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