AppendL(const TAiwGenericParam &)

IMPORT_C void AppendL ( const TAiwGenericParam & aParam )

Appends a parameter to this list.

Parameters

const TAiwGenericParam & aParam The parameter to append to this list. This object takes an own copy of the data in aParam.

AppendL(const CAiwGenericParamList &)

IMPORT_C void AppendL ( const CAiwGenericParamList & aList )

Copies the given list and appends it to end of this list.

Since
Series 60 2.8

Parameters

const CAiwGenericParamList & aList A list to be copied and appended.

AppendL(RReadStream &)

void AppendL ( RReadStream & aReadStream ) [private]

Appends parameters to this list from aStream.

Parameters

RReadStream & aReadStream

ConstructL()

void ConstructL ( ) [private]

Count()

IMPORT_C TInt Count ( ) const

Returns the number of parameters in the list.

Count(TGenericParamId, TVariantTypeId)

IMPORT_C TInt Count ( TGenericParamId aSemanticId,
TVariantTypeId aDataType = EVariantTypeAny
) const

Returns the number of the parameters in the list by semantic id and datatype.

Parameters

TGenericParamId aSemanticId The semantic ID of the parameter.
TVariantTypeId aDataType = EVariantTypeAny The type id of data. Default is any type.

ExternalizeL(RWriteStream &)

IMPORT_C void ExternalizeL ( RWriteStream & aStream ) const

Externalizes this parameter list to a stream.

NewL(RReadStream& aStream) NewLC(RReadStream& aStream)

Parameters

RWriteStream & aStream The stream.

FindFirst(TInt &, TGenericParamId, TVariantTypeId)

IMPORT_C const TAiwGenericParam * FindFirst ( TInt & aIndex,
TGenericParamId aSemanticId,
TVariantTypeId aDataType = EVariantTypeAny
) const

Returns the first item matching the given semantic ID.

Parameters

TInt & aIndex Position in which to start searching. On return it contains the position of the found parameter. It is set to KErrNotFound, if no matching items were found.
TGenericParamId aSemanticId The semantic ID of the parameter.
TVariantTypeId aDataType = EVariantTypeAny The type id of data. Default is any type.

FindNext(TInt &, TGenericParamId, TVariantTypeId)

IMPORT_C const TAiwGenericParam * FindNext ( TInt & aIndex,
TGenericParamId aSemanticId,
TVariantTypeId aDataType = EVariantTypeAny
) const

Returns the next item matching the given semantic ID.

Parameters

TInt & aIndex Position after which to start searching. On return it contains the position of the found parameter. It is set to KErrNotFound, if no matching items were found.
TGenericParamId aSemanticId The semantic ID of the parameter.
TVariantTypeId aDataType = EVariantTypeAny The type id of data. Default is any type.

InternalizeL(RReadStream &)

IMPORT_C void InternalizeL ( RReadStream & aStream )

Internalizes the parameter list from a stream.

Since
Series60 2.8

Parameters

RReadStream & aStream The stream.

NewL()

IMPORT_C CAiwGenericParamList * NewL ( ) [static]

Creates an instance of this class.

NewL(RReadStream &)

IMPORT_C CAiwGenericParamList * NewL ( RReadStream & aReadStream ) [static]

Creates an instance of this class.

Parameters

RReadStream & aReadStream A stream to initialize this parameter list from.

NewLC()

IMPORT_C CAiwGenericParamList * NewLC ( ) [static]

Creates an instance of this class. Leaves the created instance on the cleanup stack.

NewLC(RReadStream &)

IMPORT_C CAiwGenericParamList * NewLC ( RReadStream & aReadStream ) [static]

Creates an instance of this class. Leaves the created instance on the cleanup stack.

Parameters

RReadStream & aReadStream A stream to initialize this parameter list from.

PackForServerL(TIpcArgs &)

IMPORT_C HBufC8 * PackForServerL ( TIpcArgs & aArgs )

Parameters

TIpcArgs & aArgs Inter process call arguments.

Remove(TInt)

IMPORT_C TBool Remove ( TInt aSemanticId )

Removes the first found item with given semantic id from the list.

Parameters

TInt aSemanticId Semantic id for the item to be removed.

Reset()

IMPORT_C void Reset ( )

Deletes all parameters in the list and resets the list.

Size()

IMPORT_C TInt Size ( ) const

Returns the externalized size of the parameter list in bytes.

UnpackFromClientL(const RMessage2 &)

IMPORT_C void UnpackFromClientL ( const RMessage2 & aArgs )

Unpacks the list from client message structure.

Since
Series60 3.0

Parameters

const RMessage2 & aArgs The list to be unpacked.

operator[](TInt)

IMPORT_C const TAiwGenericParam & operator[] ( TInt aIndex ) const

Returns a parameter from this list.

Pre-condition
aIndex>=0 && aIndex< Count()

Parameters

TInt aIndex Index of the parameter.
