Class JavaToJavaScriptCompiler

java.lang.Object

com.google.gwt.dev.jjs.JavaToJavaScriptCompiler

Direct Known Subclasses:

LibraryJavaToJavaScriptCompiler, MonolithicJavaToJavaScriptCompiler

public abstract class JavaToJavaScriptCompiler
extends Object

A base for classes that compile Java JProgram representations into corresponding Js source.
Work is split between a precompile() stage which is only called once and compilePerms() stage which is called once per permutation. This allow build systems the option of distributing and parallelizing some of the work.
