* Links an attribute to the the results of an entity available in a {@link com.univocity.parsers.common.Results} instance.
* Regular attributes of any type are allowed if the results associated are expected to contain a single value. If there
* are multiple results the annotated attribute can be declared as an array or a collection type.
* If linking to a {@link java.util.Map}, you must add the {@link Group} annotation to the attribute to configure how the
* keys should be populated. The configuration in this {@code Linked} annotation will be used to populate the values of the map.

public @interface Linked {
* The name of the entity in the {@link com.univocity.parsers.common.Results} instance whose rows will be read
* to generate instances of the given {@link #type()}. If empty, the name of the attribute will be used as the

* @return name of the entity whose results should be linked to the parent instance.
String entity() default "";
* The type of object that should be created for each {@link com.univocity.parsers.common.Result} associated with
* the given {@link #entity()} name. Defaults to the actual attribute type. A type must be provided explicitly if
* the attribute is a collection.
* @return the type to be instantiated for each row linked to the parent instance.
Class type() default Object.class;
* Provides the type of the collection to be instantiated for this linked attribute (if applicable). The following
* defaults apply if the type of this attribute is not a concrete type:
* <ul>
* <li>Attribute of type {@link java.util.Set} or {@link java.util.Collection} initialized with a new {@link java.util.HashSet}</li>
* <li>Attribute of type {@link java.util.List} initialized with a new {@link java.util.ArrayList}</li>
* </ul>
* @return the concrete collection type to create for storing linked results of the given {@link #type()}
Class container() default Object.class;
