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

SoType SoInt32Element::getClassTypeId

(

void

)

[static]

This static method returns the class type.

Reimplemented from SoElement.

int SoInt32Element::getClassStackIndex

(

void

)

[static]

This static method returns the state stack index for the class.

Reimplemented from SoElement.

void SoInt32Element::initClass

(

void

)

[static]

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoElement.

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.
