link (Manifold :: Delegation Runtime 2026.1.6 API)

```
@Target(FIELD)
@Retention(RUNTIME)
public @interface link
```
Use @link to automatically transfer calls on unimplemented interface methods to fields in the same class.
- Choose between call forwarding and true delegation with @part
- Override linked interface methods, optionally using part classes (solves the Self problem)
- Share super interface implementations (solves the Diamond problem)
- Configure class implementation dynamically
Classes and links are many-to-many: Many of a class's interfaces may be linked to a single field. A single class may have many linked fields.
Basic usage
```
 class MyClass implements MyInterface {
   @link MyInterface myInterface; // transfers calls on MyInterface to myInterface

   public MyClass(MyInterface myInterface) {
     this.myInterface = myInterface; // dynamically configure behavior
   }
 }
 
```

Optional Element Summary

Optional Elements
Modifier and Type	Optional Element	Description
`Class<?>[]`	`share`	Where interface overlap exists with other links, this list of interfaces resolves which links to use.
`boolean`	`shareAll`	If true, indicates this link is shared where interface overlap exists with other links.
`Class<?>[]`	`value`	Specify interfaces to link.

- Element Detail
  - value
```
Class<?>[] value
```
    Specify interfaces to link. This value overrides the declared type of the field. If no interfaces are specified (default), the linked interfaces are derived from the field's declared type.
    
    Default:
    
    {}
- - share
```
Class<?>[] share
```
    Where interface overlap exists with other links, this list of interfaces resolves which links to use. Otherwise, overlapping interfaces are not linked and the class must implement them directly, or it must be declared abstract. If two or more links declare to share the same interface, a compiler error results.
    
    Default:
    
    {}
- - shareAll
```
boolean shareAll
```
    If true, indicates this link is shared where interface overlap exists with other links. Similar to share(), but includes all interfaces from this link that overlap.
    
    Default:
    
    false
