Class template flat_map_index



// In header: <boost/interprocess/indexes/flat_map_index.hpp>

template<typename MapConfig> 
class flat_map_index : public flat_map_index_aux::index_t< MapConfig > {
  // construct/copy/destruct
  flat_map_index(segment_manager_base *);

  // public member functions
  void reserve(typename segment_manager_base::size_type);
  void shrink_to_fit();


Index type based in flat_map. Just derives from flat_map and defines the interface needed by managed memory segments.

flat_map_index public construct/copy/destruct

  1. flat_map_index(segment_manager_base * segment_mngr);
    Constructor. Takes a pointer to the segment manager. Can throw.

flat_map_index public member functions

  1. void reserve(typename segment_manager_base::size_type n);
    This reserves memory to optimize the insertion of n elements in the index.
  2. void shrink_to_fit();
    This frees all unnecessary memory.
