Detailed DescriptionThe SbHeap class is a generic heap class. FIXME: write doc Note: SbHeap is an extension versus the Open Inventor API.
Constructor & Destructor Documentation
SbHeap::SbHeap (const SbHeapFuncs & hFuncs, const int initsize = 1024)Constructor. hFuncs specifies the functions for modifying and returning information about the heap object, initsize specifies the initial number of allocated elements. This array will automatically grow when necessary, but if you know approximately how many elements the heap will contain, you should supply this to avoid some reallocs.
SbHeap::~SbHeap (void)Destructor.
Member Function Documentation
void SbHeap::emptyHeap (void)Removes all the elements from the heap.
int SbHeap::size (void) constReturns the number of elements in the heap.
int SbHeap::add (void * obj)Adds an element to the heap. Returns the element's heap position.
void SbHeap::remove (const int idx)Removes an element from the heap.
void SbHeap::remove (void * obj)This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
Returns and removes the first element in the heap, or NULL if heap is empty.
void * SbHeap::getMin (void)Returns the first element in the heap, or NULL if heap is empty.
void * SbHeap::operator[] (const int idx)Returns the heap element at index idx in the heap.
void SbHeap::newWeight (void * obj, int hpos = −1)Fixes heap if necessary when the element at hpos has changed weight. If you know the element's heap position you can supply it in hpos.
SbBool SbHeap::buildHeap (SbBool(*)(float percentage, void *data) progresscb = NULL, void * data = NULL)Builds heap out of randomly ordered data-structure.
SbBool SbHeap::traverseHeap (SbBool(*)(void *, void *) func, void * userdata) constTraverses each heap elements, and calls func for each element.
