// 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.
