extends Object

Method Summary

Modifier and Type	Method and Description
static Throwable	getInitialCause(Throwable throwable) If throwable has a non-empty cause, returns throwable at the bottom of the stack.
static String	getThrowableOrigin(Throwable throwable) Returns string representing class, method, filename and line number that throwable was thrown from
static void	propagateIfInterrupt(Throwable thrown) Propagates an InterruptedException masquerading as another Throwable.
static <X extends Throwable> void	throwIfAnyCauseInstanceOf(Throwable throwable, Class<X> declaredType) Traverse exception chain by recursively calling getCause() and throws it if there is any exception found which is an instance of declaredType.
static <X extends Throwable> void	throwIfInitialCauseInstanceOf(Throwable throwable, Class<X> declaredType) Traverse exception chain by recursively calling getCause() and throws it if initial exception (the one at the bottom of the stack) is an instance of declaredType.

throwIfAnyCauseInstanceOf

public static <X extends Throwable> void throwIfAnyCauseInstanceOf(Throwable throwable,
                                                                   Class<X> declaredType)
                                                            throws X extends Throwable

Traverse exception chain by recursively calling getCause() and throws it if there is any exception found which is an instance of declaredType. Example usage:

   try {
     future.get()
   } catch (ExecutionException) {
     MoreThrowables.throwIfAnyCauseInstanceOf(t, BarException.class);
   }

Throws:

X extends Throwable

throwIfInitialCauseInstanceOf

public static <X extends Throwable> void throwIfInitialCauseInstanceOf(Throwable throwable,
                                                                       Class<X> declaredType)

Traverse exception chain by recursively calling getCause() and throws it if initial exception (the one at the bottom of the stack) is an instance of declaredType. Example usage:

   try {
     future.get()
   } catch (ExecutionException) {
     MoreThrowables.throwIfInitialCauseInstanceOf(t, BarException.class);
   }

Throws:
