Class MethodCallTightener

java.lang.Object

com.google.gwt.dev.jjs.impl.MethodCallTightener

public class MethodCallTightener
extends Object

Update polymorphic method calls to tighter bindings based on the type of the qualifier. For a given polymorphic method call to a non-final target, see if the static type of the qualifer would let us target an override instead. This is possible because the qualifier might have been tightened by TypeTightener. For example, given the code:

   List foo = new ArrayList();
   foo.add("bar");
 

The type of foo is tightened by TypeTightener from type List to be of type ArrayList. This means that MethodCallTightener can analyze the polymorphic call List.add() on foo and tighten it to the more specific ArrayList.add().
