CMTPTypeInterdependentPropDesc Class Reference
| class CMTPTypeInterdependentPropDesc : public CMTPTypeCompoundBase |
Defines the MTP InterdependentPropDesc dataset. The InterdependentPropDesc implements an array of MTP ObjectPropDesc arrays, each describing a permissable collection of ranges. Each array of MTP ObjectPropDesc datasets gives one possible definition for the interdependent properties that are contained in that array; properties not found in that array are constrained only by the usual ObjectPropDesc datasets. This dataset is used in the GetInterdependentPropDesc request.

Member Functions Documentation
AppendElementChunkL(CMTPTypeInterdependentProperties *)
AppendL(CMTPTypeInterdependentProperties *)
Appends the specified InterdependentPropDesc value quadruple to the InterdependentPropDesc. Ownership of the specified InterdependentPropDesc value quadruple is passed to the InterdependentPropDesc.
- leave
- One of the system wide error codes, if unsuccessful.
CommitRequired()

ConstructL()
| void | ConstructL | ( | ) | [private] |
ElementInfo(TInt)
Provides the TElementInfo data for the specified element.
Parameters

InterdependentProperties(TUint)
Provides a non-const reference to the InterdependentPropDesc value quadruple element at the specified index.
- leave
- One of the system wide error codes, if unsuccessful.
Parameters
| TUint aIndex | The index of the required element. |
NewL()
MTP InterdependentPropDesc dataset factory method. This method is used to create an empty MTP InterdependentPropDesc dataset.
- leave
- One of the system wide error codes, if unsuccessful.
NewLC()
MTP InterdependentPropDesc dataset factory method. This method is used to create an empty MTP InterdependentPropDesc dataset. A pointer to the data type is placed on the cleanup stack.
- leave
- One of the system wide error codes, if unsuccessful.
