Method Detail

newDerivedContext

public ServiceRequestContext newDerivedContext()

Description copied from interface: RequestContext

Creates a new derived RequestContext which only the RequestLog is different from the deriving context. Note that the references of Attributes in the RequestContext.attrs() are copied as well.

Specified by:

newDerivedContext in interface RequestContext

Specified by:

newDerivedContext in interface ServiceRequestContext

newDerivedContext

public ServiceRequestContext newDerivedContext(Request request)

Description copied from interface: RequestContext

Creates a new derived RequestContext with the specified Request which the RequestLog is different from the deriving context. Note that the references of Attributes in the RequestContext.attrs() are copied as well.

Specified by:

newDerivedContext in interface RequestContext

Specified by:

newDerivedContext in interface ServiceRequestContext

channel

protected Channel channel()

Description copied from class: NonWrappingRequestContext

Returns the Channel that is handling this request, or null if the connection is not established yet.

Specified by:

channel in class NonWrappingRequestContext

server

public Server server()

Description copied from interface: ServiceRequestContext

Returns the Server that is handling the current Request.

Specified by:

server in interface ServiceRequestContext

virtualHost

public VirtualHost virtualHost()

Description copied from interface: ServiceRequestContext

Returns the VirtualHost that is handling the current Request.

Specified by:

virtualHost in interface ServiceRequestContext

pathMapping

public PathMapping pathMapping()

Description copied from interface: ServiceRequestContext

Returns the PathMapping associated with the Service that is handling the current Request.

Specified by:

pathMapping in interface ServiceRequestContext

pathMappingContext

public PathMappingContext pathMappingContext()

Description copied from interface: ServiceRequestContext

Returns the PathMappingContext used to find the Service.

Specified by:

pathMappingContext in interface ServiceRequestContext

pathParams

public Map<String,String> pathParams()

Description copied from interface: ServiceRequestContext

Returns the path parameters mapped by the PathMapping associated with the Service that is handling the current Request.

Specified by:

pathParams in interface ServiceRequestContext

service

public <T extends Service<HttpRequest,HttpResponse>> T service()

Description copied from interface: ServiceRequestContext

Returns the Service that is handling the current Request.

Specified by:

service in interface ServiceRequestContext

blockingTaskExecutor

public ExecutorService blockingTaskExecutor()

Description copied from interface: ServiceRequestContext

Returns the ExecutorService that could be used for executing a potentially long-running task. The ExecutorService will propagate the ServiceRequestContext automatically when running a task.

Note that performing a long-running task in Service.serve(ServiceRequestContext, Request) may block the Server's I/O event loop and thus should be executed in other threads.

Specified by:

blockingTaskExecutor in interface ServiceRequestContext

mappedPath

public String mappedPath()

Description copied from interface: ServiceRequestContext

Returns the path with its context path removed. This method can be useful for a reusable service bound at various path prefixes.

Specified by:

mappedPath in interface ServiceRequestContext

negotiatedProduceType

@Nullable
public MediaType negotiatedProduceType()

Description copied from interface: ServiceRequestContext

Returns the negotiated producible media type. If the media type negotiation is not used for the Service, null would be returned.

Specified by:

negotiatedProduceType in interface ServiceRequestContext

eventLoop

public EventLoop eventLoop()

Description copied from interface: RequestContext

Returns the EventLoop that is handling the current Request.

Specified by:

eventLoop in interface RequestContext

logger

public Logger logger()

Description copied from interface: ServiceRequestContext

Returns the Logger of the Service.

Specified by:

logger in interface ServiceRequestContext

sslSession

@Nullable
public SSLSession sslSession()

Description copied from interface: RequestContext

The SSLSession for this request if the connection is made over TLS, or null if the connection is not established yet or the connection is not a TLS connection.

Specified by:

sslSession in interface RequestContext

Overrides:

sslSession in class NonWrappingRequestContext

requestTimeoutMillis

public long requestTimeoutMillis()

Description copied from interface: ServiceRequestContext

Returns the amount of time allowed until receiving the current Request completely. This value is initially set from ServerConfig.defaultRequestTimeoutMillis().

Specified by:

requestTimeoutMillis in interface ServiceRequestContext

setRequestTimeoutMillis

public void setRequestTimeoutMillis(long requestTimeoutMillis)

Description copied from interface: ServiceRequestContext

Sets the amount of time allowed until receiving the current Request completely. This value is initially set from ServerConfig.defaultRequestTimeoutMillis().

Specified by:

setRequestTimeoutMillis in interface ServiceRequestContext

setRequestTimeout

public void setRequestTimeout(Duration requestTimeout)

Description copied from interface: ServiceRequestContext

Sets the amount of time allowed until receiving the current Request completely. This value is initially set from ServerConfig.defaultRequestTimeoutMillis().

Specified by:

setRequestTimeout in interface ServiceRequestContext

requestTimeoutHandler

@Nullable
public Runnable requestTimeoutHandler()

setRequestTimeoutHandler

public void setRequestTimeoutHandler(Runnable requestTimeoutHandler)

Description copied from interface: ServiceRequestContext

Sets a handler to run when the request times out. requestTimeoutHandler must close the response, e.g., by calling StreamWriter.close(). If not set, the response will be closed with HttpStatus.SERVICE_UNAVAILABLE.

For example,

   HttpResponseWriter res = HttpResponse.streaming();
   ctx.setRequestTimeoutHandler(() -> {
      res.write(HttpHeaders.of(HttpStatus.OK, MediaType.PLAIN_TEXT_UTF_8, "Request timed out."));
      res.close();
   });
   ...
 

Specified by:

setRequestTimeoutHandler in interface ServiceRequestContext

Returns the maximum length of the current Request. This value is initially set from ServerConfig.defaultMaxRequestLength(). If 0, there is no limit on the request size.

Specified by:

maxRequestLength in interface ServiceRequestContext

See Also:

ContentTooLargeException

setMaxRequestLength

public void setMaxRequestLength(long maxRequestLength)

Description copied from interface: ServiceRequestContext

Sets the maximum length of the current Request. This value is initially set from ServerConfig.defaultMaxRequestLength(). If 0, there is no limit on the request size.
