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.

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 in RTT::scripting::CallFunction, RTT::scripting::EvalCommand, RTT::scripting::CommandComposite, RTT::scripting::CommandDataSourceBool, RTT::internal::AssignCommand< T, S >, RTT::scripting::TryCommand, RTT::scripting::CommandBinary, and RTT::scripting::CommandDataSource.

virtual bool RTT::scripting::CommandFunction::execute ( )
inlinevirtual

Execute the functionality of this action.

Returns
true if the action was accepted, false otherwise

Implements RTT::base::ActionInterface.

virtual void RTT::scripting::CommandFunction::readArguments ( )
inlinevirtual

This is invoked some time before execute() at a time when the action may read its function arguments.

Implements RTT::base::ActionInterface.

Definition at line 73 of file CommandFunctors.hpp.

void ActionInterface::reset ( )
virtualinherited
bool ActionInterface::valid ( ) const
virtualinherited

Inspect if this action was executed and valid.

This method may not be called before execute(). The default implementation returns always true, i.e. after execute(), it was executed. Override this method if it has more complex state semantics.

Reimplemented in RTT::scripting::CallFunction, RTT::scripting::CommandComposite, RTT::scripting::TryCommand, and RTT::scripting::CommandBinary.
