Method Detail

read

public void read(InputStream in,
        boolean createBody)
          throws IOException,
                 EndOfStreamException

If the message is HTTP 1.1 but the header has no information about the content length, then an assumption is made that after the body the server will send an EOF. So the body is read till end of the stream. See http://www.ietf.org/rfc/rfc2145.txt

Throws:

IOException

EndOfStreamException

readBody

public void readBody()
              throws IOException

Throws:

IOException

getBody

public AbstractBody getBody()

getBodyAsStream

public InputStream getBodyAsStream()

setBody

public void setBody(AbstractBody b)

setBodyContent

public void setBodyContent(byte[] content)

createBody

protected void createBody(InputStream in)
                   throws IOException

Throws:

IOException

parseStartLine

protected abstract void parseStartLine(InputStream in)
                                throws IOException,
                                       EndOfStreamException

Throws:

IOException

EndOfStreamException

getHeader

public Header getHeader()

release

public void release()

preserve synchronized keyword, notify method is called

hasMsgReleased

public boolean hasMsgReleased()

setHeader

public void setHeader(Header srcHeader)

write

public final void write(OutputStream out)
                 throws IOException

Throws:

IOException

writeStartLine

public void writeStartLine(OutputStream out)
                    throws IOException

The start line supposedly only contains ASCII characters. But since HttpUtil.readLine(InputStream) converts the input byte-by-byte to char-by-char, we use ISO-8859-1 for output.

Throws:

IOException

getStartLine

public abstract String getStartLine()

isHTTP11

public boolean isHTTP11()

isHTTP10

public boolean isHTTP10()

getVersion

public String getVersion()

setVersion

public void setVersion(String version)

toString

public String toString()

Overrides:

toString in class Object

isKeepAlive

public boolean isKeepAlive()

getErrorMessage

public String getErrorMessage()

setErrorMessage

public void setErrorMessage(String errorMessage)

getName

public String getName()

isBodyEmpty

public boolean isBodyEmpty()
                    throws IOException

Throws:

IOException
