Class CSdpAttrValueList

class CSdpAttrValueList : public CSdpAttrValue, public MSdpElementBuilder;

Description

Base class for classes that specify lists of attribute data elements.

It implements the MSdpElementBuilder interface to build data elements into an attribute value.

Derivation

• MSdpElementBuilder - Constructs an attribute value, or a set of attributes, from multiple data elements
• CBase - Base class for all classes to be instantiated on the heap
• CSdpAttrValue - Base class for classes that encapsulate SDP attributes values
• CSdpAttrValueList - Base class for classes that specify lists of attribute data elements

Members

virtual IMPORT_C ~CSdpAttrValueList();

Description

Destructor.

virtual IMPORT_C void AcceptVisitorL(MSdpAttributeValueVisitor &aVisitor);

Description

Requests a call back to pass the attribute value.

This provides a simple method of enumerating each element in the list.

Parameters

virtual IMPORT_C TUint DataSize() const;

Description

Gets the size of the list.

Return value

IMPORT_C void AppendValueL(CSdpAttrValue *aValue);

Description

Add a new value onto the end on this list.

Ownership of the passed value is transferred to this list. It will be deleted when the list is destroyed.

If a leave occurs, aValue will be cleanup up automatically

Parameters

virtual IMPORT_C MSdpElementBuilder *BuildUnknownL(TUint8 aType, TUint8 aSizeDesc, const TDesC8 &aData);

Description

Adds an element of any type.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildNilL();

Description

Adds a null type element.

Return value

virtual IMPORT_C MSdpElementBuilder *BuildUintL(const TDesC8 &aUint);

Description

Adds an unsigned integer element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildIntL(const TDesC8 &aInt);

Description

Adds a signed integer element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildUUIDL(const TUUID &aUUID);

Description

Adds a UUID element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildBooleanL(TBool aBool);

Description

Adds a Boolean element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildStringL(const TDesC8 &aString);

Description

Adds a Text String element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildDESL();

Description

Adds a Data element sequence (DES).

This should be followed by a call to StartListL(), and then calls to add elements to the list.

Return value

virtual IMPORT_C MSdpElementBuilder *BuildDEAL();

Description

Adds a Data element alternative (DEA).

This should be followed by a call to StartListL(), and then calls to add elements to the list.

Return value

virtual IMPORT_C MSdpElementBuilder *StartListL();

Description

Indicates that subsequent elements added belong to a DES or DEA.

The end of the list should be indicated by a call to EndList().

Return value

virtual IMPORT_C MSdpElementBuilder *EndListL();

Description

Indicates the end of a list started by StartListL().

Return value

virtual IMPORT_C MSdpElementBuilder *BuildURLL(const TDesC8 &aString);

Description

Adds a URL element.

Parameters

Return value

virtual IMPORT_C MSdpElementBuilder *BuildEncodedL(const TDesC8 &aString);

Description

Encode an attribute value.

Parameters

Return value

protected: CArrayPtr< CSdpAttrValue > * iList;

Description

Array of attribute values contained in this CSdpAttrValueList class
