It provides a running process of desired activity returned by interface [IStandaloneActivityCreator](classsimulation__framework_1_1core_1_1IStandaloneActivityCreator.xhtml "This is the interface class for creating a standalone activity service. It defines how a customized a...") and keeps it communicating and being scheduled by simulation framework core process.

If you have implemented my\_activity\_creator.h of interface [IStandaloneActivityCreator](classsimulation__framework_1_1core_1_1IStandaloneActivityCreator.xhtml "This is the interface class for creating a standalone activity service. It defines how a customized a...") based on example in simfwk-core/service/standalone\_activity\_service/standalone\_activity\_creator/i\_standalone\_activity\_creator.h, then you can create an executable using this class, which runs your desired activity as service, keep talking and being scheduled by simfwk\_cli.

This example shows how to implement this process and join the simulation from standalone
