Question

What are the common standard exceptions in Scala? I am especially interested in how is .Net's NotImplementedException equivalent called?

UPDATE: The answer about the NotImplementedException seems to be org.apache.commons.lang.NotImplementedException

Était-ce utile?

La solution

Almost nothing:

package scala {
  final class MatchError(obj: Any) extends RuntimeException
  final class UninitializedError extends RuntimeException("uninitialized value")
  final case class UninitializedFieldError (msg: String) extends RuntimeException(msg)

  package util.regex {
    class SyntaxError(e: String) extends RuntimeException(e)
  }

  package xml {

    class BrokenException() extends java.lang.Exception
    case class MalformedAttributeException(msg: String) extends RuntimeException(msg)

    package dtd {
      case class ValidationException(e: String) extends Exception(e)
    }

    package include {
      class CircularIncludeException(message: String) extends XIncludeException
      class UnavailableResourceException(message: String) extends XIncludeException(message)
      class XIncludeException(message: String) extends Exception(message)
    }

    package parsing {
      case class FatalError(msg: String) extends java.lang.RuntimeException(msg)
    }
  }
}

The rest comes from Java, which cover pretty much all corners. It begs the question of what these Scala methods throw on other platforms, doesn't it?

Autres conseils

The NotImplementedException is currently being considered for Scala 2.10, probably. See this thread.

You can just use whatever default already exists in Java. Scala doesn't really add anything to the standard exceptions in Java.
