TMTPTypeIntBase Class Reference
| class TMTPTypeIntBase : public MMTPType |
Defines the MTP signed integer data type base class for 8 to 32-bit integers. This class is intended for derivation.
Constructor & Destructor Documentation

| IMPORT_C | TMTPTypeIntBase | ( | TInt | aData, |
| | TUint | aSize, |
| | TInt | aType |
| | ) | [protected] |
Parameters
| TInt aData | The INT data with which the type is to be initialised. |

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. |
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.. |
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.
