| // 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. |
