Constructor Detail

InternalAprInputBuffer

public InternalAprInputBuffer(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<Long>

parseRequestLine

public boolean parseRequestLine(boolean useAvailableData)
                         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<Long>

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<Long>

Throws:

IOException

doRead

public int doRead(ByteChunk chunk,
                  Request req)
           throws IOException

Read some bytes.

Specified by:

doRead in interface InputBuffer

Overrides:

doRead in class AbstractInputBuffer<Long>

Throws:

IOException

init

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

Specified by:

init in class AbstractInputBuffer<Long>

Throws:

IOException

fill

protected boolean fill(boolean block)
                throws IOException

Specified by:

fill in class AbstractInputBuffer<Long>

Throws:

IOException

fill

protected boolean fill()
                throws IOException

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

Returns:

false if at end of stream

Throws:

IOException
