SoFloatElement::~SoFloatElement (void) [protected], [virtual]¶

Destructor.

void SoFloatElement::init (SoState * state) [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 SoComplexityElement, SoCreaseAngleElement, SoDecimationPercentageElement, SoFocalDistanceElement, SoFontSizeElement, SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, SoListenerGainElement, SoPointSizeElement, and SoTextureQualityElement.

SbBool SoFloatElement::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 * SoFloatElement::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 SoFloatElement::print (FILE * file) const [virtual]¶

This function is for printing element information, and is used mostly for debugging purposes.

Reimplemented from SoElement.

void SoFloatElement::set (const int stackIndex, SoState *const state, const float value) [static]¶

Static method for setting the value of an element in the given state at the given stackIndex.

float SoFloatElement::get (const int index, SoState *const state) [static]¶

Static method to fetch the value of the element of this type from the given state at the given stack index.

void SoFloatElement::setElt (float value) [virtual]¶

Set element value.

Reimplemented in SoGLPointSizeElement, and SoGLLineWidthElement.

float SoFloatElement::data [protected]¶

The element's value.
