## Interface IOEventHandler

- All Known Subinterfaces:
    HttpConnectionEventHandler
  All Known Implementing Classes:
    ClientH2IOEventHandler, ClientHttp1IOEventHandler, ClientHttpProtocolNegotiator, H2OnlyClientProtocolNegotiator, H2OnlyServerHttpProtocolNegotiator, ServerH2IOEventHandler, ServerHttp1IOEventHandler, ServerHttpProtocolNegotiator

      @Internal
      public interface IOEventHandler

  IOEventHandler interface is used by I/O reactors to handle I/O events for individual I/O sessions. All methods of this interface are executed on a single dispatch thread of the I/O reactor. Therefore, it is important that event processing does not not block the I/O dispatch thread for too long, thus making the I/O reactor unable to react to other events.
  Since:
    5.0
