*Generated immutable value classes for Java 7+* <br />

**Value classes** are extremely common in Java projects. These are classes for
|
|
which you want to treat any two instances with suitably equal field values as
|
|
interchangeable. That's right: we're talking about those classes where you wind
|
|
up implementing `equals`, `hashCode` and `toString` in a bloated, repetitive,
|
|
formulaic yet error-prone fashion.
|
|
|
|
Writing these methods the first time is not too bad, with the aid of a few
|
|
helper methods and IDE templates. But once written they continue to burden
|
|
reviewers, editors and future readers. Their wide expanses of boilerplate
|
|
sharply decrease the signal-to-noise ratio of your code... and they love to
|
|
harbor hard-to-spot bugs.
|
|
|
|
AutoValue provides an easier way to create immutable value classes, with a lot
|
|
less code and less room for error, while **not restricting your freedom** to
|
|
code almost any aspect of your class exactly the way you want it.
