<h3>Overview</h3>
|
|
<p>
|
|
<em> NEW IN Lombok 0.10: </em> Any field can be annotated with <code>@Delegate</code> to let lombok generate delegate methods that forward the call
|
|
to this field.
|
|
</p>
|
|
<p>
|
|
Lombok delegates all <code>public</code> methods of the field's type, as well as those of its supertype except for all methods declared
|
|
in <code>java.lang.Object</code>. 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.
|
|
</p>
|
|
<p>
|
|
You can pass any number of classes into the <code>@Delegate</code> annotation. If you do that, then lombok will delegate all <code>public</code>
|
|
methods in those types (and their supertypes, except <code>java.lang.Object</code>) instead of looking at the field's type.

|
When passing classes to the annotation, these cannot contain generics. This is a limitation of java that lombok cannot work around.
|
|
</p>
|
|
<p>
|
|
When passing classes to the annotation, these classes do not need to be supertypes of the field. See the example.
