#define SoEXTENDER
Provide inline template functions for abs, swap, min, max, and clamp.
Definition: SbBasic.h:154
#define SoINTERNAL
Definition: SbBasic.h:155
#define INVENTOR_API
Disable some annoying warnings on MSVC 6.
Definition: SbSystem.h:81
signed int int32_t
Definition: SbTypeDefs.h:43
#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
static const SoElement * getConstElement(SoState *state, int stackIndex)
Returns a read-only pointer to the top instance in the given element stack.
Definition: SoElement.h:234
Subclasses store a single int32_t, int, or enum value.
virtual void print(FILE *fp) const
Prints element (for debugging)
static int32_t get(int stackIndex, SoState *state)
Get value.
virtual SoElement * copyMatchInfo() const
Copy method, takes care copying the data.
int32_t data
Storage for data.
static void set(int stackIndex, SoState *state, int32_t value)
Set value.
static void set(int stackIndex, SoState *state, SoNode *, long value)
virtual bool matches(const SoElement *elt) const
Comparison based on value of int32_ts.
virtual ~SoInt32Element()
static void set(int stackIndex, SoState *state, SoNode *, int32_t value)
virtual void setElt(int32_t value)
Virtual set that subclasses can override to implement side-effect behaviors.
static void initClass()
Initializes the SoInt32Element class.
Abstract base class for all database nodes.
Definition: SoNode.h:103
An SoState collects and holds state while traversing a scene graph.
