[private]

Symbian second-phase constructor

Get(TInt, TDes &)

IMPORT_C TInt	Get	(	TInt	aParamID,
			TDes &	aValue
		)

Get the value of an identified parameter stored in the object

Parameters

TInt aParamID	The ID of the requested parameter.
TDes & aValue	Will contain a pointer to a descriptor containing the value after a successful call. The client owns this pointer after the call.

Get(TInt, TInt &)

IMPORT_C TInt	Get	(	TInt	aParamID,
			TInt &	aValue
		)

Get the value of an identified parameter stored in the object

Parameters

TInt aParamID	The ID of the requested parameter.
TInt & aValue	Will contain the requested value converted to an integer after a successful call. If the value cannot be converted, an error will be returned.

GetBuffer(HBufC8 *&)

IMPORT_C TInt

GetBuffer

(

HBufC8 *&

aBuffer

)

Pack the stored parameters into a buffer.

Parameters

HBufC8 *& aBuffer

GetParamLength(TInt)

IMPORT_C TInt

GetParamLength

(

TInt

aParamID

)

Get the value of an identified parameter stored in the object

Parameters

TInt aParamID

The ID of the requested parameter.

NewL()

IMPORT_C CSCPParamObject *

NewL

(

)

[static]

Static constructor.

NewLC()

IMPORT_C CSCPParamObject *

NewLC

(

)

[static]

Static constructor, that leaves the pointer to the cleanup stack.

Parse(TDes8 &)

IMPORT_C TInt

Parse

(

TDes8 &

aBuffer

)

Parse the given buffer, and add its contents to the object.

Parameters

TDes8 & aBuffer

The buffer that will be parsed.

ReadFromFileL(TDesC &, RFs *)

IMPORT_C void	ReadFromFileL	(	TDesC &	aFilename,
			RFs *	aRfs = NULL
		)

Reset the content of this object and load new content from a file. Leaves with a generic status code on error.

Parameters

TDesC & aFilename	The file name to read the content from. This filename must contain a buffer returned by GetBuffer.
RFs * aRfs = NULL	An optional pointer to a connected file server session. If this pointer is not supplied a new RFs will be connected.

Reset()

IMPORT_C TInt

Reset

(

)

Reset the object and remove all parameters.

Set(TInt, TDes &)

IMPORT_C TInt	Set	(	TInt	aParamID,
			TDes &	aValue
		)

Set the value of a parameter. Will replace an existing value, or add a new one.

Parameters

TInt aParamID	The ID of the parameter.
TDes & aValue	The value to set.

Set(TInt, TInt)

IMPORT_C TInt	Set	(	TInt	aParamID,
			TInt	aValue
		)

Set the value of a parameter. Will replace an existing value, or add a new one.

Parameters

TInt aParamID	The ID of the parameter.
TInt aValue	The value to set, will be converted to a descriptor.

Unset(TInt)

IMPORT_C TInt

Unset

(

TInt

aParamID

)

Remove the identified parameter from the storage.

Parameters

TInt aParamID

The ID of the parameter to remove.

WriteToFileL(TDesC &, RFs *)

IMPORT_C void	WriteToFileL	(	TDesC &	aFilename,
			RFs *	aRfs = NULL
		)

Write the content to disk in the format returned by GetBuffer. Leaves with a generic status code on error.

Parameters

TDesC & aFilename	The name of the file to be written. An existing file will be overwritten, or a new file will be created.
RFs * aRfs = NULL	An optional pointer to a connected file server session. If this pointer is not supplied a new RFs will be connected.
