A Soot user should never reference them explicitly, only the interfaces, e.g., use InvokeExpr instead of JInvokeExpr. To construct instances of these types use Jimple.v().newXXX(). The Jimple singleton class contains factory methods for all the different Jimple language constructs.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>Now let’s move on to method references. You first need to get hold of the method you want to reference. The SootMethod class has a method called makeRef() to then create a reference. To get a method, use Scene.v().getMethod(). You can also take a SootClass and get the method from there, that’s equivalent.<o:p></o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span lang=EN-US style='font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D'>A Value is essentially the base class of everything that can be used as an expression in Soot.
