Public Member Functions
virtual void	init (SoState *state)
	Initializes element.

virtual void	push (SoState *state)
	Push copies the values from the previous element, so set doesn't have to set them if they are set AS_IS.

virtual bool	matches (const SoElement *elt) const
	Returns TRUE if the hints match in both elements.

virtual SoElement *	copyMatchInfo () const
	Create and return a copy of this element.

virtual void	print (FILE *fp) const
	Prints element (for debugging)

Public Member Functions inherited from SoElement

	Returns TRUE if the element matches another element (of the same class, presumably) with respect to cache validity.

virtual SoElement *	copyMatchInfo () const =0

SoType	getTypeId () const
	Returns type identifier for element instance.

int	getStackIndex () const
	Returns the stack index for an element instance.

Detailed Description

All three hints must be set at the same time; to leave any hint as is, use the "AS_IS" enum value.
