Detailed Description

template<class List>
struct RTT::internal::create_sequence< List >

This class can create three kinds of Boost Fusion Sequences.

sources() creates a fusion sequence of (Assignable)DataSource<T>::shared_ptr from an mpl sequence and a std::vector<DataSourceBase*>. Both must have same length. The mpl sequence is typically obtained from the function_types parameter_types traits class.

assignable() creates a fusion sequence of AssignableDataSource<T>::shared_ptr from an mpl sequence and a std::vector<DataSourceBase*>. Both must have same length. The mpl sequence is typically obtained from the function_types parameter_types traits class. If the mpl sequence elements contain const qualifiers, these are removed, so T is always a value type.

data() creates a fusion sequence of T,U,V,... from the fusion sequence returned by operator(). It contains the values of the data sources obtained by calling get().

copy() creates a fusion sequence of DataSource<T>::shared_ptr from an mpl sequence and a sequence returned by operator() to do the scripting copy/clone semantics on each element of the sequence.

This is a typical head-tail recursive implementation where operator() calls itself, but in another type specialisation.

template<class List, int size>

static atype RTT::internal::create_sequence_impl< List, size >::assignable	(	std::vector< base::DataSourceBase::shared_ptr >::const_iterator	args,
		int	argnbr = `1`
	)		`[inline, static, inherited]`

Converts a std::vector of DataSourceBase types into a boost::fusion Sequence of AssignableDataSources of the types given in List.

Will throw if an element of the vector could not be dynamic casted to the respective element type of List.

Parameters:

Copies a sequence of DataSource<T>::shared_ptr according to the copy/clone semantics of data sources.

Parameters:

seq	A Fusion Sequence of DataSource<T>::shared_ptr
