@Deprecated public static <R extends RuntimeException> R propagate(Throwable throwable, Function<Throwable,R> function)
throwable as-is if it is an instance of
RuntimeException or Error, or else as a
last resort, wraps it in a RuntimeException provided by the
function and then propagates.
This method always throws an exception. The RuntimeException return
type is only for client code to make Java type system happy in case a
return value is required by the enclosing method. Example usage:
T doSomething() {
try {
return someMethodThatCouldThrowAnything();
} catch (IKnowWhatToDoWithThisException e) {
return handle(e);
} catch (Throwable t) {
throw Throwables.propagate(t, new Function<MyRuntimeException>() {
public MyRuntimeException apply(Throwable t) {
return new MyRuntimeException(t);
}
});
}

throwable as-is if it is an instance of
RuntimeException or Error, or else as a
last resort, wraps it in the RuntimeException specified by the
runtimeType parameter provided and then propagates.
This method always throws an exception. The RuntimeException return
type is only for client code to make Java type system happy in case a
return value is required by the enclosing method.
The runtime type passed as a parameter must be a runtime exception with a
constructor taking a single Throwable as an argument accessible via
reflection. If this is not the case an appropriate exception (
NoSuchMethodException, InstantiationException,
IllegalAccessException, InvocationTargetException) will be
thrown wrapped in a simple RuntimeException. If you can't make your
exception match those criteria, you might want to look at using
propagate(Throwable, Function).
Example usage:
T doSomething() {
try {
return someMethodThatCouldThrowAnything();
} catch (IKnowWhatToDoWithThisException e) {
return handle(e);
} catch (Throwable t) {
throw Throwables.propagate(t, MyRuntimeException.class);
}
}
