Question

(GUI for our Library System.) Consider a GUI for our Library system, implemented

as a Finite State Machine. One of the options in the

ClerkMenu state is to renew a user's books.

Assuming that we have a context and a separate RenewState , construct a sequence diagram that shows how the control ows among the states of the GUI when theRenew books use-case is invoked. Do not show any details of operations behind the Facade.

* The Facade (Library) provides the following operations:

searchMembership(memberID)

that returns a member object,

getBooks(memberID)

that returns an iterator for the list of books issued to the member, and renewBook(bookID, memberID) that returns a reference to the book that was renewed.

Describe and justify any other assumptions that you make.
