References

Module	Core
Header	/Engine/Source/Runtime/Core/Public/Containers/Array.h
Include	#include "Containers/Array.h"

Syntax

template<class PREDICATE_CLASS>
SizeType HeapPush
(
ElementType && InItem,
const PREDICATE_CLASS & Predicate
)

Remarks

Adds a new element to the heap.

@note 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.

Returns

The index of the new element.

Parameters

Parameter	Description
InItem	Item to be added.
Predicate	Predicate class instance.
