| class MSdpElementBuilder |
Constructs an attribute value, or a set of attributes, from multiple data elements.
The builder interface is used for building single attribute values, and sets of attribute value, attribute ID pairs, as for example in a service record.
In particular, the builder interface can be implemented to receive the results from CSdpAgent attribute queries.
Each member function itself returns an MSdpElementBuilder interface that can then be used to add further elements.
For more on the format of attribute values, see [BS1 Service Discovery Protocol 3].
Note that the interface defines each function to leave with the error KErrGeneral.

| IMPORT_C void | MSEB_ExtensionInterfaceL(TUid, void *&) |
| IMPORT_C MSdpElementBuilder * | StartListL() |
| IMPORT_C MSdpElementBuilder * | BuildBooleanL | ( | TBool | aBool | ) | [virtual] |
Adds a Boolean element.
| TBool aBool | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildDEAL | ( | ) | [virtual] |
Adds a (header for a) Data element alternative (DEA), a data element whose data field is a sequence of data elements from which one data element is to be selected.
This should be followed by a call to StartListL(), and then calls to add elements to the list.
| IMPORT_C MSdpElementBuilder * | BuildDESL | ( | ) | [virtual] |
Adds a (header for a) Data element sequence (DES), a data element whose data field is a sequence of data elements.
This should be followed by a call to StartListL(), and then calls to add elements to the list.
| IMPORT_C MSdpElementBuilder * | BuildIntL | ( | const TDesC8 & | aInt | ) | [virtual] |
Adds a signed integer element.
| const TDesC8 & aInt | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildStringL | ( | const TDesC8 & | aString | ) | [virtual] |
Adds a Text String element.
| const TDesC8 & aString | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildURLL | ( | const TDesC8 & | aURL | ) | [virtual] |
Adds a URL element.
| const TDesC8 & aURL | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildUUIDL | ( | const TUUID & | aUUID | ) | [virtual] |
Adds a UUID element.
| const TUUID & aUUID | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildUintL | ( | const TDesC8 & | aUint | ) | [virtual] |
Adds an unsigned integer element.
| const TDesC8 & aUint | Element to add |
| IMPORT_C MSdpElementBuilder * | BuildUnknownL | ( | TUint8 | aType, |
| TUint8 | aSizeDesc, | |||
| const TDesC8 & | aData | |||
| ) | [virtual] | |||
Adds an element of any type.
| IMPORT_C MSdpElementBuilder * | EndListL | ( | ) | [virtual] |
Indicates that subsequent elements no longer belong to current DES or DEA
Building of current DES or DEA is terminated.
| IMPORT_C void | MSEB_ExtensionInterfaceL | ( | TUid | aInterface, |
| void *& | aObject | |||
| ) | ||||
Returns a null aObject if the extension is not implemented, or a pointer to another interface if it is. This virtual function allows the M- classes to be extended in future in a binary compatible way by providing a method that clients can override in future to allow extra callbacks to be made via aObject.
| TUid aInterface | UID of the interface to return |
| void *& aObject | the container for another interface as specified by aInterface |
| IMPORT_C MSdpElementBuilder * | StartListL | ( | ) | [virtual] |
Tell builder you are about to start a list
The end of the list should be indicated by a call to EndList().
