Detailed Description

Utility class for manipulating the value of an rtpmap-attribute.

The normative reference for correct formatting and values is draft-ietf-mmusic-sdp-new-14 unless specified otherwise in member documentation. The implementation supports this normative reference, but does not enforce it fully.

Constructor & Destructor Documentation

IMPORT_C TSdpRtpmapValue::TSdpRtpmapValue	(�	const TPtrC8 &�	aEncodingName,
		const TPtrC8 &�	aClockrate,
		const TPtrC8 &�	aEncodingParameters
	)�

�

Initializes the instance to refer to the given rtpmap components.

The parameters must stay in scope as long as this instance exists. Otherwise, the member variables of this class will point to a released memory.

Parameters:

	aEncodingName�	Valid rtpmap encoding name value.
	aClockrate�	Valid rtpmap clockrate value.
	aEncodingParameters�	Valid rtpmap encoding parameter list.

Member Function Documentation

static IMPORT_C TSdpRtpmapValue TSdpRtpmapValue::DecodeL (� const TDesC8 &� aText �)� [static]

�

Tries to parse a string as an rtpmap attribute value up to the end of the string or CRLF, whichever comes first, and set pointers to the components found.

The parameter must stay in scope as long as this instance exists. Otherwise, the member variables of this class will point to a released memory.

Parameters:

aText�

String containing the value of an rtpmap attribute.

Returns:: a new instance

Leave:: KErrArgument if parsing fails.

IMPORT_C HBufC8* TSdpRtpmapValue::EncodeL

Outputs the attribute value formatted according to SDP syntax.

The field terminating CRLF is not included in the output. When constructing CSdpFmtAttributeField, return value of this function can be used as aValue in CSdpFmtAttributeField::NewL (RStringF aAttribute, const TDesC8& aFormat, const TDesC8& aValue) function.
