/2]

template<typename Last >

inlinestatic

external routine to compare if one object is lower than an other of the same type.

Parameters

index	object data type index.
data	storage pointer.
otherData	other storage pointer.

Returns

true if lower than, false otherwise.

lower() [2/2]

template<typename Last >

template<typename T = Last, typename std::enable_if_t<!std::is_null_pointer< T >::value > * = nullptr>

static bool join::details::VariantHelper< Last >::lower ( std::size_t , const void * data, const void * otherData )

inlinestatic

external routine to compare if one object is lower than an other of the same type.

Parameters

index	object data type index.
data	storage pointer.
otherData	other storage pointer.

Returns
