CMTPTypeInterdependentProperties Class Reference

class CMTPTypeInterdependentProperties : public CMTPTypeCompoundBase

Defines the MTP InterdependentPropDesc array element dataset. The InterdependentPropDesc array element dataset is itself an array of MTP ObjectPropDesc datasets that specifies one possible definition for the interdependent properties that are contained in that array.

Member Functions Documentation

AppendElementChunkL(CMTPTypeObjectPropDesc *)

void AppendElementChunkL ( CMTPTypeObjectPropDesc * aElement ) [private]

Parameters

CMTPTypeObjectPropDesc * aElement

AppendL(CMTPTypeObjectPropDesc *)

IMPORT_C void AppendL ( CMTPTypeObjectPropDesc * aObjectPropDesc )
Appends the specified ObjectPropDesc dataset to the InterdependentPropDesc array element array. Ownership of the specified ObjectPropDesc dataset is passed to the InterdependentPropDesc array element array.
leave
One of the system wide error codes, if unsuccessful.

Parameters

CMTPTypeObjectPropDesc * aObjectPropDesc The ObjectPropDesc dataset to append. Ownership IS transferred.

CommitChunkL(TPtr8 &)

IMPORT_C MMTPType * CommitChunkL ( TPtr8 & aChunk ) [virtual]

Parameters

TPtr8 & aChunk

CommitRequired()

IMPORT_C TBool CommitRequired ( ) const [virtual]

ConstructL()

void ConstructL ( ) [private]

ElementInfo(TInt)

const TElementInfo & ElementInfo ( TInt aElementId ) const [private, virtual]

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]

Parameters

TPtr8 & aChunk

NewL()

IMPORT_C CMTPTypeInterdependentProperties * NewL ( ) [static]
MTP InterdependentPropDesc array element dataset factory method. This method is used to create an empty MTP InterdependentPropDesc array element dataset.
leave
One of the system wide error codes, if unsuccessful.

NewLC()

IMPORT_C CMTPTypeInterdependentProperties * NewLC ( ) [static]
MTP InterdependentPropDesc array element dataset factory method. This method is used to create an empty MTP InterdependentPropDesc array element dataset. A pointer to the data type is placed on the cleanup stack.
leave
One of the system wide error codes, if unsuccessful.

NextWriteChunk(TPtr8 &)

IMPORT_C TInt NextWriteChunk ( TPtr8 & aChunk ) [virtual]

Parameters

TPtr8 & aChunk

NumberOfPropDescs()

IMPORT_C TUint32 NumberOfPropDescs ( ) const

Provides the NumberOfPropDescs element value.

ObjectPropDesc(TUint)

IMPORT_C CMTPTypeObjectPropDesc & ObjectPropDesc ( TUint aIndex ) const
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.

Type()

IMPORT_C TUint Type ( ) const [virtual]

UpdateWriteSequenceErr(TInt)

TInt UpdateWriteSequenceErr ( TInt aErr ) [private]

Parameters

TInt aErr

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
