Member Function Documentation

CommandInterface* RTT::CommandDataSourceBool::copy ( std::map< const DataSourceBase *, DataSourceBase * > &  alreadyCloned  )  const [inline, virtual]

When copying an Orocos program, we want identical 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 DataSource's onto their new replacements. This way, it is possible to check before cloning a 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 DataSource, it is important that you reimplement this function correctly though.

Reimplemented from RTT::ActionInterface.

References RTT::DataSource< T >::copy().

bool RTT::CommandDataSourceBool::execute (  )  [inline, virtual]

Execute the functionality of this action.

Returns:
true if the action was accepted, false otherwise

Implements RTT::ActionInterface.

Definition at line 95 of file CommandDataSource.hpp.

References RTT::DataSource< T >::value().

void RTT::CommandDataSourceBool::reset (  )  [inline, virtual]

Reset this action.

Must be used after execute() failed.

Reimplemented from RTT::ActionInterface.

Definition at line 98 of file CommandDataSource.hpp.

References RTT::DataSourceBase::reset().

virtual bool RTT::ActionInterface::valid (  )  const [virtual, inherited]

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::CommandComposite, RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, RTT::detail::DataSourceArgsCommand< CommandT, CommandF >, RTT::DispatchAction, RTT::DispatchInterface, and RTT::TryCommand.
