20 | // Summary: | |
21 | // A semantic action policy that insert data into an associative | |
22 | // container using a const reference to a key. | |
23 | // (This doc uses convention available in actors.hpp) | |
24 | // | |
25 | // Actions (what it does): | |
26 | // ref.insert( T::value_type(key_ref,value) ); | |
27 | // ref.insert( T::value_type(key_ref, T::mapped_type(first,last)));; | |
28 | // ref.insert( T::value_type(key_ref,value_ref) ); | |
29 | // | |
30 | // Policy name: | |
31 | // insert_at_action | |
32 | // | |
33 | // Policy holder, corresponding helper method: | |
34 | // ref_const_ref_value_actor, insert_at_a( ref, key_ref ); | |
35 | // ref_const_ref_const_ref_actor, insert_a( ref, key_ref, value_ref ); | |
36 | // | |
37 | // () operators: both | |
38 | // | |
39 | // See also ref_const_ref_value_actor and ref_const_ref_const_ref_actor | |
40 | // for more details. | |
