Detailed DescriptionThe SoElapsedTime class is a controllable time source engine. The additional functionality provided by this engine versus just connecting to the realTime global field is the ability to control the speed of the time source plus logic to reset, stop and restart it. Simple usage example, combined with SoComposeRotation: #Inventor V2.1 ascii
Separator {
Transform {
rotation =
ComposeRotation { axis 0 1 0 angle =
ElapsedTime { }.timeOut
}.rotation
}
Cube { }
}See also SoTimeCounter
Constructor & Destructor Documentation
SoElapsedTime::SoElapsedTime (void)Default constructor. References SoField::connectFrom(), SoDB::getGlobalField(), SbTime::getValue(), on, pause, reset, speed, timeIn, timeOut, and SbTime::zero().
SoElapsedTime::~SoElapsedTime () [protected]Destructor.
Member Function Documentation
SoType SoElapsedTime::getTypeId (void) const [virtual]Returns the type identification of an object derived from a class inheriting SoBase. This is used for run-time 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
}
else if (node->getTypeId().isOfType(SoGroup::getClassTypeId())) {
SoGroup * group = (SoGroup *)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 pre-defined 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 toplevel superclasses for the various class groups. Implements SoBase.
const SoFieldData * SoElapsedTime::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.
const SoEngineOutputData * SoElapsedTime::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.
void SoElapsedTime::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. References SoField::connectFrom(), SoField::disconnect(), SoField::getConnectedField(), SoDB::getGlobalField(), SoField::isDefault(), SoField::setDefault(), timeIn, and SoEngine::writeInstance().
Member Data Documentation
SoSFTime SoElapsedTime::timeInInput time value. Default connected to the global realTime field. Referenced by SoElapsedTime(), and writeInstance().
SoSFFloat SoElapsedTime::speedDecides how fast the timer should run, measured versus 'real time' from the timeIn field. Default value is 1.0. A negative value makes the time go backward. Referenced by SoElapsedTime().
SoSFBool SoElapsedTime::onShuts timer on and off. Will restart at the same position. Referenced by SoElapsedTime(), SoPendulum::SoPendulum(), and SoShuttle::SoShuttle().
SoSFBool SoElapsedTime::pauseShuts timer on and off. Will restart at the position it would have been if not paused (i.e. doesn't 'lose time'). Referenced by SoElapsedTime().
SoSFTrigger SoElapsedTime::resetRestart timer at 0. Referenced by SoElapsedTime().
SoEngineOutput SoElapsedTime::timeOut(SoSFTime) Output time value. Starts at 0. Referenced by SoElapsedTime(), SoPendulum::SoPendulum(), and SoShuttle::SoShuttle().
