31 class DEMMCPartitionInfo : public DBase
33 * Base Abstract class for classes that define a partitioning scheme for Embedded MMC devices
41 * Initialise the Partition Object.
43 * Called as part of the creation process for the MMC Media driver.
45 * Initialisation can include activities such as Memory structure allocation and
46 * creation of any required driver session/handles.
48 * @param aDriver Owning DMediaDriver class
49 * @return KErrNone if successful, standard error code otherwise.
51 virtual TInt Initialise(DMediaDriver* aDriver) =0;
54 * Read the partition information for the media.
56 * Called as a child function of the PartitionInfo() method.
58 * @see DMmcMediaDriverFlash::PartitionInfo()
60 * @param anInfo An object that, on successful return, contains the partition information.
61 * @return KErrNone if successful, standard error code otherwise.
63 virtual TInt PartitionInfo(TPartitionInfo& anInfo, const TMMCCallBack& aCallBack) =0;
66 * Returns partition specific drive capability attributes.
68 * Called as a child function of the Caps() method.
70 * @see DMmcMediaDriverFlash::Caps()
72 * @param aDrive Local drive to be queried.
73 * @param aInfo Media drive capability object to be populated.
74 * @return KErrNone if successful, standard error code otherwise.
76 virtual TInt PartitionCaps(TLocDrv& aDrive, TDes8& aInfo) =0;
80 * Factory Method that returns an instance of a DEMMCPartitionInfo class.
82 * @return Newly created DEMMCPartitionInfo object.
