Detailed Description

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.


Constructor & Destructor Documentation

SoTimeCounter::SoTimeCounter void   ) 
 

Default constructor.

SoTimeCounter::~SoTimeCounter  )  [protected, virtual]
 

Destructor.


Member Function Documentation

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 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.

Reimplemented from SoEngine.


Member Data Documentation

SoSFTime SoTimeCounter::timeIn
 

Running time. Connected to the realTime field by default.

SoSFShort SoTimeCounter::min
 

Minimum counter value.

SoSFShort SoTimeCounter::max
 

Maximum counter value.

SoSFShort SoTimeCounter::step
 

Counter step size.

SoSFBool SoTimeCounter::on
 

Set to FALSE to pause the counter.

SoSFFloat SoTimeCounter::frequency
 

Number of complete cycles from the min value to the max value per second.

SoMFFloat SoTimeCounter::duty
 

Used to weight step times. Supply one weight value per step.

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.
