SoFloatElement is an abstract base class for elements that consists of a single float value.
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 single precision floating point 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 float value.

Destructor.
|
static |
This static method returns the SoType object associated with objects of this class.
|
static |
This static method returns the state stack index for the class.
|
static |
Initialize relevant common data for all instances, like the type system.
|
virtual |
Initializes the element to its default value. The default value is 0.0.
Reimplemented from SoElement.
Reimplemented in SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.
|
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.
