DefaultMethod

```
@Documented
@Retention(RUNTIME)
@Target(PARAMETER)
public @interface DefaultMethod
```
A parameter with this annotation is assigned an instance of Method which invokes a default method implementation of this method. If such a method is not available, this annotation causes that this delegation target cannot be bound unless nullIfImpossible() is set to true. The method is declared as public and is invokable unless the instrumented type itself is not visible. Note that requesting such a method exposes the super method to reflection.

boolean cached
```
    Indicates if the instance assigned to this parameter should be stored in a static field for reuse.

```
java.lang.Class<?> targetType
```
    Specifies an explicit type that declares the default method to invoke.
    
    Returns:
