Member Function Documentation

void SoSoundElement::initClass (void) [static]This static method initializes static data for the SoSoundElement class.

Reimplemented from SoReplacedElement.

void SoSoundElement::init (SoState * state) [virtual]Initializes the element to it's default value.

Reimplemented from SoReplacedElement.

SbBool SoSoundElement::sceneGraphHasSoundNode (SoState *const state) [static]Returns the value of the sceneGraphHasSoundNode flag.

SbBool SoSoundElement::soundNodeIsPlaying (SoState *const state) [static]Returns the value of the soundNodeIsPlaying flag.

SbBool SoSoundElement::isPartOfActiveSceneGraph (SoState *const state) [static]Returns the value of the isPartOfActiveSceneGraph flag.

void SoSoundElement::push (SoState * state) [virtual]Calls the superclass' push method. Initializes the element to the default values. Uses previous element's isPartOfActiveSceneGraph flag.

Reimplemented from SoElement.

void SoSoundElement::setDefaultValues () [protected]Initializes the element to the default values. The default values for the sceneGraphHasSoundNode is FALSE. The default value for the isPartOfActiveSceneGraph flag is TRUE. the default value for the soundNodeIsPlaying flag is FALSE.
