Introduction

Goals

Data persistence on Android can be tricky. In our applications, we have always used handwritten SQL commands to work with the database directly since any kind of ORM for Android seemed too difficult to setup or was too slow because of reflection. So that is why we have decided to build Torch. It is easy to setup and easy to use and also really fast as it does not use reflection, but annotation processing in the compile-time.

Features

• From 0 to 60 in seconds: Adding Torch to your project is a piece of cake and there is not much you need to learn before you start using it.
• User-friendly API: We have spent many sleepless nights drafting the API to match our own high requirements to deliver an easy-to-use interface.
• Superior performance: Thanks to annotation processing which happens right when you compile your code, you won't waste your processing time on slow Java reflection. Nothing is dynamic, everything is precompiled.
• Compile time safety: Many ORM libraries let you work with fields of your entities using their names as Java strings. We believe that this is a disadvantage because you can not let the compiler help you check if you did not refactor the field away by changing its name or removing it. With Torch you will reference the fields in compile-time safe manner.
