Jeta - is an Open Source framework, built on the top of javax.annotation.processing, that brings metaprogramming into Java Project. It aims to reduce boilerplate code and increase errors detection at compile-time.

Metaprogramming is achieved by code generating which makes programs fast and stable at runtime. The main goal is to ensure that if the metacode is compiled, it will work correctly. Jeta is also designed to provide rapid code.

If you are dissatisfied with Java Reflection, welcome aboard :)

At a glance:

Even though Jeta is made to help Java developers to write source code generators, it also provides a number of features, built on the same foundation. Let’s take a look on a simple example:

@Log

Whatever logging tool is used in your project, the loggers can be supplied into classes through Log annotation. By default the logger has a name of the host (master) class:

class LogSample {
    @Log
    Logger logger;
}

instead of:

class LogSample {
    private final Logger logger = LoggerFactory.getLogger(LogSample.class);
}

The second approach implies copy-paste. Programmers often forget to replace the class, so loggers have incorrect names. In the first code snippet, there’s no need to copy the logger code - it’s easy to write, but even if you do, the logger will have the correct name.

Of course, this is a straightforward sample, but it illustrates what Jeta is all about - less code, more stability. Follow the user’s guide to find more features and know how to create yours.
