First Case

The following code will generate.

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

The following is code to generate preceding case.

DummyClass dummy = new DummyClass("FirstCase").public_()
       .newMethod("main").public_().static_().argTypes(String[].class)
       .body(new MethodBody(){
				public void body(LocalVariable... args) {
					getType(System.class).field("out").call("println", val("Hello ASMSupport."))
					return_();
				}
       });
Class<?> FirstCaseClass = dummy.build();
Method mainMethod = FirstCaseClass.getMethod("main", String[].class);
mainMethod.invoke(FirstCaseClass, mainMethod);

Sample : JSON & Proxy

The JSON sample under the package "cn.wensiqun.asmsupport.sample.client.json下", run the "cn.wensiqun.asmsupport.sample.client.json.demo.Runner" main method, and you can get the generated class in folder "target/asmsupport-test-generated".

The Proxy sample under the package "cn.wensiqun.asmsupport.sample.client.proxy", run the cn.wensiqun.asmsupport.sample.client.proxy.demo.Runner main method, and you can get the generated class in folder "target/asmsupport-test-generated".
