Syntax
class FArenaPointer
Remarks
Tagged Arena Pointer
Stores an arena ID alongside a pointer. On 64-bit architectures the arena ID can be encoded in the otherwise unused MSB part of the pointer for zero memory overhead vs a regular pointer. For 32-bit architectures the arena ID is stored in a separate member.
A null pointer can still have an arena ID, which is useful for cases where you have a container that starts out empty but still want to track which arena should be used for subsequent allocations.
