Constructors

allocator_set(const Allocator& alloc=Allocator(), const TempAllocator& temp_alloc=TempAllocator())

Constructs an allocator_set with an allocator for result data and a second allocator for temporary allocations.

allocator_set(const allocator_set& other)

Copy constructor.

allocator_set(allocator_set&& other)

Move constructor.

Accessors

Allocator get_allocator() const;

Returns an allocator object for result data

TempAllocator get_temp_allocator() const;

Returns an allocator object for for temporary allocations

Helper functions

template <typename Allocator,class TempAllocator>
allocator_set<Allocator,TempAllocator> combine_allocators(
    const Allocator& alloc, const TempAllocator& temp_alloc);

Combines an allocator for result data and an allocator for temporary allocations into an allocator_set object, deducing the allocator types from the types of the arguments.

allocator_set<std::allocator<char>,std::allocator<char>> combine_allocators()

Creates an allocator_set<std::allocator<char>,std::allocator<char>> object with default allocators for result data and temporary allocations.

template <typename Allocator>
allocator_set<Allocator,std::allocator<char>> combine_allocators(
    const Allocator& alloc);

Creates an allocator_set with the provided allocator for result data and defaulting to a std::allocator<char> for temporary allocations.

template <typename TempAllocator>
allocator_set<std::allocator<char>,TempAllocator> temp_allocator_only(const TempAllocator& temp_alloc)

Creates a allocator_set object, defaulting the result allocator type to std::allocator<char> and deducing the temp allocator type from the type of the temp_alloc argument.
