Member Function Documentation

SoType SoSoundElement::getClassTypeId ( void   )  [static]

This static method returns the class type.

Reimplemented from SoReplacedElement.

int SoSoundElement::getClassStackIndex ( void   )  [static]

This static method returns the state stack index for the class.

Reimplemented from SoReplacedElement.

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.

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.
