Closest Wikipedia entry:  Object lifetime — In object-oriented programming (OOP), object lifetime is the period of time between an object's creation and its destruction. In some programming contexts, object lifetime coincides with the lifetime of a variable that represents the object. In other contexts – where the object is accessed by reference – object lifetime is not determined by the lifetime of a variable.
