摘　　要：在基于语言考虑代码安全性的工作中,往往需要将高级语言程序翻译成类型化低级语言的程序进行类型检查.许多高级语言具有类型调度结构,在向低级语言的编译过程中需要用标签机制来实现.针对具有多继承接口的 Java 程序包含的一种特殊的类型调度结构,提出了一种新的标签类型.包含这种标签类型的低级语言能够有效地实现 Java 程序中的接口调用.这种对接口调用的编译方法被用在一个以类型化低级语言为验证语言的 Java 字节码即时编译器中.In the area of language -based security, programs written in typed high-level languages need to be translated into those written in typed low-level languages. This work is not trivial when type dispatch constructs are involved and implemented with tag mechanism. This paper proposes a new type that can deal with a special type dispatch construct occurring in the interface invokation of Java. A low-level language with this type is able to efficiently implement the interface invokation. This implementation approach is adopted in a Just-In-Time compiler with a typed low-level language as a certifying language.
