Description

A basic user memory named object creation class. Inherits all basic functionality from basic_managed_memory_impl<CharType, AllocationAlgorithm, IndexType>*<zwj></zwj>/

basic_managed_external_buffer public construct/copy/destruct

  1. ();

    Default constructor. Does nothing. Useful in combination with move semantics

  2. (create_only_t,  addr,  size);
    Creates and places the segment manager. This can throw.
  3. (open_only_t,  addr,  size);
    Creates and places the segment manager. This can throw.
  4. (basic_managed_external_buffer && moved);
    Moves the ownership of "moved"'s managed memory to *this. Does not throw.
  5. basic_managed_external_buffer & 
    (basic_managed_external_buffer && moved);
    Moves the ownership of "moved"'s managed memory to *this. Does not throw.

basic_managed_external_buffer public member functions

  1.  ( extra_bytes);
  2.  (basic_managed_external_buffer & other);
