~FChunkedFixedUObjectArray()		UObject/UObjectArray.h

Name	Type	Remarks	Include Path
bFUObjectItemIsPacked	bool		UObject/UObjectArray.h

Name	Type	Remarks	Include Path
MaxChunks	int32	Maximum number of chunks	UObject/UObjectArray.h
MaxElements	int32	Maximum number of elements	UObject/UObjectArray.h
NumChunks	int32	Number of chunks we currently have	UObject/UObjectArray.h
NumElements	int32	Number of elements we currently have	UObject/UObjectArray.h
Objects	FUObjectItem **	Primary table to chunks of pointers	UObject/UObjectArray.h
PreAllocatedObjects	FUObjectItem *	If requested, a contiguous memory where all objects are allocated	UObject/UObjectArray.h

Name	Remarks	Include Path
int32 AddRange ( int32 NumToAdd )		UObject/UObjectArray.h
int32 AddSingle()		UObject/UObjectArray.h
int32 Capacity()	Return the number max capacity of the array Thread safe, but you know, someone might have added more elements before this even returns	UObject/UObjectArray.h
int64 GetAllocatedSize()		UObject/UObjectArray.h
FUObjectItem const * GetObjectPtr ( int32 Index ) const	Return a pointer to the pointer to a given element	UObject/UObjectArray.h
FUObjectItem * GetObjectPtr ( int32 Index )		UObject/UObjectArray.h
FUObjectItem *** GetRootBlockForDebuggerVisualizers()	Return a naked pointer to the fundamental data structure for debug visualizers.	UObject/UObjectArray.h
bool IsValidIndex ( int32 Index ) const	Return if this index is valid Thread safe, if it is valid now, it is valid forever.	UObject/UObjectArray.h
int32 Num()	Return the number of elements in the array Thread safe, but you know, someone might have added more elements before this even returns	UObject/UObjectArray.h
void PreAllocate ( int32 InMaxElements, bool bPreAllocateChunks )	Expands the array so that Element[Index] is allocated. New pointers are all zero.	UObject/UObjectArray.h
void PrefetchObjectPtr ( int32 Index ) const		UObject/UObjectArray.h

Name	Remarks	Include Path	Unreal Specifiers
FUObjectItem const & operator[] ( int32 Index ) const	Return a reference to an element	UObject/UObjectArray.h
FUObjectItem & operator[] ( int32 Index )		UObject/UObjectArray.h
