Super types of the parameter type are also allowed.
The instance parameter is only used if the field is not static.

Type Parameters:

I - The invoker interface type

Parameters:

invokerClass - The invoker interface class

instance - The instance of the class the field is in

field - The field to get

Returns:

The setter instance

makeDynamicSetter

public static <I> I makeDynamicSetter(@Nonnull
                                      java.lang.Class<I> invokerClass,
                                      @Nonnull
                                      java.lang.reflect.Field field)
