Member Functions Documentation

AddAttributeL(TInt, const TDesC &)

void	AddAttributeL	(	TInt	aAttribute,
			const TDesC &	aValue
		)

Insert an attribute. This attribute should be applied to the enclosing entity (Feed, Item, or Enclosure).

Since: 3.1

Parameters

TInt aAttribute	The attribute's id.
const TDesC & aValue	The attribute's value.

AddAttributeL(TInt, TInt)

void	AddAttributeL	(	TInt	aAttribute,
			TInt	aValue
		)

Insert an attribute. This attribute should be applied to the enclosing entity (Feed, Item, or Enclosure).

Since: 3.1

Parameters

TInt aAttribute	The attribute's id.
TInt aValue	The attribute's value.

AppendStringTableChunkL(const TDesC8 &)

void

AppendStringTableChunkL

(

const TDesC8 &

aChunk

)

Append a chunk of "string-table" values to the feed.

Since: 3.1

Parameters

const TDesC8 & aChunk

A string chunk.

AppendTokenChunkL(const TDesC8 &)

void

AppendTokenChunkL

(

const TDesC8 &

aChunk

)

Append a chunk of "token" values to the feed.

Since: 3.1

Parameters

const TDesC8 & aChunk

A token chunk.

BaseConstructL()

void

BaseConstructL

(

)

[protected]

By default Symbian 2nd phase constructor is private.

ExtractAttributeValue(TUint &, TPtrC &)

void	ExtractAttributeValue	(	TUint &	aAttribute,
			TPtrC &	aValue
		)	const

Upon completion aValue wraps the current attribute value. This method must only be called when the call to NextToken returns EPackedTokenAttribute.

Since: 3.1

Parameters

TUint & aAttribute	The attribute.
TPtrC & aValue	The attribute value.

HasNextToken()

TBool

HasNextToken

(

)

const

Determine if there is a next token.

Since: 3.1

InsertTokenL(TUint)

void

InsertTokenL

(

TUint

aToken

)

[protected]

Insert a token.

Since: 3.1

Parameters

TUint aToken

The token.

NextToken()

TUint
