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

DESCRIPTION
pfBoundary defines a trim curve in UV space. It can be either a discrete
or continuous curve. For the purpose of topology construction (-
pfBoundary), an edge contains an index to the boundary list in the class
pfBoundary.
new(arena) allocates a pfBoundary from the specified memory arena, or
from the process heap if arena is NULL. new allocates a pfBoundary from
the default memory arena (see pfGetSharedArena). Like other pfObjects,
pfBoundarys cannot be created statically, automatically on the stack or
in arrays. pfBoundarys should be deleted with pfDelete rather than the
delete operator.
pfBoundary::getClassType returns the pfType* for the class pfBoundary.
the pfType* returned by pfBoundary::getClassType is the same as the
pfType* returned by invoking the virtual function getType on any instance
of class pfBoundary. Because OpenGL Performer allows subclassing of
built-in types, when decisions are made based on the type of an object,
it is usually better to use the member function isOfType to test if an
object is of a type derived from a Performer type rather than to test for
strict equality of the pfType*'s.
pfBoundary::getBoundary returns the boundary id of the boundary
associated with this edge.
pfBoundary::getBoundaryDir returns the boundary direction set in
pfBoundary::setBoundaryDir.
pfBoundary::getContCurve returns a pointer to the continuous 2D curve
representing this edge. Returns NULL if the edge is not represented by a
continous curve.

pfBoundary::getDisCurve returns a pointer to the discrete 2D curve
representing this edge. Returns NULL if the edge is not represented by a
discrete curve.
pfBoundary::setContCurve sets the continuous curve to be c. It also
references c.
pfBoundary::setDisCurve sets the discrete curve to be d. It also
references d.
pfBoundary::getBoundary returns the boundary id of the boundary
associated with this edge.
pfBoundary::setBoundary sets the boundary id.
pfBoundary::setBoundaryDir when the value is -1, it indicates that if we
evaluate (3D space) this trim curve from beginT to endT, the XYZ points
are in the reverse order of the 'xyzBoundary' in the corresponding
boundary. When the value is 1, if indicates that the order is the same.
pfBoundary::getBoundaryDir returns the boundary direction set in
pfBoundary::setBoundaryDir.
