Method Details

demand

public void demand(Runnable demandCallback)

Description copied from interface: Request

Specified by:

demand in interface org.eclipse.jetty.io.Content.Source

Specified by:

demand in interface Request

Overrides:

demand in class Request.Wrapper

Parameters:

demandCallback - the demand callback to invoke when there is a content chunk available.

See Also:

• Content.Source.demand(Runnable)

addIdleTimeoutListener

public void addIdleTimeoutListener(Predicate<TimeoutException> onIdleTimeout)

Description copied from interface: Request

Adds a listener for idle timeouts.

The listener is a predicate function that should return true to indicate that the idle timeout should be handled by the container as a fatal failure (see Request.addFailureListener(Consumer)); or false to ignore that specific timeout and for another timeout to occur after another idle period.

Idle timeout listeners are only invoked if there are no pending Request.demand(Runnable) or Response.write(boolean, ByteBuffer, Callback) operations.

Listeners are processed in the same order they are added, and the first that returns true stops the processing of subsequent listeners, which are therefore not invoked.

Specified by:

addIdleTimeoutListener in interface Request

Overrides:

addIdleTimeoutListener in class Request.Wrapper

Parameters:

onIdleTimeout - the idle timeout listener as a predicate function

See Also:

• Request.addFailureListener(Consumer)

addFailureListener

public void addFailureListener(Consumer<Throwable> onFailure)

Description copied from interface: Request

Adds a listener for asynchronous fatal failures.

When a listener is called, the effects of the failure have already taken place:

• Pending Request.demand(Runnable) have been woken up.
• Calls to Request.read() will return the Throwable failure.
• Pending and new Response.write(boolean, ByteBuffer, Callback) calls will be failed by calling Callback.failed(Throwable) on the callback passed to Response.write(boolean, ByteBuffer, Callback).

Listeners are processed in the same order they are added.

Specified by:

addFailureListener in interface Request

Overrides:

addFailureListener in class Request.Wrapper

Parameters:

onFailure - the failure listener as a consumer function

See Also:

• Request.addIdleTimeoutListener(Predicate)

getContext

public Context getContext()

Description copied from interface: Request

Get the Context associated with this Request.

Note that a Request should always have an associated Context since if the Request is not being handled by a ContextHandler then the Context from Server.getContext() will be used.

Specified by:

getContext in interface Request

Overrides:

getContext in class Request.Wrapper

Returns:

the Context associated with this Request. Never null.

• ContextHandler
• Server.getContext()
