Syntax

template<class PREDICATE_CLASS>
void HeapRemoveAt
(
    SizeType Index,
    const PREDICATE_CLASS & Predicate,
    bool bAllowShrinking
)

Remarks

Removes an element from 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.

Parameters

Parameter	Description
Index	Position at which to remove item.
Predicate	Predicate class instance.
bAllowShrinking	(Optional) Tells if this call can shrink the array allocation if suitable after the remove (default = true).
