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.

template<typename T>

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

pure virtual

Create a deep copy of this internal::DataSource, unless it is already cloned.

Places the association (parent, clone) in alreadyCloned. If the internal::DataSource is non-copyable (for example it represents the Property of a Task ), this may be returned.

Implements RTT::base::DataSourceBase.

template<typename T >

bool RTT::internal::DataSource< T >::evaluate ( ) const

virtual

Force an evaluation of the DataSourceBase.

Returns: true on successful evaluation.

Implements RTT::base::DataSourceBase.

template<typename T>

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

pure virtual

Return the data as type T.

DataSourceBase::shared_ptr RTT::DataSourceBase::getMember ( const std::string & member_name )

virtualinherited

Get a (const) reference data source to a member of the structure of this data source.

You must call getMember() in turn on the returned member to access sub-members.

Parameters

member_name The name of the member to get access to.

Returns: null if the member does not exist, this if member_name.empty(), and a reference data source to the member otherwise.

DataSourceBase::shared_ptr RTT::DataSourceBase::getMember	(	DataSourceBase::shared_ptr	member_id,
		DataSourceBase::shared_ptr	offset
	)

virtualinherited

Same as above, but with run-time lookup of the member to use.

Also takes an optional offset argument which can be used to offset the member in memory. This is necessary when using sequences of sequences. DataSources which are a sequence/offset member themselves must override this function to let the returned member take the offset into account.

os::AtomicInt RTT::base::DataSourceBase::refcount

mutableprotectedinherited

We keep the refcount ourselves.

We aren't using boost::shared_ptr, because boost::intrusive_ptr is better, exactly because it can be used with refcounts that are stored in the class itself. Advantages are that the shared_ptr's for derived classes use the same refcount, which is of course very much desired, and that refcounting happens in an efficient way, which is also nice :)
