+ * AWT native interface (new in JDK 1.3)

+ * legacy C and C++ applications to Java and to target the needs of the
+ * community who, at present, wish to do their own native rendering to canvases
+ * for performance reasons.  Standard extensions such as Java3D also require a
+ * means to access the underlying native data structures of AWT.
+ *
+ * There may be future extensions to this API depending on demand.
+ *
+ * A VM does not have to implement this API in order to pass the JCK.
+ * It is recommended, however, that this API is implemented on VMs that support

+ *
+ * Since this is a native API, any program which uses it cannot be considered
+ * 100% pure java.

-## ByteKit
-
-
-## 目标
-
-1. 之前的Arthas里的字节码增强，是通过asm来处理的，代码逻辑不好修改，理解困难
-1. 基于ASM提供更高层的字节码处理能力，面向诊断/APM领域，不是通用的字节码库
-1. ByteKit期望能提供一套简洁的API，让开发人员可以比较轻松的完成字节码增强
-
-## 对比

-
-
-## 特性
-
-### 1. 丰富的注入点支持
-
-* `@AtEnter` 函数入口
-* `@AtExit` 函数退出
-* `@AtExceptionExit` 函数抛出异常
-* `@AtFieldAccess` 访问field
-* `@AtInvoke` 在method里的子函数调用
-* `@AtInvokeException` 在method里的子函数调用抛出异常
-* `@AtLine` 在指定行号
-* `@AtSyncEnter` 进入同步块，比如`synchronized`块
-* `@AtSyncExit` 退出同步块
-* `@AtThrow`  代码里显式`throw`异常点
-
-
-### 2. 动态的Binding
-
-* `@Binding.This` this对象
-* `@@Binding.Class` Class对象
-* `@Binding.Method` 函数调用的 Method 对象
-* `@Binding.MethodName` 函数的名字
-* `@Binding.MethodDesc` 函数的desc
-* `@Binding.Return` 函数调用的返回值
-* `@Binding.Throwable` 函数里抛出的异常
-* `@Binding.Args` 函数调用的入参
-* `@Binding.ArgNames` 函数调用的入参的名字
-
-
-* `@Binding.LocalVars` 局部变量
-* `@Binding.LocalVarNames` 局部变量的名字
-* `@Binding.Field` field对象属性字段
-
-
-* `@Binding.InvokeArgs` method里的子函数调用的入参
-* `@Binding.InvokeReturn` method里的子函数调用的返回值
-* `@Binding.InvokeMethodName` method里的子函数调用的名字
-* `@Binding.InvokeMethodOwner`  method里的子函数调用的类名
-* `@Binding.InvokeMethodDeclaration` method里的子函数调用的desc
-
-
-* `@Binding.Line` 行号
-* `@Binding.Monitor` 同步块里监控的对象
-
-
-### 3. 可编程的异常处理
-
-* `@ExceptionHandler` 在插入的增强代码，可以用`try/catch`块包围起来
-
-### 4. inline支持
-
-增强的代码 和 异常处理代码都可以通过 inline技术内联到原来的类里，达到最理想的增强效果。
-
-### 5. invokeOrigin 技术
-
-通常，我们要增强一个类，就想要办法在函数前后插入一个static的回调函数，但这样子局限太大。那么有没有更灵活的方式呢？
-
-比如有一个 hello() 函数： 
-
-```java
-    public String hello(String str) {
-        return "hello " + str;
-    }
-```
-
-我们想对它做增强，那么可以编写下面的代码：
-
-```java
-    public String hello(String str) {
-        System.out.println("before");
-        Object value = InstrumentApi.invokeOrigin();
-        System.out.println("after, result: " + value);
-        return object;
-    }
-```
-
-增强后的结果是：
-
-```java
-    public String hello(String str) {
-        System.out.println("before");
-        Object value = "hello " + str;
-        System.out.println("after, result: " + value);
-        return object;
-    }
-```
-
-**这种方式可以随意插入代码，非常灵活。**
-
-## 示例
-
-以`ByteKitDemo.java`为例说明，[[查看源文件](src/test/java/com/example/ByteKitDemo.java)]。
-
-### 1. 定义注入点和Binding数据
-
-* 在下面的 SampleInterceptor 时定义了要注入 `@AtEnter`/`@AtExit`/`@AtExceptionExit`三个地方，
-* 用`@Binding`绑定了不同的数据
-* 在`@AtEnter`里配置了 `inline = true`，则说明插入的`SampleInterceptor#atEnter`函数本身会被inline掉
-* 配置了 `suppress = RuntimeException.class` 和 `suppressHandler = PrintExceptionSuppressHandler.class`，说明插入的代码会被 `try/catch` 包围
-
-```java
-    public static class SampleInterceptor {
-
-        @AtEnter(inline = true, suppress = RuntimeException.class, suppressHandler = PrintExceptionSuppressHandler.class)
-        public static void atEnter(@Binding.This Object object, 
-                @Binding.Class Object clazz,
-                @Binding.Args Object[] args, 
