man SoInt32Element (Fonctions bibliothèques) -

NAME

SoInt32Element -

SYNOPSIS



#include <Inventor/elements/SoInt32Element.h>

Inherits SoElement.

Detailed Description

The SoInt32Element class is the base class for elements that simply store a 32-bit integer.

This is the superclass of elements where the new element data replaces the old data, and where the data the element stores is a simple 32-bit integer value.

This element is like a convenient light-weight version of the SoReplacedElement. It differs from the SoReplacedElement in that the set() and get() methods are already implemented, since it is known that subclasses will still contain just a single 32-bit integer value.

Member Function Documentation

SoType SoInt32Element::getClassTypeId (void) [static]

This static method returns the class type.

Reimplemented from SoElement.

int SoInt32Element::getClassStackIndex (void) [static]

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

Reimplemented from SoElement.

void SoInt32Element::initClass (void) [static]

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

Reimplemented from SoElement.

SbBool SoInt32Element::matches (const SoElement * element) const [virtual]

This function returns TRUE is the element matches another element (of the same class), with respect to cache validity.

If the application programmer's extension element has a matches() function, it should also have a copyMatchInfo() function.

Implements SoElement.

SoElement * SoInt32Element::copyMatchInfo (void) const [virtual]

This function creates a copy of the element that contains enough information to enable the matches() function to work.

Used to help with scenegraph traversal caching operations.

Implements SoElement.

void SoInt32Element::print (FILE * file) const [virtual]

This function is for printing element information, and is used mostly for debugging purposes.

Reimplemented from SoElement.

void SoInt32Element::set (const int index, SoState *const state, const int32_t value) [static]

FIXME: write doc.

Member Data Documentation

SoInt32Element::data [protected]

The 32-bit integer value of the element.
