TFPHashObject is a TObject descendent which is aware of the TFPHashObjectList class. It has a name property and an owning list: if the name is changed, it will reposition itself in the list which owns it. It offers methods to change the owning list: the object will correctly remove itself from the list which currently owns it, and insert itself in the new list.
