Member Function Documentation
| virtual bool execute | ( | ) | [pure virtual] |
Execute as much actions until the program needs to wait on a condition to become true.
When paused, only execute one action.
- Returns:
- false if a program error occured.
Implemented in FunctionGraph.
Referenced by StateMachine::pause(), and ProgramProcessor::step().
| virtual ProgramInterface* copy | ( | std::map< const DataSourceBase *, DataSourceBase * > & | replacementdss | ) | const [pure virtual] |
Clone this Program.
This will produce a completely new instance, that has nothing in common with this one. It takes care to properly map identical DataSources to identical DataSources.
- Parameters:
-
alreadyMappedData A map of some DataSources used in this program to new DataSources that should replace them in the new Program. This is provided, because in some cases the outside world also keeps references to datasources used somewhere in this programgraph. It is then important that when this Program is copied, the outside world has a way to get a reference to the corresponding datasources in the new program. We do this by allowing it to map some datasources itself, and simply provide us a list of its mappings.
Implemented in FunctionGraph.
