sootup.interceptors.UnusedLocalEliminator

All Implemented Interfaces:

BodyInterceptor

public class UnusedLocalEliminator
extends Object
implements BodyInterceptor

The UnusedLocalEliminator removes any unused locals from the method. TODO: ms: it basically collects all locals and assigns the collection of Locals to the Body... i.e. its use replaces the need of a validator and the manual assignment of the Locals to the body.
