[heading Description]
|
||
|
|
|
||
|
|
`make_heap` turns `rng` into a heap.
|
||
|
|
|
||
|
|
The ordering relationship is determined by using `operator<` in the non-predicate versions, and by evaluating `pred` in the predicate versions.
|
||
|
|
|
||
|
|
[heading Definition]
|
||
|
|
|
||
|
|
Defined in the header file `boost/range/algorithm/heap_algorithm.hpp`
|
||
|
|
|
||
|
|
[heading Requirements]
|
||
|
|
|
||
|
|
[*For the non-predicate versions:]
|
||
|
|
|
||
|
|
* `RandomAccessRange` is a model of the __random_access_range__ Concept.
|
||
|
|
* `RandomAccessRange` is mutable.
|
||
|
|
* `RandomAccessRange`'s value type is a model of the `LessThanComparableConcept`.
|
||
|
|
* The ordering of objects of type `RandomAccessRange`'s value type is a [*/strict weak ordering/], as defined in the `LessThanComparableConcept` requirements.
|
||
|
|
|
||
|
|
[*For the predicate versions:]
|
||
|
|
|
||
|
|
* `RandomAccessRange` is a model of the __random_access_range__ Concept.
|
||
|
|
* `RandomAccessRange` is mutable.
|
||
|
|
* `Compare` is a model of the `StrictWeakOrderingConcept`.
|
||
|
|
* `RandomAccessRange`'s value type is convertible to both of `Compare`'s argument types.
|
||
|
|
|
||
|
|
[heading Complexity]
|
||
|
|
|
||
|
|
Linear. At most `3 * distance(rng)` comparisons.
