Parameters

HBufC8 &aBuffer A reference to the buffer with the data to process

virtual void SetStatus(TInt aStatusCode=KErrNone)=0;

Parameters

TInt aStatusCode The status of the data provider

virtual void SetDocumentTypeL(const TDesC &aDataType)=0;

Description

Intended Usage : The request to construct a CDataHandler to process data of aDataType, where aDataType is a string to match against some plugins declared data handling ability.

Parameters

const TDesC &aDataType A reference to a descriptor with the data type

virtual void SetDocumentTypeL(const TDesC &aDataType, const TDesC &aContentType)=0;

Description

Intended Usage : The request to construct a CDataHandler for aDataType with non default document encoding where aDataType is a string to match against some plugins declared data handling ability.

Parameters

const TDesC &aDataType A reference to a descriptor with the data type const TDesC &aContentType A reference to a descriptor with the content type

virtual void SetDataExpected(TInt aAmountExpected)=0;

Description

Intended Usage : The report of how many bytes of data is expected to be passed to ProcessDataL, enabling age reporting capabilities.

Parameters

TInt aAmountExpected An integer value of the expected amount

virtual void SetBaseUriL(const TDesC *aBaseUri)=0;

Description

Intended Usage : Set the URI that the DataProvider considers the base URI for the current data.

Parameters

const TDesC *aBaseUri A const pointer to the uri
