ReferencesLC(const TMTPTypeUint32 &)

CMTPTypeArray * ReferencesLC ( const TMTPTypeUint32 & aFromHandle ) const
Provides an MTP array of the target object handles which are referenced by the specified source object handle. A pointer to the MTP array is placed on the cleanup stack.
leave
One of the system wide error codes, if a processing failure occurs.

Parameters

const TMTPTypeUint32 & aFromHandle The MTP object handle of the source object from which the references originate.

ReferencesLC(const TDesC &)

CDesCArray * ReferencesLC ( const TDesC & aParentSuid ) const
Provides an SUID array of the target object SUIDs which are referenced by the specified source object SUID. A pointer to the SUID array is placed on the cleanup stack.
leave
One of the system wide error codes, if a processing failure occurs.

Parameters

const TDesC & aParentSuid

RemoveReferencesL(TUint)

void RemoveReferencesL ( TUint aHandle )

void RemoveReferencesL ( const TDesC & aSuid )
Removes all object reference links in which the specified SUID represents either the source or target reference object.
leave
One of the system wide error codes, if a processing failure occurs.

Parameters

const TDesC & aSuid The object SUID.

SetReferenceL(const TDesC &, const TDesC &)

void SetReferenceL ( const TDesC & aFromSuid,
const TDesC & aToSuid
)
Creates an abstract reference linkage between the specified source and target object SUIDs.
leave
One of the system wide error codes, if a processing failure occurs.

Parameters

const TDesC & aFromSuid The SUID of the source object from which the reference originates. param aToSuid The SUID of the target object to which the reference is made.

TUint aToHandles
) [private]
Set reference on the object identified by aFromIdentifier
leave
One of the system wide error codes, if a processing failure occurs.

Parameters

leave
One of the system wide error codes, if a processing failure occurs.

Parameters

const TDesC & aParentSuid
const CDesCArray & aToSuids The reference target MTP object SUID array.

SetReferencesL(const TMTPTypeUint32 &, const CMTPTypeArray &)
