Member Function Documentation

void SoFloatElement::initClass (  void )  [static]

Initialize relevant common data for all instances, like the type system. Reimplemented from SoElement. Reimplemented in SoPointSizeElement, SoGLPointSizeElement, SoLineWidthElement, and SoGLLineWidthElement.

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 SoPointSizeElement, SoGLPointSizeElement, SoLineWidthElement, and SoGLLineWidthElement.

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. Reimplemented from 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. Reimplemented from 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 index, SoState *const state, SoNode *const node, const float value )  [static]

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

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 val )  [virtual]

Set element value. Reimplemented in SoGLPointSizeElement, and SoGLLineWidthElement.
