@FieldDefaults was introduced as experimental feature in lombok v0.11.4.
@f.history> <@f.experimental>
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 (instance) 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 (instance) 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).
lombok.fieldDefaults.flagUsage
= [warning
| error
] (default: not set)
@FieldDefaults
as a warning or error if configured.
lombok.fieldDefautls.defaultPrivate
= [true
| false
] (default: false)
true
, every field in every class or enum anywhere in the sources being compiled will be marked as private
unless it has an explicit access modifier or the @PackagePrivate
annotation, or an explicit @FieldDefaults
annotation is present to override this config key.
lombok.fieldDefaults.defaultFinal
= [true
| false
] (default: false)
true
, every field in every class or enum anywhere in the sources being compiled will be marked as final
unless it has the @NonFinal
annotation, or an explicit @FieldDefaults
annotation is present to override this config key.
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.
