Method Detail

headerLength

@HeaderLength
public static int headerLength(JBuffer buffer,
                                            int offset)

Header length.

Parameters:

buffer - the buffer

offset - the offset

Returns:

the int

decodeFirstLine

protected abstract void decodeFirstLine(java.lang.String line)

Decode first line.

Parameters:

line - the line

decodeHeader

protected void decodeHeader()

Decode the http/sip header. First we need to convert raw bytes to a char's we can deal with since Http/sip header is text based. Once converted we can then accurately determine the Http/sip header length, type of request, etc...

Overrides:

decodeHeader in class JHeader

getMessageType

public AbstractMessageHeader.MessageType getMessageType()

Gets the message type.

Returns:

the message type

setMessageType

public void setMessageType(AbstractMessageHeader.MessageType type)

Sets the message type.

Parameters:

type - the new message type
