NAME

SoInt32Element -

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.

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.

SoReplacedElement, SoFloatElement, SoAccumulatedElement

Member Function Documentation

void SoInt32Element::initClass (void) [static]Initialize relevant common data for all instances, like the type system.

Reimplemented from 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.

References SoType::createInstance(), data, and SoElement::getTypeId().

void SoInt32Element::print (FILE * file) const [virtual]This function is for printing element information, and is used mostly for debugging purposes.

Reimplemented from SoElement.

References data, SoType::getName(), SbName::getString(), and SoElement::getTypeId().

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.
