start
Description copied from interface:javax.servlet.AsyncContext
Starts a new thread to process the asynchronous request- Specified by:
start
in interfaceAsyncContext
- Parameters:
run
- a Runnable that the new thread will run
-
addListener
Description copied from interface:javax.servlet.AsyncContext
Adds an event listener that will be called for different AsyncEvents fire- Specified by:
addListener
in interfaceAsyncContext
- Parameters:
listener
- an AsyncListener that will be called with AsyncEvent objects
-
addListener
public void addListener(AsyncListener listener, ServletRequest servletRequest, ServletResponse servletResponse) Description copied from interface:javax.servlet.AsyncContext
Adds an event listener that will be called when different AsyncEvents fire- Specified by:
addListener
in interfaceAsyncContext
- Parameters:
listener
- an AsyncListener that will be called with AsyncEvent objectsservletRequest
- the ServletRequest that will be passed with the AsyncEventservletResponse
- the ServletResponse that will be passed with the AsyncEvent
-
createListener
Description copied from interface:javax.servlet.AsyncContext
Creates and returns an AsyncListener object- Specified by:
createListener
in interfaceAsyncContext
- Type Parameters:
T
- The type to create that extends AsyncListener- Parameters:
clazz
- The class to instantiate to create the listener- Returns:
- the newly created AsyncListener object
- Throws:
ServletException
- if the listener cannot be created
-
recycle
public void recycle() -
isStarted
public boolean isStarted() -
setStarted
public void setStarted(Context context, ServletRequest request, ServletResponse response, boolean originalRequestResponse) -
hasOriginalRequestAndResponse
public boolean hasOriginalRequestAndResponse()- Specified by:
hasOriginalRequestAndResponse
in interfaceAsyncContext
- Returns:
- true if the Request and Response are the original ones
-
doInternalDispatch
- Throws:
ServletException
IOException
-
getTimeout
public long getTimeout()Description copied from interface:javax.servlet.AsyncContext
Get the current timeout.- Specified by:
getTimeout
in interfaceAsyncContext
- Returns:
- The timeout in milliseconds. 0 or less indicates no timeout.
-
setTimeout
public void setTimeout(long timeout) Description copied from interface:javax.servlet.AsyncContext
Set the timeout.- Specified by:
setTimeout
in interfaceAsyncContext
- Parameters:
timeout
- The timeout in milliseconds. 0 or less indicates no timeout.
-
isAvailable
public boolean isAvailable()Description copied from interface:AsyncContextCallback
Reports if the web application associated with this async request is available.- Specified by:
isAvailable
in interfaceAsyncContextCallback
- Returns:
true
if the associated web application is available, otherwisefalse
-
setErrorState
-
incrementInProgressAsyncCount
public void incrementInProgressAsyncCount()Description copied from interface:AsyncContextCallback
Used to notify the Context that async processing has started. Specifically, for the counting of in-progress async requests to work correctly, this must be called exactly once every time theAsyncStateMachine
transitions from DISPATCHED to any other state.- Specified by:
incrementInProgressAsyncCount
in interfaceAsyncContextCallback
-
decrementInProgressAsyncCount
public void decrementInProgressAsyncCount()Description copied from interface:AsyncContextCallback
Used to notify the Context that async processing has ended. Specifically, for the counting of in-progress async requests to work correctly, this must be called exactly once every time theAsyncStateMachine
transitions to DISPATCHED from any other state.- Specified by:
decrementInProgressAsyncCount
in interfaceAsyncContextCallback
