template<typename T >

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

Use shared_ptr.

Definition at line 129 of file DataSources.inl.

template<typename T >

RTT::internal::ArrayDataSource< T >::ArrayDataSource ( std::size_t size = 0 )

Create and allocate an Array of a fixed size.

In case you create an empty/default ArrayDataSource, you can assign it an array size later-on with newArray( size )

Definition at line 132 of file DataSources.inl.

template<typename T >

RTT::internal::ArrayDataSource< T >::ArrayDataSource ( T const & odata )

Creates an ArrayDataSource and initializes the array with the contents of another carray.

A deep copy is made from odata.

template<typename T>

RTT::internal::DataSource< T >::BOOST_STATIC_ASSERT ( !details::HasConst< T >::value )

inherited

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 >

ArrayDataSource< T > * RTT::internal::ArrayDataSource< 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 >.

template<typename T >

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

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.

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.

	)

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.

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 :)
