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.

Referenced by copyMatchInfo(), get(), init(), print(), and setElt().
