class CElementParser : public CBase;
Parser for SDP attribute values.
The class parses an input buffer containing an attribute value into its constituent data elements. It calls an MSdpElementBuilder
object each time a data element is decoded.
This parser can parse incrementally, and be fed new data as it arrives.

static IMPORT_C CElementParser *NewL(MSdpElementBuilder *aBuilder);
Allocates and constructs a new CElementParser object.

|
IMPORT_C TInt ParseElementsL(const TDesC8 &aData);
Parses a data buffer into the currently set MSdpElementBuilder
interface.
If a whole number of data elements can not be parsed out of aData, the number of bytes left unparsed is returned. Those bytes should be prepended to the buffer when the function is next called.
|
|
IMPORT_C TBool BufferedParseL(const TDesC8 &aData);
Parse out some encoded data, with transparent buffering of unparsed data between calls.
The function stores any incompletely parsed data from a previous call, and automatically prepends to the data buffer when it is next called.
If the function leaves, the unparsed data will be deleted. This means it will not be possible to continue with this data stream;
Reset()
should be called before the next call to this function.
|
|
IMPORT_C void Reset(MSdpElementBuilder *aBuilder);
Resets the parser's buffers to be empty, and resets the element builder object used.
