Constructor Detail

InternalNioInputBuffer

public InternalNioInputBuffer(Request request,
                              int headerBufferSize)

Alternate constructor.

Method Detail

recycle

public void recycle()

Recycle the input buffer. This should be called when closing the connection.

Overrides:

recycle in class AbstractInputBuffer<NioChannel>

nextRequest

public void nextRequest()

End processing of current HTTP request. Note: All bytes of the current request should have been already consumed. This method only resets all the pointers so that we are ready to parse the next HTTP request.

Overrides:

nextRequest in class AbstractInputBuffer<NioChannel>

parseRequestLine

public boolean parseRequestLine(boolean useAvailableDataOnly)
                         throws IOException

Read the request line. This function is meant to be used during the HTTP request header parsing. Do NOT attempt to read the request body using it.

Specified by:

parseRequestLine in class AbstractInputBuffer<NioChannel>

Returns:

true if data is properly fed; false if no data is available immediately and thread should be freed

Throws:

IOException - If an exception occurs during the underlying socket read operations, or if the given buffer is not big enough to accommodate the whole line.

parseHeaders

public boolean parseHeaders()
                     throws IOException

Parse the HTTP headers.

Specified by:

parseHeaders in class AbstractInputBuffer<NioChannel>

Throws:

IOException

getParsingRequestLinePhase

public int getParsingRequestLinePhase()

init

protected void init(SocketWrapper<NioChannel> socketWrapper,
                    AbstractEndpoint endpoint)
             throws IOException

Specified by:

init in class AbstractInputBuffer<NioChannel>

Throws:

IOException

fill

protected boolean fill(boolean block)
                throws IOException,
                       EOFException

Fill the internal buffer using data from the underlying input stream.

Specified by:

fill in class AbstractInputBuffer<NioChannel>

Returns:

false if at end of stream

Throws:

IOException

EOFException

fill

protected boolean fill(boolean timeout,
                       boolean block)
                throws IOException,
                       EOFException

Throws:

IOException

EOFException
