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 scene graph 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.
