Constructor Details

AbstractRequestContextBuilder

protected AbstractRequestContextBuilder(boolean server,
 HttpRequest req)

Creates a new builder with the specified HttpRequest.

Parameters:

server - whether this builder will build a server-side context.

req - the HttpRequest.

AbstractRequestContextBuilder

protected AbstractRequestContextBuilder(boolean server,
 RpcRequest rpcReq,
 URI uri)

Creates a new builder with the specified RpcRequest and URI.

Parameters:

server - whether this builder will build a server-side context.

rpcReq - the RpcRequest.

uri - the URI of the request endpoint.

Method Details

meterRegistry

protected final MeterRegistry meterRegistry()

Returns the MeterRegistry.

meterRegistry

public AbstractRequestContextBuilder meterRegistry(MeterRegistry meterRegistry)

Sets the MeterRegistry. If not set, NoopMeterRegistry is used.

eventLoop

protected final EventLoop eventLoop()

Returns the EventLoop that handles the request.

eventLoop

public AbstractRequestContextBuilder eventLoop(EventLoop eventLoop)

Sets the EventLoop that handles the request. If not set, one of the CommonPools.workerGroup() is used.

alloc

protected final ByteBufAllocator alloc()

Returns the ByteBufAllocator.

alloc

public AbstractRequestContextBuilder alloc(ByteBufAllocator alloc)

Sets the ByteBufAllocator. If not set, ByteBufAllocator.DEFAULT is used.

request

@Nullable
protected final @Nullable HttpRequest request()

Returns the HttpRequest of the context.

rpcRequest

@Nullable
protected final @Nullable RpcRequest rpcRequest()

Returns the RpcRequest of the context.

sessionProtocol

protected final SessionProtocol sessionProtocol()

Returns the SessionProtocol of the request.

sessionProtocol

public AbstractRequestContextBuilder sessionProtocol(SessionProtocol sessionProtocol)

Sets the SessionProtocol of the request.

Throws:

IllegalArgumentException - if the specified SessionProtocol is not compatible with the scheme of the URI you specified when creating this builder. For example, you cannot specify SessionProtocol.H2C if you created this builder with h1c://example.com/.

remoteAddress

protected final SocketAddress remoteAddress()

Returns the remote socket address of the connection.

remoteAddress

public AbstractRequestContextBuilder remoteAddress(SocketAddress remoteAddress)

Sets the remote socket address of the connection. If not set, it is auto-generated with the localhost IP address (e.g. "127.0.0.1" or "::1").

localAddress

protected final SocketAddress localAddress()

Returns the local socket address of the connection.

localAddress

public AbstractRequestContextBuilder localAddress(SocketAddress localAddress)

Sets the local socket address of the connection. If not set, it is auto-generated with the localhost IP address (e.g. "127.0.0.1" or "::1").

sslSession

@Nullable
protected final @Nullable SSLSession sslSession()

Returns the SSLSession of the connection.

Returns:

the SSLSession, or null if the SessionProtocol is not TLS.

sslSession

public AbstractRequestContextBuilder sslSession(SSLSession sslSession)

Sets the SSLSession of the connection. If the current SessionProtocol is not TLS, the TLS version of the current SessionProtocol will be set automatically. For example, SessionProtocol.H2C will be automatically upgraded to SessionProtocol.H2. Note that upgrading the current SessionProtocol may trigger an IllegalArgumentException, as described in sessionProtocol(SessionProtocol).

isRequestStartTimeSet

protected final boolean isRequestStartTimeSet()

Returns whether the request start time has been specified. If not specified, the builder will use the current time returned by requestStartTimeNanos() and requestStartTimeMicros() as the request start time.

requestStartTimeNanos

protected final long requestStartTimeNanos()

Returns the System.nanoTime() value when the request started.

Throws:

IllegalStateException - if the request start time is unspecified.

requestStartTimeMicros

protected final long requestStartTimeMicros()

Returns the number of microseconds since the epoch when the request started.

Throws:

IllegalStateException - if the request start time is unspecified.

requestStartTime

public AbstractRequestContextBuilder requestStartTime(long requestStartTimeNanos,
 long requestStartTimeMicros)

Sets the request start time of the request.

Parameters:

requestStartTimeNanos - the System.nanoTime() value when the request started.

requestStartTimeMicros - the number of microseconds since the epoch when the request started.

method

protected final HttpMethod method()

Returns the HttpMethod of the request.

method

protected AbstractRequestContextBuilder method(HttpMethod method)

Sets the HttpMethod of the request.

Throws:

IllegalArgumentException - if the specified HttpMethod is not same with the HttpMethod of the HttpRequest you specified when creating this builder. This exception is not thrown if you created a builder with an RpcRequest.

authority

protected final String authority()

Returns the authority of the request.

requestTarget

protected final RequestTarget requestTarget()

Returns the RequestTarget.

id

public AbstractRequestContextBuilder id(RequestId id)

Sets the RequestId. If not set, a random RequestId is generated with RequestId.random().

id

protected final RequestId id()

Returns the RequestId.

fakeChannel

protected final Channel fakeChannel()

Returns a fake Channel which is required internally when creating a context.

timedOut

protected final boolean timedOut()

Returns whether a timeout is set.

timedOut

public AbstractRequestContextBuilder timedOut(boolean timedOut)

Sets the specified timedOut. If the specified timedOut is true, RequestContext.isTimedOut() will always return true. This is useful for checking the behavior of a Service and Client when a request exceeds a deadline.
