The allocation points in the code are used to approximate the set of objects created by a program, while the OFG is used to determine the inter -object ... the loan (method calls numbered 4. 1 and 4. 2). Then, the operation addLoan is invoked both on the User (call 4. 3) and on the Document (call 4. 4) object. The effect...

Available tools for Object Oriented design typically offer a facility for the recovery of class diagrams from the code, which include this kind of syntactic information. eLib ... type of the con- tained objects is obtained by defining gen and kill sets of each OFG node. Two different kinds of flow information can be used to infer the...

... with the aim of remodularizing them [4, 54, 99]. Some of such features apply to Object Oriented software as well, and can be used to derive a package diagram from the source code of the classes ... issued inside the code of the classes under analysis. A concept consists of a set of classes performing a set of same method calls, which are not simultaneously made by the c...
