NAME

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

Synopsis


monotonic_buffer_resource(); (1) (library fundamentals TS)
explicit monotonic_buffer_resource( memory_resource* (2) (library fundamentals TS)
upstream );
explicit monotonic_buffer_resource( std::size_t (3) (library fundamentals TS)
initial_size );
monotonic_buffer_resource( std::size_t initial_size,
memory_resource* upstream (4) (library fundamentals TS)
);
monotonic_buffer_resource( void* buffer, std::size_t (5) (library fundamentals TS)
buffer_size );
monotonic_buffer_resource( void* buffer, std::size_t
buffer_size, (6) (library fundamentals TS)
memory_resource* upstream
);
monotonic_buffer_resource( const (7) (library fundamentals TS)
monotonic_buffer_resource& ) = delete;


Constructs a monotonic_buffer_resource. The constructors not taking an upstream
memory resource pointer uses the return value of
std::experimental::pmr::get_default_resource() as the upstream memory resource.


1,2) Sets the current buffer to null and the next buffer size to an
implementation-defined size.
3,4) Sets the current buffer to null and the next buffer size to a size no smaller
than initial_size.
5,6) Sets the current buffer to buffer and the next buffer size to buffer_size (but
not less than 1). Then increase the next buffer size by an implementation-defined
growth factor (which does not have to be integral).
7) Copy constructor is deleted.

Parameters


upstream - the upstream memory resource to use; must point to a valid memory
resource
initial_size - the minimum size of the first buffer to allocate; must be greater
than zero
buffer - the initial buffer to use
buffer_size - the size of the initial buffer; cannot be greater than the number of
bytes in buffer
