Overview

+

+ NEW IN Lombok 0.10: Any field can be annotated with @Delegate to let lombok generate delegate methods that forward the call + to this field. +

+

+ Lombok delegates all public methods of the field's type, as well as those of its supertype except for all methods declared + in java.lang.Object. You can provide a specific implementation for a method by providing you own implementation, lombok will not + generate delegate methods for those already declared in the class. +

+

+ You can pass any number of classes into the @Delegate annotation. If you do that, then lombok will delegate all public + methods in those types (and their supertypes, except java.lang.Object) instead of looking at the field's type. +

+
+
+
+

With Lombok

+
@HTML_PRE@
+
+
+
+

Vanilla Java

+
@HTML_POST@
+
+
+
+
+

Small print

+

+ When passing classes to the annotation, these cannot contain generics. This is a limitation of java that lombok cannot work around. +

+

+ When passing classes to the annotation, these classes do not need to be supertypes of the field. See the example. +
