24 | [heading Description] | |
25 | ||
26 | `sort_heap` turns a heap into a sorted range. | |
27 | ||
28 | The ordering relationship is determined by using `operator<` in the non-predicate versions, and by evaluating `pred` in the predicate versions. | |
29 | ||
30 | [heading Definition] | |
31 | ||
32 | Defined in the header file `boost/range/algorithm/heap_algorithm.hpp` | |
33 | ||
34 | [heading Requirements] | |
35 | ||
36 | [*For the non-predicate versions:] | |
37 | ||
38 | * `RandomAccessRange` is a model of the __random_access_range__ Concept. | |
39 | * `RandomAccessRange` is mutable. | |
40 | * `RandomAccessRange`'s value type is a model of the `LessThanComparableConcept`. | |
41 | * The ordering of objects of type `RandomAccessRange`'s value type is a [*/strict weak ordering/], as defined in the `LessThanComparableConcept` requirements. | |
42 | ||
43 | [*For the predicate versions:] | |
44 | ||
45 | * `RandomAccessRange` is a model of the __random_access_range__ Concept. | |
46 | * `RandomAccessRange` is mutable. | |
47 | * `Compare` is a model of the `StrictWeakOrderingConcept`. | |
48 | * `RandomAccessRange`'s value type is convertible to both of `Compare`'s argument types. | |
49 | ||
50 | [heading Precondition:] | |
51 | ||
52 | `rng` is a heap. | |
53 | ||
54 | [heading Complexity] | |
55 | ||
56 | At most `N * log(N)` comparisons, where `N` is `distance(rng)`. | |
