Class CodeBuilder

java.lang.Object

org.objectweb.asm.MethodVisitor

com.google.template.soy.jbcsrc.restricted.CodeBuilder

public final class CodeBuilder
extends org.objectweb.asm.MethodVisitor

A MethodVisitor that acts as a substitute for GeneratorAdapter.

GeneratorAdapter has lots of convenient methods (like GeneratorAdapter.push(int)), however it is a subtype of LocalVariablesSorter which automatically renumbers local variables. This is actually fine (i think), but the problem is that it makes our debugging information (like ClassData#toString() or BytecodeProducer.trace()) very misleading since none of the local variable indices in the debug information match the indexes in the generated code, so the debug data just looks wrong.

So instead we use forwarding to reuse the safe subset of the GeneratorAdapter api and this allows us to skip past all the local variable munging.