-                @Binding.MethodName String methodName,
-                @Binding.MethodDesc String methodDesc) {
-            System.out.println("atEnter, args[0]: " + args[0]);
-        }
-
-        @AtExit(inline = true)
-        public static void atExit(@Binding.Return Object returnObject) {
-            System.out.println("atExit, returnObject: " + returnObject);
-        }
-
-        @AtExceptionExit(inline = true, onException = RuntimeException.class)
-        public static void atExceptionExit(@Binding.Throwable RuntimeException ex,
-                @Binding.Field(name = "exceptionCount") int exceptionCount) {
-            System.out.println("atExceptionExit, ex: " + ex.getMessage() + ", field exceptionCount: " + exceptionCount);
-        }
-    }
-```
-
-### 2. @ExceptionHandler
-
-在上面的 `@AtEnter`配置里，生成的代码会被 try/catch 包围，那么具体的内容是在`PrintExceptionSuppressHandler`里
-
-```java
-    public static class PrintExceptionSuppressHandler {
-
-        @ExceptionHandler(inline = true)
-        public static void onSuppress(@Binding.Throwable Throwable e, @Binding.Class Object clazz) {
-            System.out.println("exception handler: " + clazz);
-            e.printStackTrace();
-        }
-    }
-```
-
-### 3. 查看反编译结果
-
-原始的Sample类是：
-
-```java
-    public static class Sample {
-        private int exceptionCount = 0;
-
-        public String hello(String str, boolean exception) {
-            if (exception) {
-                exceptionCount++;
-                throw new RuntimeException("test exception, str: " + str);
-            }
-            return "hello " + str;
-        }
-    }
-```
-
-增强后的字节码，再反编译：
-
-```java
-package com.example;
-
-public static class ByteKitDemo.Sample {
-    private int exceptionCount = 0;
-
-    public String hello(String string, boolean bl) {
-        try {
-            String string2 = "(Ljava/lang/String;Z)Ljava/lang/String;";
-            String string3 = "hello";
-            Object[] arrobject = new Object[]{string, new Boolean(bl)};
-            Class<ByteKitDemo.Sample> class_ = ByteKitDemo.Sample.class;
-            ByteKitDemo.Sample sample = this;
-            System.out.println("atEnter, args[0]: " + arrobject[0]);
-        }
-        catch (RuntimeException runtimeException) {
-            Class<ByteKitDemo.Sample> class_ = ByteKitDemo.Sample.class;
-            RuntimeException runtimeException2 = runtimeException;
-            System.out.println("exception handler: " + class_);
-            runtimeException2.printStackTrace();
-        }
-        try {
-            String string4;
-            void str;
-            void exception;
-            if (exception != false) {
-                ++this.exceptionCount;
-                throw new RuntimeException("test exception, str: " + (String)str);
-            }
-            String string5 = string4 = "hello " + (String)str;
-            System.out.println("atExit, returnObject: " + string5);
-            return string4;
-        }
-        catch (RuntimeException runtimeException) {
-            int n = this.exceptionCount;
-            RuntimeException runtimeException3 = runtimeException;
-            System.out.println("atExceptionExit, ex: " + runtimeException3.getMessage() + ", field exceptionCount: " + n);
-            throw runtimeException;
-        }
-    }
-}

- * 在这里支持配置一个 error hander ？做为插入的异常处理的
- *
- *  按名字匹配，按模糊匹配？？有没有这样子的需求？，按interface匹配，按基础类继承的匹配
- *
- *  函数的匹配，直接是名字一样，desc 一样的。 匹配有 annotation 的
- *
- *  只有 NewField 才是加新的field，原来类里有的field，就直接写上就可以了。
