sealed trait Retry[+T] extends AnyRef

The Retry type represents a computation that is retrying itself in case of an exception. It uses a RetryStrategy as a policy for the retry operation.

The result may be successful consisting of the computation result value or a failure that is wrapping the underlying exception. The type is similar to the scala scala.util.Try type.

Example:

import scala.concurrent.duration._
import util.retry.blocking.{RetryStrategy, Failure, Retry, Success}

implicit val retryStrategy =
 RetryStrategy.fixedBackOff(retryDuration = 1.seconds, maxAttempts = 2)

val r = Retry(1 / 1) match {
  case Success(x) => x
  case Failure(t) => log("Exception occurred", t)
}

Abstract Value Members

  1. abstract def flatMap[S](f: (T) ⇒ Retry[S]): Retry[S]

    Permalink

    Returns true if the Retry is a Failure otherwise it returns false.

  2. abstract def foreach[X](f: (T) ⇒ X): Unit

    Permalink

    Applies the given function f if this is a Success, otherwise returns Unit if this is a Failure.

  3. abstract def get: T

    Permalink

    Returns the computation value in case of a Success.

    Returns the computation value in case of a Success. In case of a Failure it throws the underlying exception.

  4. abstract def isFailure: Boolean

    Permalink

    Returns true if the Retry is a Failure otherwise it returns false.

  5. abstract def isSuccess: Boolean

    Permalink

    Returns true if the Retry is a Success otherwise it returns false otherwise.

  6. abstract def map[S](f: (T) ⇒ S)(implicit strategy: RetryStrategy): Retry[S]

    Permalink

    Maps the given function to the value from this Success or returns this if this is a Failure.

  7. abstract def recover[X >: T](f: PartialFunction[Throwable, X]): Retry[X]

    Permalink

    Applies the given function f if this is a Failure, otherwise returns this if this is a Success.

  8. abstract def transform[X](f: (T) ⇒ X): X

    Permalink

    Transforms the Retry value by applying a transformation function to its underlying value
