Constructor Detail

InternalInputBuffer

public InternalInputBuffer(Request request)

                           int headerBufferSize)

Alternate 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

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

Throws:

IOException

parseHeader

public boolean parseHeader()
                    throws IOException

Parse an HTTP header.

Returns:

false after reading a blank line (which indicates that the HTTP header parsing is done

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

protected boolean fill(boolean block)
                throws IOException

Specified by:

fill in class AbstractInputBuffer

Throws:

IOException
