Detailed Description

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

A DataSource which holds a constant value and returns it in its get() method. It can not be changed after creation.

Parameters
TAny type of data, except being a non-const reference.

Definition at line 111 of file DataSources.hpp.

Member Typedef Documentation

template<typename T>
typedef boost::intrusive_ptr< ConstantDataSource<T> > RTT::internal::ConstantDataSource< T >::shared_ptr

Definition at line 126 of file DataSources.hpp.

Constructor & Destructor Documentation

template<typename T>
RTT::internal::ConstantDataSource< T >::~ConstantDataSource ( )

Use shared_ptr.

template<typename T>
RTT::internal::ConstantDataSource< T >::ConstantDataSource ( value)

Member Function Documentation

template<typename T>
virtual ConstantDataSource<T>* RTT::internal::ConstantDataSource< 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::DataSource< T >.

template<typename T>
virtual ConstantDataSource<T>* RTT::internal::ConstantDataSource< T >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > &  alreadyCloned) const
virtual
template<typename T>
DataSource<T>::result_t RTT::internal::ConstantDataSource< T >::get ( ) const
inlinevirtual

Return the data as type T.

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

Definition at line 130 of file DataSources.hpp.

template<typename T>
DataSource<T>::const_reference_t RTT::internal::ConstantDataSource< T >::rvalue ( ) const
inlinevirtual

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 140 of file DataSources.hpp.

template<typename T>
DataSource<T>::result_t RTT::internal::ConstantDataSource< T >::value ( ) const
inlinevirtual

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 135 of file DataSources.hpp.

Member Data Documentation

template<typename T>
boost::add_const<typename DataSource<T>::value_t>::type RTT::internal::ConstantDataSource< T >::mdata
private

Assure that mdata is const, such that T is forced to not be a non-const reference.

Definition at line 118 of file DataSources.hpp.
