Member Function Documentation

template<typename T>

RTT::internal::DataSource< T >::BOOST_STATIC_ASSERT

(

!details::HasConst< T >::value

)

If you get a compile error here, it means T has const or reference qualifiers, which is not allowed for DataSource<T>

template<typename T>

virtual DataSource<T>* RTT::internal::DataSource< T >::clone

(

)

const [pure virtual]

Return a shallow clone of this DataSource. This method returns a duplicate of this instance which re-uses the DataSources this internal::DataSource holds reference to. The clone() function is thus a non-deep copy.

Implements RTT::base::DataSourceBase.
