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.
