SootMethod

java.lang.Object
- soot.tagkit.AbstractHost
- - soot.SootMethod

All Implemented Interfaces:

ClassMember, MethodOrMethodContext, Host, Numberable
```
public class SootMethod
extends AbstractHost
implements ClassMember, Numberable, MethodOrMethodContext
```
Soot representation of a Java method. Can be declared to belong to a SootClass. Does not contain the actual code, which belongs to a Body. The getActiveBody() method points to the currently-active body.

    Nomair A. Naeem , January 14th 2006 Need it for the decompiler to create a new SootMethod The SootMethod can be created fine but when one tries to create a SootMethodRef there is an error because there is no declaring class set. Dava cannot add the method to the class until after it has ended decompiling the remaining method (new method added is added in the PackManager) It would make sense to setDeclared to true within this method too. However later when the sootMethod is added it checks that the method is not set to declared (isDeclared).
