Protected Member Functions¶

SoDetail (void)

SoDetail::~SoDetail () [virtual]¶

Destructor.

SoDetail::SoDetail (void) [protected]¶

Default constructor.

void SoDetail::initClass (void) [static]¶

Initialize relevant common data for all instances, like the type system.

void SoDetail::initClasses (void) [static]¶

Call the initClass() methods of all built-in detail classes.

(The initClass() method of user extension detail classes -- if any -- must be called explicitly by the application programmer in the application initialization code.)

SoDetail * SoDetail::copy (void) const [pure 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.

Implemented in SoConeDetail, SoCubeDetail, SoCylinderDetail, SoFaceDetail, SoLineDetail, SoNodeKitDetail, SoPointDetail, and SoTextDetail.

SoType SoDetail::getTypeId (void) const [pure 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.

Implemented in SoConeDetail, SoCubeDetail, SoCylinderDetail, SoFaceDetail, SoLineDetail, SoNodeKitDetail, SoPointDetail, and SoTextDetail.

SbBool SoDetail::isOfType (const SoType type) const¶

Returns TRUE if type is derived from (or is) this class.

SoType SoDetail::getClassTypeId (void) [static]¶

Returns the type for this class.
