Translator (Javassist API)

All Known Implementing Classes:

Reflection, StubGenerator
```
public interface Translator
```
An observer of Loader. The users can define a class implementing this interface and attach an instance of that class to a Loader object so that it can translate a class file when the class file is loaded into the JVM.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`void`	`onLoad(ClassPool pool, java.lang.String classname)`	Is invoked by a `Loader` for notifying that a class is loaded.
`void`	`start(ClassPool pool)`	Is invoked by a `Loader` for initialization when the object is attached to the `Loader` object.

- Method Detail
  - start
```
void start(ClassPool pool)
    throws NotFoundException,
           CannotCompileException
```
    Is invoked by a Loader for initialization when the object is attached to the Loader object. This method can be used for getting (for caching) some CtClass objects that will be accessed in onLoad() in Translator.
    
    Parameters:
    
    pool - the ClassPool that this translator should use.
    
    Throws:
    
    NotFoundException - if a CtClass cannot be found.
    
    CannotCompileException - if the initialization by this method fails.

  - onLoad
```
void onLoad(ClassPool pool,
            java.lang.String classname)
     throws NotFoundException,
            CannotCompileException
```
    Is invoked by a Loader for notifying that a class is loaded. The Loader calls
    pool.get(classname).toBytecode()
    to read the class file after onLoad() returns.
    classname may be the name of a class that has not been created yet. If so, onLoad() must create that class so that the Loader can read it after onLoad() returns.
    Parameters:
    
    pool - the ClassPool that this translator should use.
    
    classname - the name of the class being loaded.
    
    Throws:
    
    NotFoundException - if a CtClass cannot be found.
    
    CannotCompileException - if the code transformation by this method fails.
