Jonty

A simple Kotlin/Java annotation processor to generate a list of a class field names.

For example:

@Fieldable
public class User {
    private final List<Profile> profiles;
    private final String username;
    private final String password;
    private final Date lastLogin;
    
    // etc...
}

Jonty will generate an object in a Kotlin file in the User class' package:

object User_JontyFielder {
  @JvmField
  val FIELDS: Iterable<String> = setOf("profiles", "username", "password", "lastLogin")
}

Which can be accessed via:

val fields = User_JontyFielder.FIELDS

or

Iterable<String> fields = User_JontyFielder.FIELDS

Usage

Just annotate your Java/Kotlin class with the @Fieldable annotation and Jonty will generate a class based upon your class name.

There are no restrictions on class or field access modifiers.

If the class is a child class, then the unique field names for all parent classes will also be added.

Static fields are ignored.

Download

Available via Jitpack.

For Gradle, add kapt3 plugin:

apply plugin: 'kotlin-kapt'

Add to your Jitpack to your project repository configuration"

maven { url "https://jitpack.io" }

Add these dependencies:

compileOnly "com.github.peter-tackage.jonty:jonty:<latest-version>"
kapt "com.github.peter-tackage.jonty:jonty-processor:<latest-version>"

See freesound-android for a full working example.

Why Jonty?

Because of the fielding (terrible pun, I know) done here.

Development

To locally test changes to Jonty, use the example-local module, which imports the module directly, rather than going through Jitpack.

To do this, uncomment this line in settings.gradle -

// Uncomment to test locally.
//include 'example-local'
