HeapRemoveAt(SizeType, EAllowShrinking)
Description
- Removes an element from the heap. Assumes < operator is defined for the template type.
-
If your array contains raw pointers, they will be automatically dereferenced during heapification. Therefore, your array will be heapified by the values being pointed to, rather than the pointers' values. The auto-dereferencing behavior does not occur with smart pointers.

Parameters
| Name | Remarks |
|---|---|
| Index | Position at which to remove item. |
| AllowShrinking | (Optional) By default, arrays with large amounts of slack will automatically shrink. Use FNonshrinkingAllocator or pass EAllowShrinking::No to prevent this. |

HeapRemoveAt(SizeType, const PREDICATE_CLASS &, EAllowShrinking)
Description
- Removes an element from the heap.
-
If your array contains raw pointers, they will be automatically dereferenced during heapification. Therefore, your predicate will be passed references rather than pointers. The auto-dereferencing behavior does not occur with smart pointers.
