Class ExceptionEvaluator

java.lang.Object

com.mastfrog.acteur.errors.ExceptionEvaluator

All Implemented Interfaces:

Comparable<ExceptionEvaluator>

@Singleton
public abstract class ExceptionEvaluator
extends Object
implements Comparable<ExceptionEvaluator>

Converts exceptions thrown inside Acteurs into error messages. Multiple ones can be registered. To register, simply bind your implementation as an eager singleton in your Guice module.

Note that this class does not suppress logging of exceptions - to do that, implement an ErrorHandler and bind it as an eager singleton. This simply decides how to convert a particular exception into an HTTP response.
