      java.lang.Exception
          java.lang.RuntimeException
              edu.rice.cs.plt.lambda.WrappedException

All Implemented Interfaces:

Serializable

public class WrappedException
extends RuntimeException

A wrapper for checked exceptions, allowing them to be thrown by lambda code (and in other situations in which an interface does not allow checked exceptions to be thrown).

Clients should check for the expected exception type with code like the following:

 try { ... }
 catch (WrappedException e) { 
   if (e.getCause() instanceof SomeCheckedException) { throw (SomeCheckedException) e.getCause(); }
   else { throw e; }
 }
 

Unfortunately, the Java language does not allow abstraction over exception types — a method cannot be declared to throw a variable type — so a generic version of the above block of code cannot be included as a method here.
