public boolean isCompletedBeforeInitialRequestDone()

createListener

public <T extends jakarta.servlet.AsyncListener> T createListener(Class<T> clazz)
                                                           throws jakarta.servlet.ServletException

Specified by:

createListener in interface jakarta.servlet.AsyncContext

Throws:

jakarta.servlet.ServletException

setTimeout

public void setTimeout(long timeout)

Specified by:

setTimeout in interface jakarta.servlet.AsyncContext

getTimeout

public long getTimeout()

Specified by:

getTimeout in interface jakarta.servlet.AsyncContext

handleError

public void handleError(Throwable error)

initialRequestDone

public void initialRequestDone()

Called by the container when the initial request is finished. If this request has a dispatch or complete call pending then this will be started.

handleCompletedBeforeInitialRequestDone

public void handleCompletedBeforeInitialRequestDone()

addAsyncTask

public void addAsyncTask(Runnable runnable)

Adds a task to be run to the async context. These tasks are run one at a time, after the initial request is finished. If the request is dispatched before the initial request is complete then these tasks will not be run

This method is intended to be used to queue read and write tasks for async streams, to make sure that multiple threads do not end up working on the same exchange at once

Parameters:

runnable - The runnable
