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.
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.
References data, and SoElement::getTypeId().
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.
SoInt32Element::data [protected] |
