As default type, DDS type will be applied. TopicId is globally unique and represents one single [Topic](classsimulation__framework_1_1core_1_1Topic.xhtml "This is the concrete Topic class that can be used for creation of a communication channel with given ..."). Different Topics can hold same underlying message type but they are different topics for communication C[simulation\_framework::core::kpi::IKpi< T >](classsimulation__framework_1_1core_1_1kpi_1_1IKpi.xhtml)Class [IKpi](classsimulation__framework_1_1core_1_1kpi_1_1IKpi.xhtml "class IKpi") ▼C[simulation\_framework::core::kpi::IKpiMessageConverter](classsimulation__framework_1_1core_1_1kpi_1_1IKpiMessageConverter.xhtml)Class [IKpiMessageConverter](classsimulation__framework_1_1core_1_1kpi_1_1IKpiMessageConverter.xhtml "class IKpiMessageConverter") C[simulation\_framework::core::kpi::KpiMessageConverter](classsimulation__framework_1_1core_1_1kpi_1_1KpiMessageConverter.xhtml)Class [KpiMessageConverter](classsimulation__framework_1_1core_1_1kpi_1_1KpiMessageConverter.xhtml "class KpiMessageConverter") C[simulation\_framework::core::kpi::KpiContent](structsimulation__framework_1_1core_1_1kpi_1_1KpiContent.xhtml)Struct [KpiContent](structsimulation__framework_1_1core_1_1kpi_1_1KpiContent.xhtml "struct KpiContent") ▼C[simulation\_framework::core::lifecycle::IActivity](classsimulation__framework_1_1core_1_1lifecycle_1_1IActivity.xhtml)Class [IActivity](classsimulation__framework_1_1core_1_1lifecycle_1_1IActivity.xhtml "class IActivity") C[simulation\_framework::core::lifecycle::BaseActivity](classsimulation__framework_1_1core_1_1lifecycle_1_1BaseActivity.xhtml)This is the basic implementation of [IActivity](classsimulation__framework_1_1core_1_1lifecycle_1_1IActivity.xhtml "class IActivity") interface and used as base class of all customized activities.
