Object lifetime

Time period between the creation and destruction of an object-oriented programming instance

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. For example, destruction of the variable may only destroy the reference; not the referenced object.
