Member Typedef Documentation

template<typename T>

Constructor & Destructor Documentation

template<typename T>

RTT::internal::ConstReferenceDataSource< T >::~ConstReferenceDataSource ( )

Use shared_ptr.

template<typename T>

RTT::internal::ConstReferenceDataSource< T >::ConstReferenceDataSource ( typename DataSource< T >::const_reference_t ref )

Member Function Documentation

template<typename T>

virtual ConstReferenceDataSource<T>* RTT::internal::ConstReferenceDataSource< T >::clone ( ) const

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::internal::DataSource< T >.

template<typename T>

virtual ConstReferenceDataSource<T>* RTT::internal::ConstReferenceDataSource< T >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > & alreadyCloned ) const

virtual

Implements RTT::internal::DataSource< T >.

template<typename T>

DataSource<T>::result_t RTT::internal::ConstReferenceDataSource< T >::get ( ) const

inlinevirtual

Return the data as type T.

Implements RTT::internal::DataSource< T >.

Definition at line 171 of file DataSources.hpp.

template<typename T>

DataSource<T>::const_reference_t RTT::internal::ConstReferenceDataSource< T >::rvalue ( ) const

inlinevirtual

Get a const reference to the value of this DataSource. You must call evaluate() prior to calling this function in order to get the most recent value of this attribute.

Note: Getting a reference to an internal data structure is not thread-safe.

Implements RTT::internal::DataSource< T >.

Definition at line 181 of file DataSources.hpp.

template<typename T>

DataSource<T>::result_t RTT::internal::ConstReferenceDataSource< T >::value ( ) const

inlinevirtual

Return the result of the last evaluate() function. You must call evaluate() prior to calling this function in order to get the most recent value of this attribute.

Implements RTT::internal::DataSource< T >.
