Remarks

Removes the top element from the heap. Assumes < operator is defined for the template type.

@note 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

Parameter	Description
bAllowShrinking	(Optional) Tells if this call can shrink the array allocation if suitable after the discard. Default is true.
