Member Enumeration Documentation
enum RTT::DispatchInterface::Status [inherited] |
The status progressions of a Dispatchable Command.
The order of these enums is important and should not be altered.
- Enumerator:
Ready The command is not yet initialised.
Sent The command is ready for execution.
NotAccepted The command has been sent/dispatched to the CommandProcessor.
Accepted The command was not accepted by the CommandProcessor.
Executed The command was accepted by the CommandProcessor.
NotValid The command was executed by the CommandProcessor.
Valid The command's arguments were found to be invalid.
Done The command's arguments were valid.
Definition at line 65 of file DispatchInterface.hpp.
Member Function Documentation
| virtual bool RTT::DispatchInterface::accepted | ( | ) | const [pure virtual, inherited] |
Returns true if the command was accepted when sent to the CommandProcessor.
A Command is accepted when the CommandProcessor was running and its queue was not full.
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
| virtual DispatchInterface* RTT::DispatchInterface::copy | ( | std::map< const DataSourceBase *, DataSourceBase * > & | alreadyCloned | ) | const [inline, virtual, inherited] |
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.
Reimplemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
Definition at line 128 of file DispatchInterface.hpp.
| virtual bool RTT::DispatchInterface::dispatch | ( | ) | [pure virtual, inherited] |
Dispatch a command.
If it is not accepted, fail, if it is accepted, return true
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
| virtual bool RTT::ActionInterface::execute | ( | ) | [pure virtual, inherited] |
Execute the functionality of this action.
- Returns:
- true if the action was accepted, false otherwise
Implemented in RTT::AsynchCommandDecorator, RTT::CommandComposite, RTT::CommandCounter, RTT::CommandDataSource, RTT::CommandDataSourceBool, RTT::CommandDispatch, RTT::CommandExecFunction, RTT::CommandFunctor< F >, RTT::CommandFunctor< boost::function< bool(void) > >, RTT::CommandIllegal, RTT::CommandNOP, RTT::CommandString, RTT::Corba::CommandProxy, RTT::detail::DataSourceArgsCommand< CommandT, CommandF >, RTT::detail::DataSourceArgsEvent< SignatureT, FunctorT >, RTT::DispatchAction, RTT::detail::EventBase< Signature >, RTT::TryCommand, and RTT::EvalCommand.
| virtual bool RTT::DispatchInterface::executed | ( | ) | const [pure virtual, inherited] |
Returns true if the command was executed by the CommandProcessor.
When executed() is true, you can check if it was found valid().
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
| bool RTT::detail::RemoteCommandImpl< CommandT >::invoke | ( | ) | [inline] |
Call this operator if the RemoteCommand takes no arguments.
- Returns:
- true if ready and succesfully sent.
Definition at line 81 of file RemoteCommand.hpp.
References RTT::CommandC::execute().
| virtual bool RTT::DispatchInterface::ready | ( | ) | const [pure virtual, inherited] |
The command's effect is done.
Returns true if the command is ready for dispatch. If ready() returns true, dispatch() can be safely called, otherwise, dispatch() will fail.
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
| virtual bool RTT::DispatchInterface::sent | ( | ) | const [pure virtual, inherited] |
Returns true if the command was sent to the CommandProcessor.
You can use this flag to check whether execute() was invoked.
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
| virtual bool RTT::DispatchInterface::valid | ( | ) | const [pure virtual, inherited] |
Returns true if the command was valid, i.e.
the command itself was executed and returned true.
Reimplemented from RTT::ActionInterface.
Implemented in RTT::CommandDispatch, RTT::CommandExecFunction, RTT::Corba::CommandProxy, and RTT::detail::DataSourceArgsCommand< CommandT, CommandF >.
