      soot.BodyTransformer
          ptolemy.copernicus.java.DeadObjectEliminator

public class DeadObjectEliminator
extends soot.BodyTransformer

A transformer that removes unnecessary object creations. If an attribute, type or token is created, but never used anywhere, then it can be safely removed. This is possible because types and tokens are immutable, and we know that the attribute constructor will not have any interesting side effects after code generation is completed.
