Detailed Description

This class extends PURL to include displayname, optional "<>" delimiters and extended parameters - like tag. It may be used for From:, To: and Contact: lines.

Constructor & Destructor Documentation

SIPURL::SIPURL

(

)

SIPURL::SIPURL	(	const char *	cstr,
		const char *	defaultScheme = NULL
	)

str goes straight to Parse()

Parameters:

cstr	C string representation of the URL.
defaultScheme	Default scheme for URL

SIPURL::SIPURL	(	const PString &	str,
		const char *	defaultScheme = NULL
	)

str goes straight to Parse()

Parameters:

str	String representation of the URL.
defaultScheme	Default scheme for URL

SIPURL::SIPURL	(	const PString &	name,
		const OpalTransportAddress &	address,
		WORD	listenerPort = 0
	)

If name does not start with 'sip' then construct URI in the form sip:name:port;transport=transport where host comes from address, port is listenerPort or port from address if that was 0 transport is udp unless address specified tcp Send name starting with 'sip' or constructed URI to Parse()

Member Function Documentation

virtual Comparison SIPURL::Compare

(

const PObject &

obj

)

const [virtual]

Compare the two SIPURLs and return their relative rank. Note that does an intelligent comparison according to the rules in RFC3261 Section 19.1.4.

Returns:

LessThan#, EqualTo# or GreaterThan# according to the relative rank of the objects.

Parameters:

obj	Object to compare against.

PString SIPURL::AsQuotedString

(

)

const

Returns complete SIPURL as one string, including displayname (in quotes) and address in angle brackets.

PString SIPURL::GetDisplayName

(

PBoolean

useDefault = PTrue

)

const

Returns display name only

void SIPURL::SetDisplayName

(

const PString &

str

)

[inline]

PString SIPURL::GetFieldParameters

(

)

const [inline]

Returns the field parameter (outside of <>)

OpalTransportAddress SIPURL::GetHostAddress

(

)

const

Get the host and port as a transpoprt address.

void SIPURL::Sanitise

(

UsageContext

context

)

Removes tag parm & query vars and recalculates urlString (scheme, user, password, host, port & URI parms (like transport)) which are not allowed in the context specified, e.g. Request-URI etc According to RFC3261, 19.1.1 Table 1

Parameters:

context

Context for URI

PBoolean SIPURL::AdjustToDNS

(

PINDEX

entry = 0

)

This will adjust the current URL according to RFC3263, using DNS SRV records.

Returns:

FALSE if DNS is available but entry is larger than last SRV record entry, TRUE if DNS lookup fails or no DNS is available

Parameters:

entry

Entry in the SRV record to adjust to

virtual PBoolean SIPURL::InternalParse	(	const char *	cstr,
		const char *	defaultScheme
	)			[protected, virtual]

Parses name-addr, like: "displayname"<scheme:user:password:port;transport=type>;tag=value into: displayname (quotes around name are optional, all before '<' is used) scheme username password hostname port pathStr path paramVars queryVars fragment

Note that tag parameter outside of <> will be lost, but tag in URL without <> will be kept until Sanitise()
