send

public ContentResponse send()
                     throws java.lang.InterruptedException,
                            java.util.concurrent.TimeoutException,
                            java.util.concurrent.ExecutionException

Description copied from interface: Request

Sends this request and returns the response.

This method should be used when a simple blocking semantic is needed, and when it is known that the response content can be buffered without exceeding memory constraints.

For example, this method is not appropriate to download big files from a server; consider using Request.send(Response.CompleteListener) instead, passing your own Response.Listener or a utility listener such as InputStreamResponseListener.

The method returns when the complete event is fired.

Specified by:

send in interface Request

Returns:

a ContentResponse for this request

Throws:

java.lang.InterruptedException - if send thread is interrupted

java.util.concurrent.TimeoutException - if send times out

java.util.concurrent.ExecutionException - if execution fails

See Also:

Response.CompleteListener.onComplete(Result)

send

public void send(Response.CompleteListener listener)

Description copied from interface: Request

Sends this request and asynchronously notifies the given listener for response events.

This method should be used when the application needs to be notified of the various response events as they happen, or when the application needs to efficiently manage the response content.

The listener passed to this method may implement not only Response.CompleteListener but also other response listener interfaces, and all the events implemented will be notified. This allows application code to write a single listener class to handle all relevant events.

Specified by:

send in interface Request

Parameters:

listener - the listener that receives response events

getResponseListeners

protected java.util.List<Response.ResponseListener> getResponseListeners()

getPushListener

public java.util.function.BiFunction<Request,Request,Response.CompleteListener> getPushListener()

getTrailers

public java.util.function.Supplier<org.eclipse.jetty.http.HttpFields> getTrailers()

abort

public boolean abort(java.lang.Throwable cause)

Description copied from interface: Request

Attempts to abort the send of this request.

Specified by:

abort in interface Request

Parameters:

cause - the abort cause, must not be null

Returns:

whether the abort succeeded

getAbortCause

public java.lang.Throwable getAbortCause()

Specified by:

getAbortCause in interface Request

Returns:

the abort cause passed to Request.abort(Throwable), or null if this request has not been aborted

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
