UpgradeProcessorBase

public UpgradeProcessorBase(UpgradeToken upgradeToken)

Method Detail

isUpgrade

public final boolean isUpgrade()

Specified by:

isUpgrade in interface Processor

Returns:

true if the Processor is currently processing an upgrade request, otherwise false

getUpgradeToken

public UpgradeToken getUpgradeToken()

Description copied from interface: Processor

Generate an upgrade token.

Specified by:

getUpgradeToken in interface Processor

Returns:

An upgrade token encapsulating the information required to process the upgrade request

recycle

public final void recycle()

Description copied from interface: Processor

Recycle the processor, ready for the next request which may be on the same connection or a different connection.

Specified by:

recycle in interface Processor

service

public final AbstractEndpoint.Handler.SocketState service(SocketWrapperBase<?> socketWrapper)
                                                   throws IOException

Description copied from class: AbstractProcessorLight

Service a 'standard' HTTP request. This method is called for both new requests and for requests that have partially read the HTTP request line or HTTP headers. Once the headers have been fully read this method is not called again until there is a new HTTP request to process. Note that the request type may change during processing which may result in one or more calls to AbstractProcessorLight.dispatch(SocketEvent). Requests may be pipe-lined.

Specified by:

service in class AbstractProcessorLight

Parameters:

socketWrapper - The connection to process

Returns:

The state the caller should put the socket in when this method returns

Throws:

IOException - If an I/O error occurs during the processing of the request

asyncPostProcess

public final AbstractEndpoint.Handler.SocketState asyncPostProcess()

Specified by:

asyncPostProcess in class AbstractProcessorLight

isAsync

public final boolean isAsync()

Specified by:

isAsync in interface Processor

getRequest

public final Request getRequest()

Specified by:

getRequest in interface Processor

Returns:

The request associated with this processor.

getLeftoverInput

public ByteBuffer getLeftoverInput()

Description copied from interface: Processor

Allows retrieving additional input during the upgrade process.

Specified by:

getLeftoverInput in interface Processor

Returns:

leftover bytes

timeoutAsync

public void timeoutAsync(long now)

Description copied from interface: Processor

Check this processor to see if the async timeout has expired and process a timeout if that is that case.

Specified by:

timeoutAsync in interface Processor

Parameters:

now - The time (as returned by System.currentTimeMillis() to use as the current time to determine whether the async timeout has expired. If negative, the timeout will always be treated as if it has expired.
