 <a id="details" name="details"></a>## Detailed Description

This is the interface class for creating a standalone activity service. It defines how a customized activity needs to be instantiated through or not through StandaloneInitData.

You have already the example how you create an activity "MyActivity" in [core/lifecycle/activity/base\_activity.h](base__activity_8h_source.xhtml)

This example shows how to implement the [IStandaloneActivityCreator](classsimulation__framework_1_1standalone__activity__service_1_1IStandaloneActivityCreator.xhtml "This is the interface class for creating a standalone activity service. It defines how a customized a...") interface based on "MyActivity"

using TopicToBePublished = Topic&lt;MsgToBePublished&gt;;

using TopicSubscribingOn = Topic&lt;MsgSubscribingOn&gt;;

 

class MyActivityCreator : public IStandaloneActivityCreator

{

 public:

 MyActivityCreator(const std::string&amp; name) : standalone_activity_name_(name) {}

 IActivityPtr [Create](classsimulation__framework_1_1standalone__activity__service_1_1IStandaloneActivityCreator.xhtml#aba16240cc33bb6fa5a9eaef04ef78d9d)(const core::scheduling::StandaloneInitData&amp; standalone_init_data) override

 {

 TopicPtr topic_going_to_publish = std::make_shared&lt;TopicToBePublished&gt;("TopicToBePublished");

 TopicPtr topic_want_to_receive = std::make_shared&lt;TopicSubscribingOn&gt;("TopicSubscribingOn");

 

 return std::make_unique&lt;MyActivity&gt;(

 standalone_activity_name_, Topics{topic_going_to_publish, topic_want_to_receive}, MyLogic{});

 }

 std::string [GetName](classsimulation__framework_1_1standalone__activity__service_1_1IStandaloneActivityCreator.xhtml#a1534824e56569105e521cbb28d62363c)() override { return standalone_activity_name_; }
