org.objectweb.asm.commons.GeneratorAdapter

A {@link org.objectweb.asm.MethodVisitor} with convenient methods to generatecode. For example, using this adapter, the class below

 public class Example { public static void main(String[] args) { System.out.println("Hello world!"); } }

can be generated as follows:

 ClassWriter cw = new ClassWriter(true); cw.visit(V1_1, ACC_PUBLIC, "Example", null, "java/lang/Object", null); Method m = Method.getMethod("void <init> ()"); GeneratorAdapter mg = new GeneratorAdapter(ACC_PUBLIC, m, null, null, cw); mg.loadThis(); mg.invokeConstructor(Type.getType(Object.class), m); mg.returnValue(); mg.endMethod(); m = Method.getMethod("void main (String[])"); mg = new GeneratorAdapter(ACC_PUBLIC + ACC_STATIC, m, null, null, cw); mg.getStatic(Type.getType(System.class), "out", Type.getType(PrintStream.class)); mg.push("Hello world!"); mg.invokeVirtual(Type.getType(PrintStream.class), Method.getMethod("void println (String)")); mg.returnValue(); mg.endMethod(); cw.visitEnd();
