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 member functions

  1. (segment_manager_base * segment_mngr);

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

  2.  ();

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

  3.  ();

    This tries to free previously allocate unused memory.

  4.  
    ( key, );
  5.  ( k,  context, 
                            index_data, );
