有高级字节码编辑器吗？

假设我在 Scala 中有以下内容

object Foo {
  var functions: List[String => String] = Nil // can be any type to any type.
  def addFunc(f:String => String) = functions = f :: functions
}

，在运行时，我得到了 Foo 并添加了一些函数。我现在想要构造一个新的 .class 文件，在 Scala 中实现如下所示的内容：

object MyObject { 
  def process1(s:String) = // call Foo.functions(1)
}

然后我想将 MyObject 保存在字节码中，即使 Foo 不存在，也可以稍后执行那里。

上面只是一个例子来展示我想要做什么。我的名称为 MyObject、process1，并且我必须生成一个可执行文件 MyObject.class。不需要 MyObject 的源代码（它很可能是 Java 源代码）。

因此，在较高层面上，我们需要拍摄 Foo.function(1) 的内存“快照”，将该快照转换为字节码进行存储，并生成 MyObject 的字节码使用这个。

我发现的所有字节码工程库都太低级，所以我想知道是否有一个更高级别的库可以让我处理抽象对象，例如函数等。

Suppose I have a the following in Scala

object Foo {
  var functions: List[String => String] = Nil // can be any type to any type.
  def addFunc(f:String => String) = functions = f :: functions
}

At runtime, I am given Foo with some functions added. I now want to construct a new .class file implementing something like following in Scala:

object MyObject { 
  def process1(s:String) = // call Foo.functions(1)
}

I then want to save MyObject in bytecode that can be executed later on even when Foo is not there.

The above is just an example to show what I want to do . I am given the names MyObject, process1, and I have to generate an executable file MyObject.class. The source of MyObject is not needed (it could well have been Java source).

So, at a high level, we need to take memory "snapshot" of Foo.function(1), convert that snapshot into bytecode to store, and generate bytecode of MyObject using this.

All the bytecode engineering libraries I found are too low-level, so I was wondering if there is a higher level library that lets me deal with abstract objects such as functions etc.
