NAME¶

std::experimental::pmr::monotonic_buffer_resource - std::experimental::pmr::monotonic_buffer_resource

Synopsis¶

Defined in header <experimental/memory_resource>
class monotonic_buffer_resource : public memory_resource; (library fundamentals TS)

The class std::experimental::pmr::monotonic_buffer_resource is an special-purpose
memory resource class that releases the allocated memory only when the resource is
destroyed. It is intended for very fast memory allocations in situations where
memory is used to build up a few objects and then is released all at once.

monotonic_buffer_resource can be constructed with an initial buffer. If there is no
initial buffer, or if the buffer is exhausted, additional buffers are obtained from
an upstream memory resource supplied at construction. The size of buffers obtained
follows a geometric progression.

monotonic_buffer_resource is not thread-safe.

Member functions¶

constructor Constructs a monotonic_buffer_resource
(public member function)
destructor Destroys a monotonic_buffer_resource, releasing all allocated
[virtual] memory
(virtual public member function)
operator= Copy assignment operator is deleted. monotonic_buffer_resource is
[deleted] not copy assignable
(public member function)

Public member functions¶

release Release all allocated memory
(public member function)
upstream_resource Returns a pointer to the upstream memory resource
