Class ToStringGenerationVisitor

java.lang.Object

com.google.gwt.dev.jjs.ast.JVisitor

com.google.gwt.dev.jjs.impl.TextOutputVisitor

com.google.gwt.dev.jjs.impl.ToStringGenerationVisitor

All Implemented Interfaces:

TextOutput

Direct Known Subclasses:

SourceGenerationVisitor

public class ToStringGenerationVisitor
extends TextOutputVisitor

Implements a reasonable toString() for all JNodes. The goal is to print a recognizable declaration for large constructs (classes, methods) for easy use in a debugger. Expressions and Statements should look like Java code fragments.
