bool RTT::ConditionOnce::evaluate ( ) [virtual]

Evaluate the Condition and return the outcome.

Returns:
true if the condition is satisfied, false otherwise.

Implements RTT::scripting::ConditionInterface.

Definition at line 52 of file ConditionOnce.cpp.

void RTT::ConditionOnce::reset ( void  ) [virtual]

Some conditions need to be reset at some points. E.g. a scripting::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.. scripting::ConditionOnce has a similar need. This function is called at such times.

Reimplemented from RTT::scripting::ConditionInterface.

Definition at line 61 of file ConditionOnce.cpp.
