Class TSdpRtpmapValue

class TSdpRtpmapValue;

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.

Members

Defined in TSdpRtpmapValue:
DecodeL(), EncodeL(), TSdpRtpmapValue()

IMPORT_C TSdpRtpmapValue(const TPtrC8 &aEncodingName, const TPtrC8 &aClockrate, const TPtrC8 &aEncodingParameters);

Description

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

const TPtrC8 &aEncodingName Valid rtpmap encoding name value. const TPtrC8 &aClockrate Valid rtpmap clockrate value. const TPtrC8 &aEncodingParameters Valid rtpmap encoding parameter list.

static IMPORT_C TSdpRtpmapValue DecodeL(const TDesC8 &aText);

Description

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

const TDesC8 &aText String containing the value of an rtpmap attribute.

Return value

TSdpRtpmapValue a new instance

Leave codes

KErrArgument if parsing fails.

IMPORT_C HBufC8 *EncodeL() const;

Description

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.

Return value

HBufC8 * Encoded value. Ovnership of buffer is changed to caller.
