NAME

       SbHeapFuncs -

       The SbHeapFuncs struct is used to specify functions on heap elements.

SYNOPSIS

       #include <Inventor/SbHeap.h>

   Public Attributes
       float(* eval_func )(void *)
       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

   SbHeapFuncs::eval_func 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.
   SbHeapFuncs::get_index_func 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.
   SbHeapFuncs::set_index_func set_index_func is used to set this index value, and will be called
       whenever the element is moved in the heap.
