Method Detail

assist

CompileTimeClass[] assist(ClassPool cp,
                          java.lang.String importname,
                          java.lang.String[] args)
                          throws CannotCompileException

Is called when the Javassist preprocessor encounters an import declaration annotated with the "by" keyword.

The original import declaration is replaced with new import declarations of classes returned by this method. For example, the following implementation does not change the original declaration:

 public CtClass[] assist(ClassPool cp, String importname, String[] args) {
     return new CtClass[] { cp.get(importname) };
 }
 

Parameters:

cp - class pool

importname - the class imported by the declaration

args - the parameters specified by the annotation

Returns:

the classes imported in the java source program produced by the preprocessor.

Throws:

CannotCompileException
