Class CodeTransProcessor

java.lang.Object

javax.annotation.processing.AbstractProcessor

io.vertx.codetrans.CodeTransProcessor

All Implemented Interfaces:

Processor

public class CodeTransProcessor
extends AbstractProcessor

A processor plugin generate scripts from Verticle class. It scans all the compiled classes and tries to generate corresponding scripts for each class.

The script is named after the verticle fqn using the last atom of the package name and the lower cased class name, for example : examples.http.Server maps to http/server.js, http/server.groovy, etc...

The processor is only active when the option codetrans.output is set to a valid directory where the scripts will be written. A log codetrans.log will also be written with the processor activity.

The processor can be configured using the condetrans.config property targeting a JSON file. The JSON file contains a set of exclusions and is structured as follows:

     {
       "excludes": [
        {
          "package" : "the (java) package to exclude",
          "langs" : ["lang1", "lang2"]
        }
       ]
     }
 

The package element is mandatory. Langs is optional. When not set, all languages are skipped. Languages are identified by their extensions.
