## 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

## ◆ matches()

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.

## ◆ copyMatchInfo()

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.

## ◆ print()

void SoInt32Element::print | ( | FILE * | file | ) | const

virtual

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

Reimplemented from SoElement.

## ◆ set()

void SoInt32Element::set | ( | const int | index,
|  | SoState *const | state,
|  | const int32_t | value
| ) |  |

static

FIXME: write doc.

## Member Data Documentation

## ◆ data

SoInt32Element::data

protected

The 32-bit integer value of the element.
