The Rhino code base reads almost like C code: it avoids allocation and does as much as possible with jump tables to avoid the overhead of virtual method lookups.
Rhino代码读起来很像C程序：它避免过多的分配，并且尽量多地使用跳转表（Jump Tables）来避免虚方法查询（Virtual Method Lookups）的额外开支。
Of course, if the class hierarchy changes and a second target method becomes possible, then the JIT compiler can correct the originally generated code so that the virtual invocation is performed.
当然，如果类层次结构发生变化，并且出现另外的目标方法，则JIT编译器可以更正最初生成的代码以便执行虚调用。
