Class ErrorHandler

java.lang.Object

io.vertx.reactivex.ext.web.handler.ErrorHandler

All Implemented Interfaces:

Handler<RoutingContext>, io.vertx.lang.rx.RxDelegate

public class ErrorHandler
extends Object
implements io.vertx.lang.rx.RxDelegate, Handler<RoutingContext>

A pretty error handler for rendering error pages. When working in development mode exception details will be returned in the server responses, otherwise or when manually specified no exception details are returned in the HTTP response. The reason the display of the exception details is by default dependent of the mode is to follow the security best practices: https://www.owasp.org/index.php/Improper_Error_Handling

NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
