AutoValue: Ignore Hash Equals Extension

An extension for Google's AutoValue that omits @IgnoreHashEquals field values from hashCode() and equals().

Basic Usage

Include the extension in your project, define an @IgnoreHashEquals annotation, and apply it to any fields that you wish to be ignored from the generated hashCode and equals implementation.

@Retention(SOURCE) @Target({
METHOD, PARAMETER, FIELD
}
) public @interface IgnoreHashEquals {
 
}

@AutoValue public abstract class User {

public abstract String id();

@IgnoreHashEquals public abstract String name();
 
}

When you call hashCode() or equals() any properties with @IgnoreHashEquals will be ignored from the calculation.

@IncludeHashEquals Usage

Include the extension in your project, define an @IncludeHashEquals annotation, and apply it to any fields that you wish to be included from the generated hashCode and equals implementation.

@Retention(SOURCE) @Target({
METHOD, PARAMETER, FIELD
}
) public @interface IncludeHashEquals {
 
}

@AutoValue public abstract class User {

@IncludeHashEquals public abstract String id();

public abstract String name();
 
}

When you call hashCode() or equals() any properties without @IncludeHashEquals will be ignored from the calculation.
