I am making a class in Java bytecode. I need to know how to reference fields in this object. First I need to know how to reference the "this" object as if I were accessing this.var1 from class TestClass. I know how to access fields in other objects, but not from the same object that I am executing from.
我正在用Java字节码创建一个类。我需要知道如何在这个对象中引用字段。首先，我需要知道如何引用“this”对象，就好像我正在访问它一样。从类TestClass var1。我知道如何访问其他对象中的字段，但不知道如何从我正在执行的对象中访问。

The this pointer is implicit in every method call, as a hidden first parameter. In all non-static methods, you can push it onto the stack with aload_0.
这个指针隐含在每个方法调用中，作为隐藏的第一个参数。在所有非静态方法中，您可以使用aload_0将其推到堆栈上。
More details here, or as Holger points out, in the JVM spec itself.
