size_t SbNodeIdType
Type of unique ids of SoNode, used in the notification/change detection handling.
Definition: SbBasic.h:90
#define INVENTOR_API
Disable some annoying warnings on MSVC 6.
Definition: SbSystem.h:81
#define SO_ELEMENT_ABSTRACT_HEADER(className)
Macros to be called within the class definition header for a element subclass:
Definition: SoSubElement.h:99
This is the abstract base class for all state elements.
Definition: SoElement.h:96
Abstract base class for all database nodes.
Definition: SoNode.h:103
This is the abstract base class for each state element whose value is replaced whenever it is set.
virtual SoElement * copyMatchInfo() const
Create and return a copy of this element.
virtual void print(FILE *fp) const
Prints element (for debugging)
static SoElement * getElement(SoState *state, int stackIndex, SoNode *node)
Overrides SoElement::getElement() to set the nodeId in the element instance before returning it.
SbNodeIdType getNodeId() const
Return nodeId.
virtual ~SoReplacedElement()
Destructor.
static void initClass()
Initializes the SoReplacedElement class.
virtual bool matches(const SoElement *elt) const
Returns TRUE if the element matches another element, based on node-id.
virtual void init(SoState *state)
Initializes node id in element.
An SoState collects and holds state while traversing a scene graph.
