                      Buffer payload)
```
    Parameters:
    
    rawInitialBuffer - the raw initial line, which is either a request or a response line (hopefully anyway, we won't know until we try!_

    toString in class Object
  - getContent
```
public final Object getContent()
                        throws SipParseException
```
    Description copied from interface: SipMessage
    
    Returns the content (payload) of the SipMessage as an Object. If the ContentTypeHeader indicates a content type that is known (such as an sdp) then an attempt to parse the content into that type is made. If the payload is unknown then a Buffer representing the payload will be returned.
    
    Specified by:
    
    getContent in interface SipMessage
    
    Returns:
    
    Throws:
    
    SipParseException - in case anything goes wrong when trying to frame the content in any way.
  - getRawContent
```
public final Buffer getRawContent()
```
    Description copied from interface: SipMessage
    
    Get the content as a Buffer.
    
    Specified by:
    
    getRawContent in interface SipMessage
    
    Returns:
  - hasContent
```
public final boolean hasContent()
```
    Description copied from interface: SipMessage
    
    Checks whether this SipMessage is carrying anything in its message body.
    
    Specified by:
    
    hasContent in interface SipMessage
    
    Returns:
    
    true if this SipMessage has a message body, false otherwise.
  - toRequest
```
public SipRequest toRequest()
                     throws ClassCastException
```
    Description copied from interface: SipMessage
    
    Got tired of casting the SipMessage into a SipRequest so you can use this method instead. Just a short cut for: (SipRequest)sipMessage;
    
    Specified by:
    
    toRequest in interface SipMessage
    
    Returns:
    
    this but casted into a SipRequest
    
    Throws:
    
    ClassCastException - in case this SipMessage is actually a SipResponse.
  - toResponse
```
public SipResponse toResponse()
                       throws ClassCastException
```
    Description copied from interface: SipMessage
    
    Got tired of casting the SipMessage into a SipResponse so you can use this method instead. Just a short cut for: (SipResponse)sipMessage;
    
    Specified by:
    
    toResponse in interface SipMessage
    
    Returns:
    
    this but casted into a SipResponse
    
    Throws:
    
    ClassCastException - in case this SipMessage is actually a SipResponse.
  - createResponse
```
public SipResponse createResponse(int responseCode)
                           throws SipParseException,
                                  ClassCastException
```
    Description copied from interface: SipMessage
    Create a new response based on this SipRequest. If this SipMessage is not a SipRequest then a ClassCastException will be thrown. Only the mandatory headers from the SipRequest are copied. Those mandatory headers are:
    Specified by:
    
    createResponse in interface SipMessage
    
    Returns:
    
    Throws:
    
    SipParseException - in case anything goes wrong when parsing out headers from the SipRequest
    
    ClassCastException
  - toBuffer
```
public Buffer toBuffer()
```
    Description copied from interface: SipMessage
    
    Get the Buffer that is representing this SipMessage. Note, the data behind the buffer is shared with the actual SipMessage so any changes to the Buffer will affect this SipMessage. Hence, by changing this buffer directly, you bypass all checks for valid inputs and the end-result of doing so is undefined (most likely you will either blow up at some point or you will end up sending garbage across the network).
    
    Specified by:
    
    toBuffer in interface SipMessage
    
    Returns:
  - cloneHeaders
```
protected Buffer cloneHeaders()
```
    Helper method to clone all the headers into one continuous buffer.
    
    Returns:
  - clonePayload
```
protected Buffer clonePayload()
```
    Helper method to clone the payload.
    
    Returns:
  - transferHeaders
```
protected void transferHeaders(Buffer dst)
```
    Transfer the data of all headers into the supplied buffer.
    
    Parameters:
    
    dst -
  - clone
```
public abstract SipMessage clone()
```
    Description copied from interface: SipMessage
    
    Perform a deep clone of this SipMessage.
    
    Specified by:
    
    clone in interface SipMessage

    clone in class Object
