Detailed Description

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


Constructor & Destructor Documentation

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

Destructor.


Member Function Documentation

void SoFloatElement::initClass void   )  [static]
 

Initialize relevant common data for all instances, like the type system.

Reimplemented from SoElement.

Reimplemented in SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, and SoPointSizeElement.

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 SoGLLineWidthElement, SoGLPointSizeElement, SoLineWidthElement, and SoPointSizeElement.

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  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  value  )  [virtual]
 

Set element value.

Reimplemented in SoGLLineWidthElement, and SoGLPointSizeElement.


Member Data Documentation

float SoFloatElement::data [protected]
