Index type based in boost::intrusive::set. Just derives from boost::intrusive::set and defines the interface needed by managed memory segments

iunordered_set_index public construct/copy/destruct

  1. iunordered_set_index(segment_manager_base * mngr);

    Constructor. Takes a pointer to the segment manager. Can throw

  2. ~iunordered_set_index();

iunordered_set_index public member functions

  1. void reserve(size_type new_n);

    This reserves memory to optimize the insertion of n elements in the index

  2. void shrink_to_fit();

    This tries to free unused memory previously allocated.

  3. iterator find(const intrusive_compare_key_type & key);
  4. const_iterator find(const intrusive_compare_key_type & key) const;
  5. std::pair< iterator, bool > 
    insert_check(const intrusive_compare_key_type & key, 
                 insert_commit_data & commit_data);
  6. iterator insert_commit(value_type & val, insert_commit_data & commit_data);
