## 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::SoTimeCounter | ( | void |  | ) |

Default constructor.

## ~SoTimeCounter()

SoTimeCounter::~SoTimeCounter | ( | void |  | ) |

protected virtual

Destructor.

## Member Function Documentation

## getClassTypeId()

SoType SoTimeCounter::getClassTypeId | ( | void |  | ) |

static

This static method returns the SoType object associated with objects of this class.

## getTypeId()

SoType SoTimeCounter::getTypeId | ( | void |  | ) | const

virtual

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and "downward" casting.

Implements SoBase.

## getInputDataPtr()

const SoFieldData ** SoTimeCounter::getInputDataPtr | ( | void |  | ) |

static protected

Returns the SoFieldData class which holds information about inputs in this engine.

## getOutputDataPtr()

const SoEngineOutputData ** SoTimeCounter::getOutputDataPtr | ( | void |  | ) |

static protected

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

## getFieldData()

const SoFieldData * SoTimeCounter::getFieldData | ( | void |  | ) | const

virtual

Returns the SoFieldData class which holds information about inputs in this engine.

Reimplemented from SoFieldContainer.

## getOutputData()

const SoEngineOutputData * SoTimeCounter::getOutputData | ( | void |  | ) | const

virtual

Returns the SoEngineOutputData class which holds information about the outputs in this engine.

Implements SoEngine.

## createInstance()

void * SoTimeCounter::createInstance | ( | void |  | ) |

static

Creates a new instance of the class type corresponding to the SoType object.

## inputChanged()

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.

Reimplemented from SoEngine.

## writeInstance()

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

## timeIn

SoSFTime SoTimeCounter::timeIn

Running time. Connected to the realTime field by default.

## min

SoSFShort SoTimeCounter::min

Minimum counter value. Default value is 0.

## max

SoSFShort SoTimeCounter::max

Maximum counter value. Default value is 1.

## step

SoSFShort SoTimeCounter::step

Counter step size. Default value is 1.

## on

SoSFBool SoTimeCounter::on

Set to `FALSE` to pause the counter. Default value is `TRUE`.

## frequency

SoSFFloat SoTimeCounter::frequency

Number of complete cycles from the min value to the max value per second. Default value is 1.0.

## duty

SoMFFloat SoTimeCounter::duty

Used to weight step times. Supply one weight value per step. Default array is a single value of 1.0.

## reset

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.

## syncIn

SoSFTrigger SoTimeCounter::syncIn

Restart counter at the minimum value.

## output

SoEngineOutput SoTimeCounter::output

(SoSFShort) The counter value.

## syncOut

SoEngineOutput SoTimeCounter::syncOut

(SoSFTrigger) Triggers every cycle start.
