Constructor & Destructor Documentation

TMTPTypeInt128()

IMPORT_C TMTPTypeInt128 ( )

Default constructor.

TMTPTypeInt128(const TPtrC8 &)

IMPORT_C TMTPTypeInt128 ( const TPtrC8 & aData )

Conversion constructor.

Parameters

const TPtrC8 & aData

Member Functions Documentation

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(TInt64, TUint64)

IMPORT_C void Set ( TInt64 aUpperValue,
TUint64 aLowerValue
)

Sets the data type to the specified value.

Parameters

TInt64 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 TInt64 UpperValue ( ) const

Provides the most significant portion of type's value.
