Detailed Description

template<typename T>
class RTT::internal::ArrayPartDataSource< T >

A DataSource which is used to manipulate a reference to a part of a data source holding a C-style array of elements.

This data source only works on a fixed reference in memory of a given array. In case the array's place in memory varies, you need the OffsetPartDataSource, which can access an element at any offset from a given memory location.

Parameters:

T	The data type of an element.

Member Typedef Documentation

template<typename T>

typedef boost::intrusive_ptr<ArrayPartDataSource<T> > RTT::internal::ArrayPartDataSource< T >::shared_ptr

Use this type to store a pointer to an AssignableDataSource.

Reimplemented from RTT::internal::AssignableDataSource< T >.

Definition at line 75 of file ArrayPartDataSource.hpp.

Constructor & Destructor Documentation

template<typename T>

RTT::internal::ArrayPartDataSource< T >::~ArrayPartDataSource ( ) [inline]

Definition at line 73 of file ArrayPartDataSource.hpp.

template<typename T>

RTT::internal::ArrayPartDataSource< T >::ArrayPartDataSource	(	typename AssignableDataSource< T >::reference_t	ref,
		DataSource< unsigned int >::shared_ptr	index,
		base::DataSourceBase::shared_ptr	parent,
		unsigned int	max
	)		`[inline]`

The part is constructed from a reference to an existing array of elements and an index for accessing the n'th element.

Parameters:

ref	Reference to the first element of the array
index	Datasource pointing to the index for use in operator[]
parent	Parent data source for sending updated() messages. May be null.

Member Function Documentation

template<typename T>

virtual ArrayPartDataSource<T>* RTT::internal::ArrayPartDataSource< T >::clone ( ) const [inline, 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 >.

Definition at line 136 of file ArrayPartDataSource.hpp.

template<typename T>

virtual ArrayPartDataSource<T>* RTT::internal::ArrayPartDataSource< T >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > & replace ) const [inline, virtual]

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

Definition at line 140 of file ArrayPartDataSource.hpp.

template<typename T>

DataSource<T>::result_t RTT::internal::ArrayPartDataSource< T >::get ( ) const [inline, virtual]

Return the data as type T.

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

Definition at line 91 of file ArrayPartDataSource.hpp.

template<typename T>

AssignableDataSource<T>::const_reference_t RTT::internal::ArrayPartDataSource< 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 124 of file ArrayPartDataSource.hpp.

template<typename T>

void RTT::internal::ArrayPartDataSource< T >::set ( typename AssignableDataSource< T >::param_t t ) [inline]

Definition at line 107 of file ArrayPartDataSource.hpp.

template<typename T>

AssignableDataSource<T>::reference_t RTT::internal::ArrayPartDataSource< 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 116 of file ArrayPartDataSource.hpp.

template<typename T>

void RTT::internal::ArrayPartDataSource< T >::updated ( ) [inline, virtual]

In case the internal::DataSource returns a 'reference' type, call this method to notify it that the data was updated in the course of an invocation of get().

Reimplemented from RTT::base::DataSourceBase.

Definition at line 132 of file ArrayPartDataSource.hpp.

template<typename T>

DataSource<T>::result_t RTT::internal::ArrayPartDataSource< 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 >.

Definition at line 99 of file ArrayPartDataSource.hpp.
