class ExceptionManager extends AnyRef

A class to register com.twitter.finatra.http.exceptions.ExceptionMappers and handle exceptions.

Given an exception, the ExceptionManager will find an com.twitter.finatra.http.exceptions.ExceptionMapper to handle that particular class of exceptions. If the mapper for that exception isn't registered, the ExceptionManager will try the exception's parent class, and so on, until it reaches the Throwable class. The framework registers a "root" exception mapper over Throwable which will eventually be invoked. Users are free to register their own ExceptionMapper[Throwable] which overrides the "root" exception mapper.
