  39. def read[T](t: T): Reads[T]

    Pure Reads doesn't read anything but creates a JsObject based on JsPath with the given T value

  40. def read[T](implicit r: Reads[T]): Reads[T]

    Reads a T at JsPath

  41. def readNullable[T](implicit r: Reads[T]): Reads[Option[T]]

    Reads a Option[T] search optional or nullable field at JsPath (field not found or null is None and other cases are Error).

    Reads a Option[T] search optional or nullable field at JsPath (field not found or null is None and other cases are Error).

    It runs through JsValue following all JsPath nodes on JsValue except last node: - If one node in JsPath is not found before last node => returns JsError( "missing-path" ) - If all nodes are found till last node, it runs through JsValue with last node =>

    • If last node is not found => returns None
    • If last node is found with value "null" => returns None
    • If last node is found => applies implicit Reads[T]
