"Memento – an object that *contains a concrete unique snapshot of state* of "
"any object or resource: string, number, array, an instance of class and so "
"on. The uniqueness in this case does not imply the prohibition existence of "
"similar states in different snapshots. That means the state can be extracted"
" as the independent clone. Any object stored in the Memento should be *a "
"full copy of the original object rather than a reference* to the original "
"object. The Memento object is a \"opaque object\" (the object that no one "
"can or should change)."

"copy of this state and return it wrapped in a Memento. The Originator does "
"not know the history of changes. You can set a concrete state to Originator "
"from the outside, which will be considered as actual. The Originator must "

#~ "The memento pattern is implemented with three objects: the originator, a "
#~ "caretaker and a memento. The originator is some object that has an internal "
#~ "state. The caretaker is going to do something to the originator, but wants "
#~ "to be able to undo the change. The caretaker first asks the originator for a"
#~ " memento object. Then it does whatever operation (or sequence of operations)"
#~ " it was going to do. To roll back to the state before the operations, it "
#~ "returns the memento object to the originator. The memento object itself is "
#~ "an opaque object (one which the caretaker cannot, or should not, change). "
#~ "When using this pattern, care should be taken if the originator may change "
#~ "other objects or resources - the memento pattern operates on a single "
#~ "object."
