Method Detail

getAsyncContext
public AsyncContext getAsyncContext()
Gets the AsyncContext from this AsyncEvent.- Returns:
- the AsyncContext that was used to initialize this AsyncEvent
-
getSuppliedRequest
public ServletRequest getSuppliedRequest()
Gets the ServletRequest from this AsyncEvent.If the AsyncListener to which this AsyncEvent is being delivered was added using
AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the returned ServletRequest will be the same as the one supplied to the above method. If the AsyncListener was added viaAsyncContext.addListener(AsyncListener), this method must return null.- Returns:
- the ServletRequest that was used to initialize this AsyncEvent, or null if this AsyncEvent was initialized without any ServletRequest
-
getSuppliedResponse
public ServletResponse getSuppliedResponse()
Gets the ServletResponse from this AsyncEvent.If the AsyncListener to which this AsyncEvent is being delivered was added using
AsyncContext.addListener(AsyncListener, ServletRequest, ServletResponse), the returned ServletResponse will be the same as the one supplied to the above method. If the AsyncListener was added viaAsyncContext.addListener(AsyncListener), this method must return null.- Returns:
- the ServletResponse that was used to initialize this AsyncEvent, or null if this AsyncEvent was initialized without any ServletResponse
-
getThrowable
public Throwable getThrowable()
Gets the Throwable from this AsyncEvent.- Returns:
- the Throwable that was used to initialize this AsyncEvent, or null if this AsyncEvent was initialized without any Throwable
