- Parameters:
-
T The result data type of get().

Member Typedef Documentation
| typedef boost::intrusive_ptr<ReferenceDataSource<T> > RTT::internal::ReferenceDataSource< T >::shared_ptr |
Use this type to store a pointer to an AssignableDataSource.
Reimplemented from RTT::internal::AssignableDataSource< T >.
Definition at line 221 of file DataSources.hpp.
Constructor & Destructor Documentation
| RTT::internal::ReferenceDataSource< T >::~ReferenceDataSource | ( | ) |
Use shared_ptr.

Member Function Documentation
| virtual ReferenceDataSource<T>* RTT::internal::ReferenceDataSource< 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::AssignableDataSource< T >.
| virtual ReferenceDataSource<T>* RTT::internal::ReferenceDataSource< T >::copy | ( | std::map< const base::DataSourceBase *, base::DataSourceBase * > & | alreadyCloned | ) | const [virtual] |
Implements RTT::internal::AssignableDataSource< T >.
| DataSource<T>::result_t RTT::internal::ReferenceDataSource< T >::get | ( | ) | const [inline, virtual] |
Return the data as type T.
Implements RTT::internal::DataSource< T >.
Definition at line 241 of file DataSources.hpp.
| AssignableDataSource<T>::const_reference_t RTT::internal::ReferenceDataSource< T >::rvalue | ( | ) | const [inline, virtual] |
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 258 of file DataSources.hpp.
| void RTT::internal::ReferenceDataSource< T >::set | ( | typename AssignableDataSource< T >::param_t | t | ) |
| AssignableDataSource<T>::reference_t RTT::internal::ReferenceDataSource< T >::set | ( | ) | [inline, virtual] |
Get a reference to the value of this DataSource. Getting a reference to an internal data structure is not thread-safe.
Implements RTT::internal::AssignableDataSource< T >.
Definition at line 253 of file DataSources.hpp.
| void RTT::internal::ReferenceDataSource< T >::setReference | ( | void * | ref | ) | [inline, virtual] |
Sets the reference to a given pointer. The pointer must have the same type as the data referenced. No type checking is done, so make sure you get this right.
Implements RTT::internal::Reference.
Definition at line 225 of file DataSources.hpp.
| bool RTT::internal::ReferenceDataSource< T >::setReference | ( | base::DataSourceBase::shared_ptr | dsb | ) | [inline, virtual] |
Sets the reference to the data contained in the data source.
- Parameters:
-
dsb Must be an assignable data source of the same type of the data. The shared pointer is not necessarily stored, so keep track of the lifetime of dsb, that it lives longer than this object.
- Returns:
- false if setting failed. More precisely this might fail if dynamic_cast'ing the argument to the Reference DataSource fails.
- Note:
- This method will also call evaluate on the dsb to assure the correct value is used.
Implements RTT::internal::Reference.
Definition at line 229 of file DataSources.hpp.
| DataSource<T>::result_t RTT::internal::ReferenceDataSource< T >::value | ( | ) | const [inline, virtual] |
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 >.
