.SH "Detailed Description"
.PP 
The \fBSbHeapFuncs\fP struct is used to specify functions on heap elements\&. 
.SH "Member Data Documentation"
.PP 
.SS "SbHeapFuncs::eval_func"
The \fIeval_func\fP 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\&. 
.SS "SbHeapFuncs::get_index_func"
\fIget_index_func\fP 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\&. 
.SS "SbHeapFuncs::set_index_func"
\fIset_index_func\fP is used to set this index value, and will be called whenever the element is moved in the heap\&.
