    • request

      default MemorySegment request(long newByteSize)
      Request a new heap MemorySegment with the given newByteSize. Because we do not have a reference to an Arena, the default here is to allocate a new MemorySegment on the heap. It is up to the user to override this as appropriate.
      Parameters:
      newByteSize - The new byteSize being requested.
      Returns:
      new MemorySegment with the requested byteSize.

    • requestClose

      default void requestClose(MemorySegment prevSeg)
      Request to close the given MemorySegment. Because we do not have a reference to an Arena, the default here is to do nothing. It is up to the user to override this as appropriate.
      Parameters:
      prevSeg - the previous MemorySegment to be closed.
