SYNOPSIS

       #include <Inventor/VRMLnodes/SoVRMLSensor.h>

       Inherits SoNode.

       Inherited by SoVRMLDragSensor.

   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.

   Static Public Member Functions
       static SoType getClassTypeId (void)
       static void initClass (void)

   Public Attributes
       SoSFBool isActive
       SoSFBool enabled

Detailed Description

       The SoVRMLSensor class is an abstract superclass for VRML sensors.

Member Function Documentation

   SoType SoVRMLSensor::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.

       Reimplemented in SoVRMLDragSensor, SoVRMLSphereSensor, SoVRMLCylinderSensor, and
       SoVRMLPlaneSensor.

   const SoFieldData * SoVRMLSensor::getFieldData (void) const [protected],  [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.

       Reimplemented in SoVRMLDragSensor, SoVRMLSphereSensor, SoVRMLCylinderSensor, and
       SoVRMLPlaneSensor.
