SYNOPSIS

       #include <Inventor/engines/SoTransformVec3f.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 SoTransformVec3f class transforms 3D vectors by a matrix.

Constructor & Destructor Documentation

   SoTransformVec3f::SoTransformVec3f (void)
       Default constructor.

   SoTransformVec3f::~SoTransformVec3f (void) [protected],  [virtual]
       Destructor is protected because explicit destruction of engines is not allowed.

Member Function Documentation

   SoType SoTransformVec3f::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 * SoTransformVec3f::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 * SoTransformVec3f::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.
