ProtocolUpgradeHandler (Vert.x Stack - Docs 5.0.0.CR3 API)

All Superinterfaces:

Handler<RoutingContext>

All Known Implementing Classes:

GraphQLWSHandler
```
public interface ProtocolUpgradeHandler
extends Handler<RoutingContext>
```
Base interface for handlers that perform protocol upgrades. Sub-interfaces hint vert.x core that we should hold the request. This allows later parsing. It can be available during the upgrade, even if there are asynchronous calls in between.
NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.
