Method Detail
-
process
AbstractEndpoint.Handler.SocketState process(SocketWrapperBase<?> socketWrapper, SocketEvent status) throws java.io.IOException
Process a connection. This is called whenever an event occurs (e.g. more data arrives) that allows processing to continue for a connection that is not currently being processed.- Parameters:
socketWrapper
- The connection to processstatus
- The status of the connection that triggered this additional processing- Returns:
- The state the caller should put the socket in when this method returns
- Throws:
java.io.IOException
- If an I/O error occurs during the processing of the request
-
getUpgradeToken
UpgradeToken getUpgradeToken()
Generate an upgrade token.- Returns:
- An upgrade token encapsulating the information required to process the upgrade request
- Throws:
java.lang.IllegalStateException
- if this is called on a Processor that does not support upgrading
-
isUpgrade
boolean isUpgrade()
- Returns:
true
if the Processor is currently processing an upgrade request, otherwisefalse
-
isAsync
boolean isAsync()
-
timeoutAsync
void timeoutAsync(long now)
Check this processor to see if the timeout has expired and process a timeout if that is that case.Note: The name of this method originated with the Servlet 3.0 asynchronous processing but evolved over time to represent a timeout that is triggered independently of the socket read/write timeouts.
- Parameters:
now
- The time (as returned bySystem.currentTimeMillis()
to use as the current time to determine whether the timeout has expired. If negative, the timeout will always be treated as ifq it has expired.
-
getRequest
Request getRequest()
- Returns:
- The request associated with this processor.
-
recycle
void recycle()
Recycle the processor, ready for the next request which may be on the same connection or a different connection.
-
setSslSupport
void setSslSupport(SSLSupport sslSupport)
Set the SSL information for this HTTP connection.- Parameters:
sslSupport
- The SSL support object to use for this connection
-
getLeftoverInput
java.nio.ByteBuffer getLeftoverInput()
Allows retrieving additional input during the upgrade process.- Returns:
- leftover bytes
- Throws:
java.lang.IllegalStateException
- if this is called on a Processor that does not support upgrading
-
pause
void pause()
Informs the processor that the underlying I/O layer has stopped accepting new connections. This is primarily intended to enable processors that use multiplexed connections to prevent further 'streams' being added to an existing multiplexed connection.
-
checkAsyncTimeoutGeneration
boolean checkAsyncTimeoutGeneration()
Check to see if the async generation (each cycle of async increments the generation of the AsyncStateMachine) is the same as the generation when the most recent async timeout was triggered. This is intended to be used to avoid unnecessary processing.- Returns:
true
If the async generation has not changed since the async timeout was triggered
