|When copying an Orocos program, we want identical internal::DataSource's to be mapped to identical DataSources, in order for the program to work correctly. |

Evaluates a internal::DataSource<bool> in a command.
The result will be evaluated in a EvalCommandResult, so this Command returns always true : ie the evaluation itself always succeeds. An EvalCommand should never be dispatched, since the EvalCommandResult assumes the EvalCommand has been executed when evaluated.

This is different from the clone function, where we simply want a new Action that can replace the old one directly.
This function takes a map that maps the old internal::DataSource's onto their new replacements. This way, it is possible to check before cloning a internal::DataSource, whether it has already been copied, and if so, reuse the existing copy.
To keep old source working, the standard implementation of this function simply calls the clone function. If your ActionInterface uses a internal::DataSource, it is important that you reimplement this function correctly though.
Reimplemented from RTT::base::ActionInterface.
|bool RTT::ActionInterface::valid||(||)|| const
Inspect if this action was executed and valid.
