void * GetRawContent () const
std::size_t GetSize () const
virtual bool IsMappable () const
 Derived, typed classes tell whether the on-storage layout is bitwise identical to the memory layout. More...

RColumnElementBaseoperator= (RColumnElementBase &&other)=default
virtual void Pack (void *destination, void *source, std::size_t count) const
 If the on-storage layout and the in-memory layout differ, packing creates an on-disk page from an in-memory page. More...
void ReadFrom (void *source, std::size_t count)
 Set the column element or an array of elements from the memory location source. More...
virtual void Unpack (void *destination, void *source, std::size_t count) const
 If the on-storage layout and the in-memory layout differ, unpacking creates a memory page from an on-storage page. More...
void WriteTo (void *destination, std::size_t count) const
 Write one or multiple column elements into destination. More...
