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  )
protectedvirtual

Destructor.

Member Function Documentation

◆ 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.

Usage example:

void foo(SoNode * node)
{
if (node->getTypeId() == SoFile::getClassTypeId()) {
SoFile * filenode = (SoFile *)node; // safe downward cast, knows the type
}
}

For application programmers wanting to extend the library with new nodes, engines, nodekits, draggers or others: this method needs to be overridden in all subclasses. This is typically done as part of setting up the full type system for extension classes, which is usually accomplished by using the predefined macros available through for instance Inventor/nodes/SoSubNode.h (SO_NODE_INIT_CLASS and SO_NODE_CONSTRUCTOR for node classes), Inventor/engines/SoSubEngine.h (for engine classes) and so on.

For more information on writing Coin extensions, see the class documentation of the top level superclasses for the various class groups.

Implements SoBase.

◆ getFieldData()

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

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoFieldContainer.

◆ getOutputData()

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

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Implements SoEngine.

◆ inputChanged()

void SoTimeCounter::inputChanged ( SoField which)
protectedvirtual

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)
protectedvirtual

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.
