Detailed Description

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

A simple, yet very useful DataSource, which keeps a value, and returns it in its get() method. This is an AssignableDataSource, which thus can be changed.

Parameters

T	The result data type of get().

Member Function Documentation

template<typename T>

virtual ValueDataSource<T>* RTT::internal::ValueDataSource< 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>

virtual ValueDataSource<T>* RTT::internal::ValueDataSource< T >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > & replace ) const

virtual

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

template<typename T>

DataSource<T>::result_t RTT::internal::ValueDataSource< T >::get ( ) const

inlinevirtual

Return the data as type T.

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

Definition at line 78 of file DataSources.hpp.

template<typename T>

AssignableDataSource<T>::const_reference_t RTT::internal::ValueDataSource< 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 95 of file DataSources.hpp.

template<>

void RTT::internal::ValueDataSource< std::string >::set ( AssignableDataSource< std::string >::param_t t )

Specialisation for std::string to keep capacity when set( ... ) is called.

Definition at line 48 of file DataSources.cpp.

template<typename T>

void RTT::internal::ValueDataSource< T >::set ( typename AssignableDataSource< T >::param_t t )

template<typename T>

AssignableDataSource<T>::reference_t RTT::internal::ValueDataSource< T >::set ( )

inlinevirtual

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 90 of file DataSources.hpp.

template<typename T>

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