## Interface ResourceFacade<T>

- Type Parameters:
    `T` - the type of entity that this facade should receive links for

      public interface ResourceFacade<T>

  Represents a facade for an entity which should still receive links for this entity even though this entity's instance is not available. This is useful for Collections of an entity's children (Order.comments) where the parent entity (Order) is not returned as part of the collection, but should still receive any links for the entity of type T (Comment) for whom we do not have any instance (links for "add" and "list" for example).

    Modifier and Type | Method and Description
    --- | ---
    `Class<T>` | `facadeFor()` Returns the type of entity that this facade should receive links for.
    `Map<String,? extends Object>` | `pathParameters()` Returns a map of path parameters to use to build any path to this facade's type's links.

- - ### Method Detail

    - #### facadeFor

          Class<T> facadeFor()

      Returns the type of entity that this facade should receive links for. If we represent a list of Comment entities, then that would be the type to return.

    - #### pathParameters

          Map<String,? extends Object> pathParameters()

      Returns a map of path parameters to use to build any path to this facade's type's links. If there are too many path parameter for a link, the extra ones will be ignored, but if there are not enough path parameters the link will be skipped.

      For example, when scanning a facade for a list of order comments for an order with ID "foo", you should return a map for {orderId => "foo"}, which will get you links for "/order/{orderId}/comments" ("list" and "add") but not for "/order/{orderId}/comment/{commentId}" since those need actual Comment instances ("self" and "delete").
