Class template buffer_allocator

boost::compute::buffer_allocator — The buffer_allocator class allocates memory with buffer objects.

Synopsis

// In header: <boost/compute/allocator/buffer_allocator.hpp>

template<typename T> 
class buffer_allocator {
public:
  // types
  typedef T              value_type;     
  typedef unspecified    pointer;        
  typedef unspecified    const_pointer;  
  typedef std::size_t    size_type;      
  typedef std::ptrdiff_t difference_type;

  // public member functions
  explicit buffer_allocator(const context &);
  buffer_allocator(const buffer_allocator< T > &);
  buffer_allocator< T > & operator=(const buffer_allocator< T > &);
  buffer_allocator(buffer_allocator< T > &&) noexcept;
  buffer_allocator< T > & operator=(buffer_allocator< T > &&) noexcept;
  ~buffer_allocator();
  pointer allocate(size_type);
  void deallocate(pointer, size_type);
  size_type max_size() const;
  context get_context() const;

  // protected member functions
