NAME

       SoOnOff -

       The SoOnOff engine is a simple on/off switch.

SYNOPSIS

       #include <Inventor/engines/SoOnOff.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 SoOnOff engine is a simple on/off switch.

Constructor & Destructor Documentation

   SoOnOff::SoOnOff (void)
       Default constructor.

   SoOnOff::~SoOnOff (void) [protected],  [virtual]
       Destructor is protected because engines are reference counted.

Member Function Documentation

   SoType SoOnOff::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 * SoOnOff::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 * SoOnOff::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

   SoSFTrigger SoOnOff::on
       An input signal on this trigger makes the SoOnOff::isOn output become TRUE.

   SoSFTrigger SoOnOff::off
       An input signal on this trigger makes the SoOnOff::isOn output become FALSE.

   SoSFTrigger SoOnOff::toggle
       An input signal on this trigger toggles the TRUE or FALSE value of the SoOnOff::isOn output.

   SoEngineOutput SoOnOff::isOn
       (SoSFBool) Whether the engine is 'on' or not.

   SoEngineOutput SoOnOff::isOff
       (SoSFBool) Always the opposite value of SoOnOff::isOn.
