Auto Common Utilities

Overview

The Auto project has a set of common utilities to help ease use of the annotation processing environment.

Utility classes of note

• MoreTypes - utilities and Equivalence wrappers for TypeMirror and related subtypes
• MoreElements - utilities for Element and related subtypes
• SuperficialValidation - very simple scanner to ensure an Element is valid and free from distortion from upstream compilation errors
• Visibility - utilities for working with Elements' visibility levels (public, protected, etc.)
• BasicAnnotationProcessor/ProcessingStep - simple types that
  • implement a validating annotation processor
  • defer invalid elements until later
  • break processor actions into multiple steps (which may each handle different annotations)

Usage/Setup

Auto common utilities have a standard Maven setup which can also be used from Gradle, Ivy, Ant, or other systems which consume binary artifacts from the central Maven binary artifact repositories.
