Member Enumerations Documentation

Enum TElementId

MTP object meta-data element identifiers.

Enumerators

EDataProviderId = 0	The ID of the data provider responsible for the data object. This element is of type TUint.
EFormatCode = 1	The object format code. This element is of type TUint.
EFormatSubCode = 2	The object format sub-code. Currently this field is ignored unless the EFormatCode contains a value of EMTPFormatCodeAssociation, in which case this field should the specify the MTP association type code. This element is of type TUint.
EHandle = 3	The object handle. This element is of type TUint.
EModes = 4	The set of MTP operational modes in which the object is visible and will be enumerated to a connected MTP Initiator. The MTP operational modes are represented as a set of TMTPOperationalMode bit flags. This element is of type TUint
EParentHandle = 5	The parent object handle. This element is of type TUint.
EStorageId = 6	The MTP storage ID of the storage on which the data object resides. This element is of type TUint.
EStorageVolumeId = 7	The MTP storage ID of the storage on which the data object resides. This element is of type TUint.
ESuid = 8	The data object's System Unique IDentifier (SUID). This element is of type TDesC&.
EUserRating = 9	The data object's user rating This element is of type TUint.
EBuyNow = 10	The data object's BuyNow flag This element is of type TUint.
EPlayCount = 11	The data object's Played flag This element is of type TUint.
EIdentifier = 12	The data Objects Identifier as in HandleStore table This element is of type TUint.
ENonConsumable = 13	The id related to ParentHandle This element is of type TUint. The flag, used in object modification, indicates if the modified object should be reported to initiator This element is of type TUint.
EObjectMetaDataUpdate = 14
EName = 15
ENumElements	The number of elements.
