int(* get_index_func )(void *)
void(* set_index_func )(void *, int)
Detailed Description
The SbHeapFuncs struct is used to specify functions on heap elements.
Member Data Documentation
float(* SbHeapFuncs::eval_func) (void *)
The eval_func member is a pointer to a function that should return a weight-value for a heap element. Smaller elements are extracted first from the heap.
int(* SbHeapFuncs::get_index_func) (void *)
get_index_func is a pointer to a function which should return the element's heap index. If you want to remove an element from the heap (other than the first element), or change the weight for a heap element, you must supply the two index functions. Each element must then store its heap index in its own data structures.
void(* SbHeapFuncs::set_index_func) (void *, int)
set_index_func is used to set this index value, and will be called whenever the element is moved in the heap.
