Member Functions Documentation
AppendSupportedValueL(const MMTPType &)
| IMPORT_C void | AppendSupportedValueL | ( | const MMTPType & | aValue | ) | |
Appends the specified value to the set of supported enumeration values.
- leave
- One of the system wide error codes, if unsuccessful.
- panic
- MTPDataTypes 3, if the source value type does not match the property data type.
Parameters
| const MMTPType & aValue | The enumeration value to append. |
AppendValueChunkL()
| void | AppendValueChunkL | ( | ) | [private] |
CommitRequired()
| IMPORT_C TBool | CommitRequired | ( | ) | const [virtual] |
ConstructL()
| void | ConstructL | ( | ) | [private] |
ElementInfo(TInt)
Provides the TElementInfo data for the specified element.
Parameters
| TInt aElementId | The identifier of the requested element. |
FirstWriteChunk(TPtr8 &)
| IMPORT_C TInt | FirstWriteChunk | ( | TPtr8 & | aChunk | ) | [virtual] |
NewL(TUint)
MTP DevicePropDesc Enumeration FORM dataset factory method. This method is used to create an empty MTP DevicePropDesc FORM dataset of the specified Datatype.
- leave
- One of the system wide error codes, if unsuccessful.
Parameters
| TUint aDataType | The data type identifier datacode of the dataset. |
NewLC(TUint)
MTP DevicePropDesc Enumeration FORM dataset factory method. This method is used to create an empty MTP DevicePropDesc FORM dataset of the specified Datatype. A pointer to the data type is placed on the cleanup stack.
- leave
- One of the system wide error codes, if unsuccessful.
Parameters
| TUint aDataType | The data type identifier datacode of the dataset. |
NextWriteChunk(TPtr8 &)
| IMPORT_C TInt | NextWriteChunk | ( | TPtr8 & | aChunk | ) | [virtual] |
NumberOfValues()
| IMPORT_C TUint16 | NumberOfValues | ( | ) | const |
Provides the NumberOfValues element value.
SupportedValueL(TUint, MMTPType &)
| IMPORT_C void | SupportedValueL | ( | TUint | aIndex, |
| | MMTPType & | aValue |
| | ) | const |
Provides the SupportedValue element at the specified index.
- leave
- One of the system wide error codes, if unsuccessful.
- panic
- MTPDataTypes 3, if the target value type does not match the property data type.
Parameters
| TUint aIndex | The index of the required value. |
| MMTPType & aValue | On successful completion, the requested value. |
Type()
| IMPORT_C TUint | Type | ( | ) | const [virtual] |
ValidateChunkCount()
|
TInt
| ValidateChunkCount | ( | ) | const [private, virtual] |
Validates that the number of chunks making up the compound type is valid. This method is invoked on variable length compound types by the default Valid implementation. Valid KVariableChunkCount
