@FieldDefaults

New default field modifiers for the 21st century.

Since

@FieldDefaults was introduced as experimental feature in lombok v0.11.4.

Experimental

Experimental because:

New feature; unsure if this busts enough boilerplate
Would be nice if you could stick this on the package-info.java package to set the default for all classes in that package
Part of the work on @Value, which is experimental

Current status: positive - Currently we feel this feature may move out of experimental status with no or minor changes soon.

Overview

The @FieldDefaults annotation can add an access modifier (public, private, or protected) to each field in the annotated class or enum. It can also add final to each field in the annotated class or enum.

To add final to each field, use @FieldDefaults(makeFinal=true). Any non-final field which must remain nonfinal can be annotated with @NonFinal (also in the lombok.experimental package).

To add an access modifier to each field, use @FieldDefaults(level=AccessLevel.PRIVATE). Any field that does not already have an access modifier (i.e. any field that looks like package private access) is changed to have the appropriate access modifier. Any package private field which must remain package private can be annotated with @PackagePrivate (also in the lombok.experimental package).

Vanilla Java

@HTML_POST@

Small print

Like other lombok handlers that touch fields, any field whose name starts with a dollar ($) symbol is skipped entirely. Such a field will not be modified at all.
