|ConditionExpire (ticks t)|
|Create a Condition that evaluates to false when t is reached. |
|virtual bool||evaluate ()|
|Evaluate the Condition and return the outcome. |

|Some conditions need to be reset at some points. |
|virtual ConditionInterface *||clone () const|
|The Clone Software Pattern. |
|virtual ConditionInterface *||copy (std::map< const DataSourceBase *, DataSourceBase * > &alreadyCloned) const|
|When copying an Orocos program, we want identical DataSource's to be mapped to identical DataSources, in order for the program to work correctly. |
A conditional that evaluates true until a certain time has elapsed since construction or the last reset().
|virtual ConditionInterface* RTT::ConditionInterface::copy||(||std::map< const DataSourceBase *, DataSourceBase * > &||alreadyCloned||)|| const
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 Command 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 ConditionInterface uses a DataSource, it is important that you reimplement this function correctly though.
Reimplemented in RTT::ConditionExecFunction, RTT::detail::ConditionFunctor< SignatureT, FunctorT >, RTT::ConditionBoolDataSource, RTT::ConditionBinaryCompositeAND, RTT::ConditionDSDuration, RTT::ConditionInvert, RTT::TryCommandResult, and RTT::EvalCommandResult.
|virtual bool RTT::ConditionExpire::evaluate||(||)||
|virtual void RTT::ConditionExpire::reset||(||)||
Some conditions need to be reset at some points.
E.g. a ConditionDuration counts the time since the first time a Command was executed, and if this time exceeds a certain preset time, returns true. Therefore, it needs to be reset, i.e. it needs to start counting, when the command is first executed.. ConditionOnce has a similar need. This function is called at such times.
Reimplemented from RTT::ConditionInterface.
