Detailed Description

Represents an SIP request first line. The first line includes 3 parameters: SIP method (e.g INVITE, ACK, BYE, etc.), URI (e.g sip:bla@b.nosp@m.la.c.nosp@m.om:12345) and SIP version (usually SIP/2.0). All these parameters are included in this class, and the user can retrieve or set them. This class cannot be instantiated by users, it's created inside SipRequestLayer and user can get a pointer to an instance of it. All "getters" of this class retrieve the actual data of the SIP request and the "setters" actually change the packet data. Since SIP is a textual protocol, most fields aren't of fixed size and this also applies to the first line parameters. So many "setter" methods of this class may need to shorten or extend the data in SipRequestLayer. These methods will return a false value if this action failed

Member Function Documentation

getMethod()

SipRequestLayer::SipMethod pcpp::SipRequestFirstLine::getMethod ( ) const

inline

Returns

The SIP request method

getSize()

int pcpp::SipRequestFirstLine::getSize ( ) const

inline

Returns

The size in bytes of the SIP request first line

getUri()

std::string pcpp::SipRequestFirstLine::getUri

(

)

const

Returns

A copied version of the URI (notice changing the return value won't change the actual data of the packet)

getVersion()

std::string pcpp::SipRequestFirstLine::getVersion ( ) const

inline

Returns

The SIP version

isComplete()

bool pcpp::SipRequestFirstLine::isComplete ( ) const

inline

As explained in SipRequestLayer, a SIP message can sometimes spread over more than 1 packet, so when looking at a single packet the header can be partial. Same goes for the first line - it can spread over more than 1 packet. This method returns an indication whether the first line is partial

Returns

False if the first line is partial, true if it's complete

parseMethod()

static SipRequestLayer::SipMethod pcpp::SipRequestFirstLine::parseMethod ( const char *  data, size_t  dataLen  )

static

A static method for parsing the SIP method out of raw data

Parameters

[in]	data	The raw data
[in]	dataLen	The raw data length

Returns

The parsed SIP method

setMethod()

bool pcpp::SipRequestFirstLine::setMethod

(

SipRequestLayer::SipMethod

newMethod

)

Set the SIP request method

Parameters

[in]

newMethod

The method to set

Returns

False if newMethod is SipRequestLayer::SipMethodUnknown or if shortening/extending the SipRequestLayer data failed. True otherwise

setUri()

bool pcpp::SipRequestFirstLine::setUri

(

const std::string &

newUri

)

Set the URI

Parameters

[in]

newUri

The URI to set

Returns

False if shortening/extending the SipRequestLayer data failed. True otherwise
