NAME

       SoCounter -

       The SoCounter class is an integer counter engine.

       The engine counts from its min value to its max value, adding the value of step each time trigger is
       touched.

SYNOPSIS

       #include <Inventor/engines/SoCounter.h>

       Inherits SoEngine.

   Public Member Functions
       virtual SoType getTypeId (void) const
           Returns the type identification of an object derived from a class inheriting SoBase. This is used for
           run-time type checking and 'downward' casting.

Detailed Description

       The SoCounter class is an integer counter engine.

       The engine counts from its min value to its max value, adding the value of step each time trigger is
       touched.

       SoCounter provides a convenient way of keeping track of the number of times some event in your
       application is triggered.

Constructor & Destructor Documentation

   SoCounter::SoCounter (void)
       Default constructor.

   SoCounter::~SoCounter (void) [protected],  [virtual]
       Destructor.

       Protected, as engines are not supposed to be explicitly deleted, but rather take care of their own
       destiny by monitoring their reference count.

Member Function Documentation

   SoType SoCounter::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
         }
       }

       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 * SoCounter::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 * SoCounter::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.

Member Data Documentation

   SoSFShort SoCounter::min
       Minimum value for counter.

   SoSFShort SoCounter::max
       Maximum value for counter.

   SoSFShort SoCounter::step
       Counter step value.

   SoSFTrigger SoCounter::trigger
       Increment counter (using step).

   SoSFShort SoCounter::reset
       Reset counter to this value. The value will be clamped between min and max, and step will be accounted
       for.

   SoEngineOutput SoCounter::output
       (SoSFShort) Output which contains the current counter value.

   SoEngineOutput SoCounter::syncOut
       (SoSFTrigger) Triggers every time counter restarts at SoCounter::min.
