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:
T Any type of data, except being a non-const reference.

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 >::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>
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 [inline, virtual]

Return the data as type T.

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

Definition at line 141 of file rtt/internal/DataSources.hpp.

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

Return the data as type T.

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

Definition at line 141 of file install/include/rtt/internal/DataSources.hpp.

template<typename T>
DataSource<T>::const_reference_t RTT::internal::ConstantDataSource< 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 151 of file rtt/internal/DataSources.hpp.

template<typename T>
DataSource<T>::const_reference_t RTT::internal::ConstantDataSource< 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 151 of file install/include/rtt/internal/DataSources.hpp.

template<typename T>
DataSource<T>::result_t RTT::internal::ConstantDataSource< 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 146 of file rtt/internal/DataSources.hpp.

template<typename T>
DataSource<T>::result_t RTT::internal::ConstantDataSource< 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 >.

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.
