PARENT CLASS FUNCTIONS
The OpenGL Performer class pfCombiner is derived from the parent class
pfObject, so each of these member functions of class pfObject are also
directly usable with objects of class pfCombiner. This is also true for
ancestor classes of class pfObject.
void* pfObject::operator new(size_t);

void* pfObject::operator new(size_t, void *arena);
void* pfObject::operator new(size_t, pfFluxMemory *fmem);
void pfObject::setUserData(void *data);
void pfObject::setUserData(int slot, void *data);
void* pfObject::getUserData(pfObject *obj);
void* pfObject::getUserData(pfObject *obj, int slot);
int pfObject::getNumUserData();
Since the class pfObject is itself derived from the parent class
pfMemory, objects of class pfCombiner can also be used with these
functions designed for objects of class pfMemory.
void* pfMemory::getData(const void *ptr);
pfType * pfMemory::getType();
int pfMemory::isOfType(pfType *type);
int pfMemory::isExactType(pfType *type);
const char * pfMemory::getTypeName();
int pfMemory::copy(pfMemory *src);
int pfMemory::compare(const pfMemory *mem);
void pfMemory::print(uint which, uint verbose, char *prefix,
FILE *file);
int pfMemory::getArena(void *ptr);
void* pfMemory::getArena();
int pfMemory::ref();
int pfMemory::unref();
int pfMemory::unrefDelete();
int pfMemory::unrefGetRef();
int pfMemory::getRef();
int pfMemory::checkDelete();

DESCRIPTION
A pfCombiner is an encapsulation of the state of all modes related to the
NV_register_combiners OpenGL extension. A pfCombiner can be used within
a pfGeoState by setting the PFSTATE_COMBINER attribute and the and the
PFEN_COMBINER state.
The function pfCombiner::getClassType returns the pfType pointer for the
class pfCombiner.
The number of active register combiners can be set with the function
pfCombiner::setActiveCombiners. The maximum number of available general
combiners can be queried with the function
pfCombiner::getMaxGeneralCombiners.
The parameter stage for pfCombiner::setGeneralInput and
pfCombiner::setGeneralOutput can take on any of the following values:
GL_COMBINER0_NV
GL_COMBINER1_NV

GL_TEXTURE1_ARB
GL_E_TIMES_F_NV (applicable only to pfCombiner::setFinalInput)

GL_EXPAND_NORMAL_NV
GL_EXPAND_NEGATE_NV
GL_HALF_BIAS_NORMAL_NV
GL_HALF_BIAS_NEGATE_NV
