virtual SoElement* SoFloatElement::copyMatchInfo

(

)

const [virtual]

Implements SoElement.

static float SoFloatElement::get	(	int	stackIndex,
		SoState *	state
	)		[inline, static, protected]

Derived classes have static inline methods to pass in the stackIndex and cast the returned value to the right type.

Reimplemented from SoElement.

Reimplemented in SoCreaseAngleElement.

static void SoFloatElement::set	(	int	stackIndex,
		SoState *	state,
		float	value
	)		[static, protected]

Derived classes have static inline methods that pass in the stack index and cast their type into a float. This just gets an appropriate instance and calls the virtual set.
