Member Function Documentation

void * SoSoundElement::createInstance (void) [static]This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

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

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

void SoSoundElement::set (SoState *const state, SoNode *const node, SbBool scenegraphhassoundnode, SbBool soundnodeisplaying, SbBool ispartofactivescenegraph) [static]Sets the flags.

SbBool SoSoundElement::setSceneGraphHasSoundNode (SoState *const state, SoNode *const node, SbBool flag) [static]Sets the sceneGraphHasSoundNode flag.

SbBool SoSoundElement::sceneGraphHasSoundNode (SoState *const state) [static]The sceneGraphHasSoundNode flag is used to stop the SoAudioRenderAction in SoSeparator and SoVRMLGroup nodes for cases where the sub-graph doesn not contain any SoVRMLSound nodes. Returns the value of the sceneGraphHasSoundNode flag.

SbBool SoSoundElement::setSoundNodeIsPlaying (SoState *const state, SoNode *const node, SbBool flag) [static]Sets the soundNodeIsPlaying flag.

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

SbBool SoSoundElement::setIsPartOfActiveSceneGraph (SoState *const state, SoNode *const node, SbBool flag) [static]Sets the isPartOfActiveSceneGraph flag.

SbBool SoSoundElement::isPartOfActiveSceneGraph (SoState *const state) [static]The isPartOfActiveSceneGraph flag is used to make SoVRMLSound that are below inactive parts of the scenegraph (i.e. below a SoSwitch or SoLOD node) stop playing. 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::pop (SoState * state, const SoElement * prevTopElement) [virtual]Calls the superclass' pop method. 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.
