Class template map_index

boost::interprocess::map_index

Synopsis

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

template<typename MapConfig> 
class map_index : public boost::interprocess_container::map<MapConfig> {
public:
  // construct/copy/destruct
  map_index(segment_manager_base *);

  // public member functions
  void reserve(std::size_t) ;
  void shrink_to_fit() ;
};

Description

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

map_index public construct/copy/destruct

  1. map_index(segment_manager_base * segment_mngr);

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

map_index public member functions

  1. void reserve(std::size_t) ;

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

  2. void shrink_to_fit() ;

    This tries to free previously allocate unused memory.
