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 ! ;)

Member Function Documentation
| 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.

| virtual BinaryDataSource<function>* RTT::internal::BinaryDataSource< function >::copy | ( | std::map< const base::DataSourceBase *, base::DataSourceBase * > & | alreadyCloned | ) | const [inline, virtual] |
Implements RTT::internal::DataSource< remove_cr< function::result_type >::type >.
Definition at line 739 of file DataSources.hpp.
| 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.
| virtual void RTT::internal::BinaryDataSource< function >::reset | ( | ) | [inline, virtual] |
Reset the data to initial values.
Reimplemented from RTT::base::DataSourceBase.
Definition at line 728 of file DataSources.hpp.
| 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.

| 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.
