addListener

public void addListener(javax.servlet.AsyncListener listener)

Specified by:

addListener in interface javax.servlet.AsyncContext

addListener

public void addListener(javax.servlet.AsyncListener listener,
                        javax.servlet.ServletRequest request,
                        javax.servlet.ServletResponse response)

Specified by:

addListener in interface javax.servlet.AsyncContext

addContinuationListener

public void addContinuationListener(ContinuationListener listener)

Specified by:

addContinuationListener in interface Continuation

setTimeout

public void setTimeout(long ms)

Specified by:

setTimeout in interface javax.servlet.AsyncContext

Specified by:

setTimeout in interface Continuation

getTimeout

public long getTimeout()

Specified by:

getTimeout in interface javax.servlet.AsyncContext

getAsyncEventState

public AsyncContinuation.AsyncEventState getAsyncEventState()

isResponseWrapped

public boolean isResponseWrapped()

Specified by:

isResponseWrapped in interface Continuation

See Also:

Continuation.isResponseWrapped()

isInitial

public boolean isInitial()

Specified by:

isInitial in interface Continuation

isSuspended

public boolean isSuspended()

toString

public String toString()

Overrides:

toString in class Object

getStatusString

public String getStatusString()

handling

protected boolean handling()

Returns:

false if the handling of the request should not proceed

suspend

protected void suspend(javax.servlet.ServletContext context,
                       javax.servlet.ServletRequest request,
                       javax.servlet.ServletResponse response)

unhandle

protected boolean unhandle()

Signal that the HttpConnection has finished handling the request. For blocking connectors, this call may block if the request has been suspended (startAsync called).

Returns:

true if handling is complete, false if the request should be handled again (eg because of a resume that happened before unhandle was called)
