Member Function Documentation

getClassTypeId()

static SoType SoDepthBufferElement::getClassTypeId ( void  )

static

This static method returns the SoType object associated with objects of this class.

This static method returns the class type.

getClassStackIndex()

static int SoDepthBufferElement::getClassStackIndex ( void  )

static

This static method returns the state stack index for the class.

createInstance()

void * SoDepthBufferElement::createInstance ( void  )

static

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Creates a new instance of the class type corresponding to the SoType object.

initClass()

void SoDepthBufferElement::initClass ( void  )

static

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

set()
