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.
|
virtual |
This function initializes the element type in the given SoState. It is called for the first element of each enabled element type in SoState objects.
Reimplemented from SoElement.
Reimplemented in SoGLPointSizeElement, SoGLLineWidthElement, SoLineWidthElement, SoPointSizeElement, and SoListenerGainElement.
References data, and SoElement::init().
Referenced by SoLineWidthElement::init(), SoPointSizeElement::init(), and SoListenerGainElement::init().
|
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().
|
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().
|
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().
|
static |
Static method for setting the value of an element in the given state at the given stack index.
References SoElement::getElement(), and setElt().
Referenced by SoLineWidthElement::set(), SoPointSizeElement::set(), SoListenerGainElement::set(), and set().
|
static |
Static method for setting the value of an element in the given state at the given stackIndex.
References set().
|
static |
Static method to fetch the value of the element of this type from the given state at the given stack index.
References data, and SoElement::getConstElement().
Referenced by SoLineWidthElement::get(), SoPointSizeElement::get(), and SoListenerGainElement::get().
|
virtual |
Set element value.
Reimplemented in SoGLPointSizeElement, and SoGLLineWidthElement.
References data.
Referenced by set().
|

The element's value.
