The SoListenerGainElement class stores the SoListener gain during a scene graph traversal.
This gain is set by SoListener nodes during audio rendering. The SoListenerGainElement is used when the SoVRMLSound nodes render themselves.
Be aware that this class is an extension for Coin, and it is not available in the original SGI Open Inventor v2.1 API.

The destructor.
This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.
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 SoFloatElement.
References SoFloatElement::data, and SoFloatElement::init().

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
References set().
Returns the element value.
