IMPORT_C static CSdpSearchPattern* NewL();

Description

Allocates and constructs a new CSdpSearchPattern object.

Return value

CSdpSearchPattern * New CSdpSearchPattern object

IMPORT_C void ConstructL();

Description

Allocates a new UUID array.

IMPORT_C ~CSdpSearchPattern();

Description

Destructor

Destroys the UUID array.

IMPORT_C TInt AddL(const TUUID &aUUID);

Description

Adds a UID to the list.

Parameters

const TUUID &aUUID UUID to add

Return value

TInt Position in the list that the UUID is inserted at, or KErrAlreadyExists if it's already in the list

IMPORT_C TInt Remove(const TUUID &aUUID);

Description

Removes a UUID from the list.

Parameters

const TUUID &aUUID UUID to remove

Return value

TInt Position in the list of the UUID, or KErrNotFound if it's not in the list

IMPORT_C TInt Find(const TUUID &aUUID, TInt &aPos) const;

Description

Gets the position of the specified UUID in the list.

Parameters

const TUUID &aUUID UUID to find TInt &aPos Position of the UUID if it is in the list, otherwise the position where it would be inserted

Return value

TInt 0 if aUUID is found, otherwise non-zero

IMPORT_C TInt Count() const;

Description

Gets the number of UUIDs in the list.

Return value

TInt Number of UUIDs in the list

IMPORT_C const TUUID At(TInt anIndex) const;

Description

Gets the UUID at the specified position in the list.

Parameters

TInt anIndex Position of the UUID to get

Return value

const TUUID UUID at specified position

IMPORT_C void Reset();

Description

Removes all UUIDs from the list.

IMPORT_C TBool IsEmpty();

Description

Tests if the list is empty.

Return value

TBool True if the list is empty

private: virtual MSdpElementBuilder* BuildUUIDL(const TUUID &aUUID);

Description

Adds a UUID element.

Parameters

const TUUID &aUUID Element to add

Return value

MSdpElementBuilder * Builder with added element

private: virtual MSdpElementBuilder* BuildDESL();

Description

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 CSdpSearchPattern::StartListL(), and then calls to add elements to the list.

Return value

MSdpElementBuilder * Attribute value with added element

private: virtual 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

MSdpElementBuilder * Builder

private: virtual MSdpElementBuilder* EndListL();

Description

Indicates that subsequent elements no longer belong to current DES or DEA

Building of current DES or DEA is terminated.

Return value

MSdpElementBuilder * Builder
