Function Documentation

AllocateBytes()

template<typename Type >

auto PackedArray::AllocateBytes

(

size_t

enlarged

)

Allocate a Ptr<Type> holding at least enlarged bytes.

Usage: AllocateBytes<Type>(bytes)(constructor arguments for Type) Meant to resemble placement-new syntax with separation of allocator and constructor arguments

Definition at line 192 of file PackedArray.h.

{
   return [enlarged](auto &&...args) {
      return Ptr<Type>{
         safenew(PackedArrayArg, enlarged)
            Type{ std::forward<decltype(args)>(args)... },
         std::max(sizeof(Type), enlarged) // Deleter's constructor argument
      };
   };
}

AllocateCount()

template<typename Type >

auto PackedArray::AllocateCount

(

size_t

count

)

Allocate a Ptr<Type> holding count elements.

Usage: AllocateCount<Type>(count)(constructor arguments for Type) Meant to resemble placement-new syntax with separation of allocator and constructor arguments

If Traits<Type> defines a nonempty header, the result always holds at least one element

Definition at line 212 of file PackedArray.h.

{
   using traits_type = detail::ExtendedTraits<Type>;
   const auto bytes = traits_type::element_offset()
      + count * sizeof(typename traits_type::element_type);
   return AllocateBytes<Type>(bytes);
}

begin()

template<typename Type , template< typename > typename BaseDeleter>

auto PackedArray::begin ( const Ptr< Type, BaseDeleter > &  p )

inline

Enables range-for.
