Detailed Description

template<typename function>
class RTT::internal::BinaryDataSource< function >

A generic binary composite DataSource. It takes a function object which is a model of the STL Adaptable Binary Function concept, and two DataSource's with result types matching the argument types of the given function. Its get() method then applies the function to the results of the get() methods of the two DataSource's given.

The parser system uses a hell of a lot of these for evaluating expressions, comparisons etc. I must say I think this is pretty cool ;) C++ rocks ! ;)

template<typename function>
typedef boost::intrusive_ptr<BinaryDataSource<function> > RTT::internal::BinaryDataSource< function >::shared_ptr

Use this type to store a pointer to a DataSourceBase.

Reimplemented from RTT::internal::DataSource< remove_cr< function::result_type >::type >.

template<typename function>
typedef remove_cr<typename function::result_type>::type RTT::internal::BinaryDataSource< function >::value_t [private]

The bare type of T is extracted into value_t.

Constructor & Destructor Documentation

template<typename function>
RTT::internal::BinaryDataSource< function >::BinaryDataSource ( typename DataSource< first_arg_t >::shared_ptr  a,
typename DataSource< second_arg_t >::shared_ptr  b,
function  f 
) [inline]

Create a DataSource which returns the return value of a function f which is given argument a and b.

Definition at line 704 of file DataSources.hpp.


Member Function Documentation

template<typename function>
virtual BinaryDataSource<function>* RTT::internal::BinaryDataSource< function >::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::DataSource< remove_cr< function::result_type >::type >.

Definition at line 734 of file DataSources.hpp.

template<typename function>
virtual BinaryDataSource<function>* RTT::internal::BinaryDataSource< function >::copy ( std::map< const base::DataSourceBase *, base::DataSourceBase * > &  alreadyCloned) const [inline, virtual]
template<typename function>
virtual value_t RTT::internal::BinaryDataSource< function >::get ( ) const [inline, virtual]

Return the data as type T.

Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.

Definition at line 711 of file DataSources.hpp.

template<typename function>
virtual void RTT::internal::BinaryDataSource< function >::reset ( void  ) [inline, virtual]

Reset the data to initial values.

Reimplemented from RTT::base::DataSourceBase.

Definition at line 728 of file DataSources.hpp.

template<typename function>
DataSource<value_t>::const_reference_t RTT::internal::BinaryDataSource< function >::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< remove_cr< function::result_type >::type >.

Definition at line 723 of file DataSources.hpp.

template<typename function>
virtual value_t RTT::internal::BinaryDataSource< function >::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< remove_cr< function::result_type >::type >.
