// 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
