) const

Parameters

TResourceReader & aReader a reader
TInt aResourceId a resource key

DirectionalityL(const TDesC &, TBool *)

TBidiText::TDirectionality DirectionalityL ( const TDesC & aText,
TBool * aFound
) [private]

Parameters

const TDesC & aText
TBool * aFound

FormatStringL(const TDesC &, const TDesC &, const TDesC &, TBidiText::TDirectionality)

HBufC * FormatStringL ( const TDesC & aSource,
const TDesC & aKey,
const TDesC & aSubs,
TBidiText::TDirectionality aDir
) [private]

Finds the keystring from the source string and replaces it with the replacement string.

Parameters

const TDesC & aSource
const TDesC & aKey
const TDesC & aSubs
TBidiText::TDirectionality aDir

FormatStringL(const TDesC &, const TDesC &, const TDesC &, TBidiText::TDirectionality, TInt &, TInt)

HBufC * FormatStringL ( const TDesC & aSource,
const TDesC & aKey,
const TDesC & aSubs,
TBidiText::TDirectionality aDirectionality,
TInt & aParamCount,
TInt aSubCount
) [private]

Finds the keystring from the source string and replaces it with the replacement string.

Parameters
