Method Detail- 
flushBufferedWriteprotected boolean flushBufferedWrite() throws java.io.IOExceptionDescription copied from class:AbstractProcessorFlush any pending writes. Used during non-blocking writes to flush any remaining data from a previous incomplete write.- Specified by:
- flushBufferedWritein class- AbstractProcessor
- Returns:
- trueif data remains to be flushed at the end of method
- Throws:
- java.io.IOException- If an I/O error occurs while attempting to flush the data
 
 - 
dispatchNonBlockingReadprotected void dispatchNonBlockingRead() Description copied from class:AbstractProcessorPerform any necessary processing for a non-blocking read before dispatching to the adapter.- Overrides:
- dispatchNonBlockingReadin class- AbstractProcessor
 
 - 
dispatchEndRequestprotected AbstractEndpoint.Handler.SocketState dispatchEndRequest() Description copied from class:AbstractProcessorPerform any necessary clean-up processing if the dispatch resulted in the completion of processing for the current request.- Specified by:
- dispatchEndRequestin class- AbstractProcessor
- Returns:
- The state to return for the socket once the clean-up for the current request has completed
 
 - 
servicepublic AbstractEndpoint.Handler.SocketState service(SocketWrapperBase<?> socket) throws java.io.IOException Description copied from class:AbstractProcessorLightService 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 toAbstractProcessorLight.dispatch(SocketEvent). Requests may be pipe-lined.- Specified by:
- servicein class- AbstractProcessorLight
- Parameters:
- socket- The connection to process
- 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
 
 - 
recyclepublic void recycle() Description copied from interface:ProcessorRecycle the processor, ready for the next request which may be on the same connection or a different connection.- Specified by:
- recyclein interface- Processor
- Overrides:
- recyclein class- AbstractProcessor
 
 - 
pausepublic void pause() Description copied from interface:ProcessorInforms 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.
 - 
refillReadBufferprotected boolean refillReadBuffer(boolean block) throws java.io.IOExceptionGet more request body data from the web server and store it in the internal buffer.- Parameters:
- block-- trueif this is blocking IO
- Returns:
- trueif there is more data,- falseif not.
- Throws:
- java.io.IOException- An IO error occurred
 
 - 
populateHostprotected void populateHost() Called when a host header is not present in the request (e.g. HTTP/1.0). It populates the server name with appropriate information. The source is expected to vary by protocol.The default implementation is a NO-OP. This implementation populates the server name from the local name provided by the AJP message. - Overrides:
- populateHostin class- AbstractProcessor
 
 - 
populatePortprotected void populatePort() Called when a host header is not present or is empty in the request (e.g. HTTP/1.0). It populates the server port with appropriate information. The source is expected to vary by protocol.The default implementation is a NO-OP. This implementation populates the server port from the local port provided by the AJP message. - Overrides:
- populatePortin class- AbstractProcessor
 
 - 
prepareResponseprotected final void prepareResponse() throws java.io.IOExceptionWhen committing the response, we have to validate the set of headers, as well as setup the response filters.- Specified by:
- prepareResponsein class- AbstractProcessor
- Throws:
- java.io.IOException
 
 - 
flushprotected final void flush() throws java.io.IOExceptionCallback to write data from the buffer.- Specified by:
- flushin class- AbstractProcessor
- Throws:
- java.io.IOException
 
 - 
finishResponseprotected final void finishResponse() throws java.io.IOExceptionFinish AJP response.- Specified by:
- finishResponsein class- AbstractProcessor
- Throws:
- java.io.IOException
 
 - 
ackprotected final void ack(ContinueResponseTiming continueResponseTiming) - Specified by:
- ackin class- AbstractProcessor
 
 - 
availableprotected final int available(boolean doRead) - Specified by:
- availablein class- AbstractProcessor
 
 - 
setRequestBodyprotected final void setRequestBody(ByteChunk body) - Specified by:
- setRequestBodyin class- AbstractProcessor
 
 - 
setSwallowResponseprotected final void setSwallowResponse() - Specified by:
- setSwallowResponsein class- AbstractProcessor
 
 - 
disableSwallowRequestprotected final void disableSwallowRequest() - Specified by:
- disableSwallowRequestin class- AbstractProcessor
 
 - 
getPopulateRequestAttributesFromSocketprotected final boolean getPopulateRequestAttributesFromSocket() Description copied from class:AbstractProcessorProcessors that populate request attributes directly (e.g. AJP) should over-ride this method and returnfalse.- Overrides:
- getPopulateRequestAttributesFromSocketin class- AbstractProcessor
- Returns:
- trueif the SocketWrapper should be used to populate the request attributes, otherwise- false.
 
 - 
populateRequestAttributeRemoteHostprotected final void populateRequestAttributeRemoteHost() Description copied from class:AbstractProcessorPopulate the remote host request attribute. Processors (e.g. AJP) that populate this from an alternative source should override this method.- Overrides:
- populateRequestAttributeRemoteHostin class- AbstractProcessor
 
 - 
populateSslRequestAttributesprotected final void populateSslRequestAttributes() Description copied from class:AbstractProcessorPopulate the TLS related request attributes from theSSLSupportinstance associated with this processor. Protocols that populate TLS attributes from a different source (e.g. AJP) should override this method.- Overrides:
- populateSslRequestAttributesin class- AbstractProcessor
 
 - 
isRequestBodyFullyReadprotected final boolean isRequestBodyFullyRead() - Specified by:
- isRequestBodyFullyReadin class- AbstractProcessor
 
 - 
registerReadInterestprotected final void registerReadInterest() - Specified by:
- registerReadInterestin class- AbstractProcessor
 
 - 
isReadyForWriteprotected final boolean isReadyForWrite() - Specified by:
- isReadyForWritein class- AbstractProcessor
 
 -
