NAME

       SoLineDetail -

       The SoLineDetail class is for storing detailed 3D line information.

       Instances of this class are used among other things for storing information about lines
       after pick operations, and for storing information returned to tessellation callbacks.

Detailed Description

       The SoLineDetail class is for storing detailed 3D line information.

       Instances of this class are used among other things for storing information about lines
       after pick operations, and for storing information returned to tessellation callbacks.

Constructor & Destructor Documentation

   SoLineDetail::SoLineDetail (void)
       Default constructor sets up an empty, non-valid detail specification.

   SoLineDetail::~SoLineDetail () [virtual]
       Destructor.

Member Function Documentation

   SoType SoLineDetail::getTypeId (void) const [virtual]
       Returns the type identification of a detail derived from a class inheriting SoDetail. This
       is used for run-time type checking and 'downward' casting.

       Usage example:

       void fuhbear(SoDetail * detail)
       {
         if (detail->getTypeId() == SoFaceDetail::getClassTypeId()) {
           // safe downward cast, know the type
           SoFaceDetail * facedetail = (SoFaceDetail *)detail;
         }
         return; // ignore if not a SoFaceDetail
       }

       For application programmers wanting to extend the library with new detail classes: 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 Inventor/nodes/SoSubDetail.h: SO_DETAIL_SOURCE and
       SO_DETAIL_INIT_CLASS.

       Implements SoDetail.

   SoDetail * SoLineDetail::copy (void) const [virtual]
       Return a deep copy of ourself.

       Note that if the Coin library has been built as a DLL under Microsoft Windows and you use
       this method from application code, you must make sure that both the Coin DLL and the
       application executable is using the same instance of a C Run-Time (CRT) library.
       Otherwise, you will get memory heap corruption upon deallocating the returned instances,
       eventually leading to mysterious crashes.

       Implements SoDetail.

   const SoPointDetail * SoLineDetail::getPoint0 (void) const
       Returns SoPointDetail describing the line start point.

   const SoPointDetail * SoLineDetail::getPoint1 (void) const
       Returns SoPointDetail describing the line end point.

   int SoLineDetail::getLineIndex (void) const
       Returns the index of this line within the lineset node it is part of.

   int SoLineDetail::getPartIndex (void) const
       Returns the index of this line within the complex shape node it is part of.

   void SoLineDetail::setPoint0 (const SoPointDetail *constdetail)
       Stores information about line's start point. Used internally from library client code
       setting up a SoLineDetail instance.

       See Also:
           getPoint0()

   void SoLineDetail::setPoint1 (const SoPointDetail *constdetail)
       Stores information about line's end point. Used internally from library client code
       setting up a SoLineDetail instance.

       See Also:
           getPoint1()

   void SoLineDetail::setLineIndex (const intidx)
       Used internally from library client code setting up a SoLineDetail instance.

       See Also:
           getLineIndex()

   void SoLineDetail::setPartIndex (const intidx)
       Used internally from library client code setting up a SoLineDetail instance.

       See Also:
           getPartIndex()

   void SoLineDetail::incLineIndex (void)
       Convenience method for library client code when setting up a SoLineDetail instance to use
       the line index as a counter.

   void SoLineDetail::incPartIndex (void)
       Convenience method for library client code when setting up a SoLineDetail instance to use
       the part index as a counter.
