			TFileName &	aTempFileName,
			RResourceFile &	aResourceFile,
			HBufC8 *&	aResource
		)	[private]

given a pdr file list all the models it contains in the model array

Parameters

TInt aFileIndex
TParse & aParser
TFileName & aNameOfLoadedResourceFile
TFileName & aTempFileName
RResourceFile & aResourceFile
HBufC8 *& aResource

ModelCount()

IMPORT_C TInt

ModelCount

(

)

const [virtual]

Gets the number of printer models in the printer model list.

NewL()

IMPORT_C CPdrModelList *

NewL

(

)

[static]

Constructs, and returns a pointer to a new instance of the printer model list interface.

NewPathBufL(const TFileEntry &)

HBufC *

NewPathBufL

(

const TFileEntry &

aFileEntry

)

[private]

Create a buf of the right length and... set its contents to the full filename of model aModel

Parameters

const TFileEntry & aFileEntry

ScanDirectoryL(TInt)

void

ScanDirectoryL

(

TInt

aDirIndex

)

[private]

Scans the given directory, parsing all files found If a file is of the correct type it is appended to the file list

Parameters

TInt aDirIndex

ScanForModelsL()

IMPORT_C CPrinterModelList *

ScanForModelsL

(

)

Scans through through the list of directories for all .pdr files and generates a list of printer models.

UidToNum(TUid)

IMPORT_C TInt

UidToNum

(

TUid

aModelUid

)

const [virtual]

Gets a printer model's index within the model list from its UID.

Parameters

TUid aModelUid

The UID of the printer model.

operator[](TInt)

IMPORT_C const TPrinterModelEntry

operator[]

(

TInt

anIndex

)

[virtual]

Gets printer model name.

This is the name of the printer model at the specified index within the list of printer models.

Parameters

TInt anIndex

The index of the printer model within the array of printer models. Note that this number must be between zero and ModelCount().
