std::pmr::monotonic_buffer_resource: std::pmr::monotonic_buffer_resource

NAME

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

Synopsis

Defined in header <memory_resource>
class monotonic_buffer_resource : public std::pmr::memory_resource; (since C++17)

The class std::pmr::monotonic_buffer_resource is a 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.
