raisim::AlignedAllocator

class · #include <raisim/helper.hpp>

template <typename T, std::size_t RSALOCATOR_ALIGNMENT>
class AlignedAllocator

Standard allocator that returns memory aligned to RSALOCATOR_ALIGNMENT bytes (e.g. for vectors of fixed-size Eigen-backed types).

Nested classes

• struct rebind — Allocator for another element type with the same alignment.

Public types

value_type

using value_type = T

size_type

using size_type = std::size_t

difference_type

using difference_type = std::ptrdiff_t

propagate_on_container_move_assignment

using propagate_on_container_move_assignment = std::true_type

is_always_equal

using is_always_equal = std::true_type

Constructors & destructor

AlignedAllocator

AlignedAllocator() noexcept = default

template <typename U>
AlignedAllocator(const AlignedAllocator<U, RSALOCATOR_ALIGNMENT> &) noexcept

Converting copy (stateless allocator).

Public member functions

max_size

size_type max_size() const noexcept

Returns the largest element count that can be requested

allocate

T *allocate(size_type n)

Parameters

Parameter	Description
n (in)	number of elements

Returns aligned uninitialized storage, or nullptr for n == 0. Throws std::bad_array_new_length if n > max_size()

deallocate

void deallocate(T *p, size_type) noexcept

Release storage obtained from allocate().

Parameters

Parameter	Description
p (in)	pointer returned by allocate()

operator==

bool operator==(const AlignedAllocator &) const noexcept

Returns true; all instances are interchangeable

operator!=

bool operator!=(const AlignedAllocator &) const noexcept

Returns false; all instances are interchangeable
