)

[protected]

Parameters

const TLbsAssistanceDataLayoutMap * aLayout

Member Functions Documentation

FieldExists(const typename T::TFieldId &)

TBool

FieldExists

(

const typename T::TFieldId &

aFieldId

)

const [inline]

Field Exists Returns true if Data Builder Field Exists

Parameters

const typename T::TFieldId & aFieldId

id of field we are interested in

GetArrayReader(const typename T::TFieldId &, RDataReaderArrayBase &)

TInt	GetArrayReader	(	const typename T::TFieldId &	aFieldId,
			RDataReaderArrayBase &	aArrayReader
		)	const [inline]

GetArrayReader ArrayReader array reader implementation

Parameters

const typename T::TFieldId & aFieldId	id of field we are interested in
RDataReaderArrayBase & aArrayReader	reference to RDataReaderArrayBase

GetField(const typename T::TFieldId &, S &)

TInt	GetField	(	const typename T::TFieldId &	aFieldId,
			S &	aData
		)	const [inline]

Get Field GetField field exists implementation

Parameters

const typename T::TFieldId & aFieldId	index of field we are interested in
S & aData	data from reader we are interested in

GetFieldReader(const typename T::TFieldId &, RDataReader< S, RDataReaderBase > &)

TInt	GetFieldReader	(	const typename T::TFieldId &	aFieldId,
			RDataReader< S, RDataReaderBase > &	aDataReader
		)	const [inline]

Get Field Reader Get must get a RDataReader<S, RDataReaderBase>, not a RDataReader<S, RDataReaderRootBase> - hence the template as is... FieldReader implementation

Parameters

const typename T::TFieldId & aFieldId	id of field we are interested in
RDataReader< S, RDataReaderBase > & aDataReader	we are interested in
