SoTimeCounter - The SoTimeCounter class is an integer counter engine. The SoTimeCounter engine is by default connected to the realTime global field, and does stepwise updates on the SoTimeCounter::output field according to the field settings.

void SoTimeCounter::initClass (void) [static] Sets up initialization for data common to all instances of this class, like submitting necessary information to the Coin type system. Reimplemented from SoEngine. void SoTimeCounter::inputChanged (SoField *which) [protected, virtual] Called when an input is changed. The default method does nothing, but subclasses may override this method to do The Right Thing when a specific field is changed. Called when an input is changed. The default method does nothing, but subclasses may override this method to do the The Right Thing when a specific field is changed. Reimplemented from SoEngine. void SoTimeCounter::writeInstance (SoOutput *out) [protected, virtual] Writes all the fields contained in this instance to the output stream within out. This method is solely called from the write methods of fields. Either from SoField if the write is done because of a field-to-field connection, or from one of the fields which may actually write SoFieldContainer instances, i.e. SoSFNode, SoMFNode, SoSFEngine, SoMFEngine, SoSFPath and SoMFPath. This method, in addition to the ordinary write() method of SoNode, needs to be present since the fields don't have a write action instance in their writeValue() method, and writeInstance() will create a new SoWriteAction and call continueToApply() on it. Reimplemented from SoEngine.
Member Data Documentation
SoSFTime SoTimeCounter::timeIn Running time. Connected to the realTime field by default. SoSFShort SoTimeCounter::min Minimum counter value. Default value is 0. SoSFShort SoTimeCounter::max Maximum counter value. Default value is 1. SoSFShort SoTimeCounter::step Counter step size. Default value is 1. SoSFBool SoTimeCounter::on Set to FALSE to pause the counter. Default value is TRUE. SoSFFloat SoTimeCounter::frequency Number of complete cycles from the min value to the max value per second. Default value is 1.0. SoMFFloat SoTimeCounter::duty Used to weight step times. Supply one weight value per step. Default array is a single value of 1.0. SoSFShort SoTimeCounter::reset Manually set the counter to some value. If SoTimeCounter::reset is set below the SoTimeCounter::min value or above the SoTimeCounter::max value it will be clamped to the closest boundary value. SoSFTrigger SoTimeCounter::syncIn Restart counter at the minimum value. SoEngineOutput SoTimeCounter::output (SoSFShort) The counter value. SoEngineOutput SoTimeCounter::syncOut (SoSFTrigger) Triggers every cycle start.
