Class ImplementClassLiteralsAsFields

java.lang.Object

com.google.gwt.dev.jjs.impl.ImplementClassLiteralsAsFields

public class ImplementClassLiteralsAsFields
extends Object

Create fields to represent the mechanical implementation of class literals. Must be done after all class literals are created, but before optimizations begin. ControlFlowAnalyzer depends on this.

Class literals are implemented as static field references. The static fields are all put into the special com.google.gwt.lang.ClassLiteralHolder class. Ordinarily, accessing one of these fields would trigger a clinit to run, but we've special-cased class literal fields to evaluate as top-level code before the application starts running to avoid the clinit. Class literal factory methods are responsible for installing references to themselves on the Object.clazz field of their JS runtime prototype since getClass() is no longer an overridden method. Prototypes can be looked up via 'typeId' from the global prototypesByTypeId object, and so each class literal factory method is passed the typeId of its type.
