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

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

protected
