Constructor Detail

InternalInputBuffer

public InternalInputBuffer(Request request,
                           int headerBufferSize)

Default constructor.

Method Detail

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<Socket>

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<Socket>

Throws:

IOException

recycle

public void recycle()

Description copied from class: AbstractInputBuffer

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

Overrides:

recycle in class AbstractInputBuffer<Socket>

init

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

Specified by:

init in class AbstractInputBuffer<Socket>

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

fill
