java Generic Parsing (03): Virtual machine Execution Generic codeA Java Virtual machine does not have a generic type object, all objects belong to the normal class, even in the early version of the generic implementation, A program that uses generics can be compiled into a class file that can run on a 1.0 virtual machine, and this backward compatibility is discar
Preface
At the end of the article "Code Runaway and state machine", we left a "job" that resolves the "Member access expression", so we can do this work together.
First of all, why do you want to write a parser that looks useless? Because in some IOC or AOP container (unfortunately I need to implement an IOC container), it is often necessary to dynamically solve the value of a member access expression, and
This problem occurs recently when an android application is used. The customer requires that the function be registered before it can be used, and the program itself is not used online. Therefore, the machine code registration mechanism should be added to the program.
It is well known that android applications are developed based on Java. If no processing is performed, you can directly decompile the APK to
