34  * <P>
35  * InitActive is related to the initialization of the activity of an
36  * active object. The initialization of the activity is done only once.
37  * In case of a migration, an active object restarts its activity
38  * automatically without reinitializing.
39  * </P><P>
40  * An object implementing this interface can be invoked to perform the
41  * initialization work before the activity is started. The object being
42  * reified as an active object can implement this interface or an external
43  * class can also be used.
44  * </P>
45  * <P>
46  * It is generally the role of the body of the active object to perform the
47  * call on the object implementing this interface.
