IMPORT_C static CCnaConverterList* NewL();

Description

Allocates and constructs a CCnaConverterList.

Return value

IMPORT_C static CCnaConverterList* NewLC();

Description

Allocates and constructs a CCnaConverterList, leaving the object on the cleanup stack.

Return value

IMPORT_C ~CCnaConverterList();

Description

Destructor.

This releases all loaded converter DLLs.

IMPORT_C void Release();

Description

Legacy function, do not use.

IMPORT_C TInt CountL();

Description

Gets the total number of converters.

It can leave because it needs to rescan the disk to refresh the list of converters.

Return value

inline TInt Count();

Description

Deprecated - Use CCnaConverterList::CountL() instead. Rescan of the disk to refresh the list of converters could leave.

Return value

IMPORT_C CConverterBase* NewConverterL(TUid aUid);

Description

Locates the converter with the specified UID, loads its associated DLL and returns a pointer to it.

Parameters

Return value

IMPORT_C void UpdateL();

Description

Requests a rescan of the disk to refresh the list of converters.

IMPORT_C TUid ConvFromL(const TDataType &aMimeType);

Description

Gets the UID of the converter that converts from the specified data type.

Parameters

Return value

Description

Gets the UID of the converter that converts to a specified data type.

Parameters

Return value

IMPORT_C TUid ConverterL(const TDataType &aFrom, const TDataType &aTo);

Description

Gets the UID of the converter that converts to and from the specified data types.

Parameters

Return value

IMPORT_C void ConvFromListL(const TDataType &aMimeType, CArrayFix< SConverterInfo > *aSConverterInfoArray);

Description

Gets a list of converters that convert from a specified data type.

Parameters
