Abstract Value Members

  1. abstract def validate[T](implicit rds: Reads[T]): JsResult[T]

    Tries to convert the node into a JsResult[T] (Success or Error).

    Tries to convert the node into a JsResult[T] (Success or Error). An implicit Reads[T] must be defined.

Concrete Value Members

    Tries to convert the node into a T, throwing an exception if it can't.

    Tries to convert the node into a T, throwing an exception if it can't. An implicit Reads[T] must be defined.

  2. def asOpt[T](implicit fjs: Reads[T]): Option[T]

    returns

    Some[T] if it succeeds, None if it fails.

  3. def transform[A <: JsValue](rds: Reads[A]): JsResult[A]

    Transforms this node into a JsResult using provided Json transformer Reads[JsValue]
