def clone(): AnyRef

def collect[B](error: JsonValidationError)(f: PartialFunction[Float, B]): Reads[B]

def composeWith[B <: JsValue](rb: Reads[B]): Reads[Float]

Creates a new Reads, which first passes the input JSON to rb, and then it executes this Reads on the pre-processed JSON (if rb has successfully handled the input JSON).

Create a new Reads which maps the value produced by this Reads.

final def notify(): Unit

final def notifyAll(): Unit

def orElse(v: Reads[Float]): Reads[Float]

Creates a new Reads, based on this one, which first executes this Reads' logic then, if this Reads resulted in a JsError, runs the second Reads on the JsValue.

def preprocess(f: PartialFunction[JsValue, JsValue]): Reads[Float]

Creates a new Reads, which first transforms the input JSON using the given tranformer, and then it executes this Reads on the pre-processed JSON.

Convert the JsValue into a A

Widen this Reads.
