protected val name : java.lang.String
Method Summary
def andFinally (body : => Unit) : Catch[T]
def apply [U >: T](body : => U) : U
Apply this catch logic to the supplied body.
def either [U >: T](body : => U) : Either[java.lang.Throwable, U]
Apply this catch logic to the supplied body, mapping the result into Either[Throwable, T] - Left(exception) if an exception was caught, Right(T) otherwise.
def opt [U >: T](body : => U) : Option[U]
Apply this catch logic to the supplied body, mapping the result into Option[T] - None if any exception was caught, Some(T) otherwise.
def or [U >: T](other : Catch[U]) : Catch[U]
def or [U >: T](pf2 : PartialFunction[U]) : Catch[U]
Create a new Catch with additional exception handling logic.
def toEither : Catch[Either[java.lang.Throwable, T]]
def toOption : Catch[Option[T]]
Convenience methods.
def withApply [U](f : (java.lang.Throwable) => U) : Catch[U]
Create a new Catch with the same isDefinedAt logic as this one, but with the supplied apply method replacing the current one.
