location is two-way thing.
Given @location(“/a/{id}/b”) class Foo(val id : Int, val optional : String = “default")
On the routing side, when you use it like get<Foo> { it.id } it creates routing entry with “/a/{id}/b” path, much like route(“/a/{id}/b”) and when routing is executed, it binds path variable id and query variable optional and creates instance of Foo. It then passes it into the lambda.
On the other side, you can get URI for existing instance of Foo, so that given Foo(1, “yes”) you will get /a/1/b?optional=yes URI.
