@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). +

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. +
