- // Summary:
- // A semantic action policy that insert data into an associative
- // container using a const reference to a key.
- // (This doc uses convention available in actors.hpp)
- //
- // Actions (what it does):
- // ref.insert( T::value_type(key_ref,value) );
- // ref.insert( T::value_type(key_ref, T::mapped_type(first,last)));;
- // ref.insert( T::value_type(key_ref,value_ref) );
- //
- // Policy name:
- // insert_at_action
- //
- // Policy holder, corresponding helper method:
- // ref_const_ref_value_actor, insert_at_a( ref, key_ref );
- // ref_const_ref_const_ref_actor, insert_a( ref, key_ref, value_ref );
- //
- // () operators: both
- //
- // See also ref_const_ref_value_actor and ref_const_ref_const_ref_actor
- // for more details.
