Parameters

const TMTPTypeUint128 & aR

FirstReadChunk(TPtrC8 &)

IMPORT_C TInt

FirstReadChunk

(

TPtrC8 &

aChunk

)

const [virtual]

Initiates a data read sequence on the type by providing a const pointer to the first in the sequence of data chunks that make up the type's data stream. Subsequent chunks in the sequence can be sequentially retrieved using NextReadChunk. NextReadChunk.

Parameters

TPtrC8 & aChunk

The const pointer to be set to point to the start of the first data chunk. This pointer's length is set to zero if no data chunk exists or a processing error occurs.

FirstWriteChunk(TPtr8 &)

IMPORT_C TInt

FirstWriteChunk

(

TPtr8 &

aChunk

)

[virtual]

Initiates a data write sequence on the type by providing a non-const pointer to the first in the sequence of data chunks that make up the type's data stream. Subsequent chunks in the sequence can be sequentially retrieved using NextWriteChunk. NextWriteChunk.

Parameters

TPtr8 & aChunk

The non-const pointer to be set to point to the start of the first data chunk. If successful, the pointer's Length is set to zero, and MaxLength is set to the available capacity of the data chunk. If not successful, the pointer's MaxLength is set to zero.

LowerValue()

IMPORT_C TUint64

LowerValue

(

)

const

Provides the least significant portion of the data type.

NextReadChunk(TPtrC8 &)

IMPORT_C TInt

NextReadChunk

(

TPtrC8 &

aChunk

)

const [virtual]

Continues a data read sequence on the type by providing a const pointer to the next in the sequence of data chunks that make up the type's data stream. This data read sequence should have been previously initiated by invoking FirstReadChunk. FirstReadChunk.

Parameters

TPtrC8 & aChunk

The const pointer to be set to point to the start of the next data chunk. This pointer's length is set to zero if no data chunk exists or a processing error occurs.

NextWriteChunk(TPtr8 &)

IMPORT_C TInt

NextWriteChunk

(

TPtr8 &

aChunk

)

[virtual]

Continues a data write sequence on the type by providing a non-const pointer to the next in the sequence of data chunks that make up the type's data stream. This data write sequence should have been previously initiated by invoking FirstWriteChunk. FirstReadChunk.

Parameters

TPtr8 & aChunk

The non-const pointer to be set to point to the start of the next data chunk. If successful, the pointer's Length is set to zero, and MaxLength is set to the available capacity of the data chunk. If not successful, the pointer's MaxLength is set to zero..

Set(TUint64, TUint64)

IMPORT_C void	Set	(	TUint64	aUpperValue,
			TUint64	aLowerValue
		)

Sets the data type to the specified value.

Parameters

TUint64 aUpperValue
TUint64 aLowerValue

Size()

IMPORT_C TUint64

Size

(

)

const [virtual]

Provides the size in bytes of the MTP data type.

Type()

IMPORT_C TUint

Type

(

)

const [virtual]

Provides the MTP data type identification datacode.

UpperValue()

IMPORT_C TUint64

UpperValue

(

)

const

Provides the most significant portion of type's value.
