Member Functions Documentation

CategoriesCount()

IMPORT_C TInt

CategoriesCount

(

)

Returns total amount of landmark categories in the database.

CategoryManager()

CPosLmCategoryManager &

CategoryManager

(

)

[pure virtual]

Returns reference to category manager instance for this database.

GetExtension(TUid)

void *

GetExtension

(

TUid

aExtensionUid

)

[protected, pure virtual]

Returns pointer to extension interface. Type of the requested extension interface is supplied by caller in aExtensionId.

Ownership of returned object is not transferred to caller, it is kept by implementation.

Parameters

TUid aExtensionUid

Type of requested extension

LandmarksCount()

IMPORT_C TInt

LandmarksCount

(

)

Returns total amount of landmarks in the database.

OpenL()

IMPORT_C CPosLandmarkDatabaseExtended *

OpenL

(

)

[static]

Opens the default landmark database.

This method is the same as CPosLandmarkDatabase::OpenL() .

The client takes ownership of the returned database handle.

The database may have to be initialized before it can be used, see IsInitializingNeeded and InitializeL .

This function requires ReadUserData capability.

leave: KErrNotSupported This extended interface is not supported for default database.

CPosLandmarkDatabase::OpenL()

OpenL(const TDesC &)

IMPORT_C CPosLandmarkDatabaseExtended *

OpenL

(

const TDesC &

aDatabaseUri

)

[static]

Opens a specific landmark database.

This method is the same as CPosLandmarkDatabase::OpenL(const TDesC&) .

The client refers to a database by URI. The URI consists of a protocol specifier and the database location: "protocol://location". If the client does not specify a protocol, "file://" will be assumed.

For local landmark databases, the URI consists of the drive and the database file name, e.g. "c:landmarks.ldb". The path cannot be specified by the client. The extension of the database file name must be "ldb" otherwise the client will get the error KErrArgument.

If the client specifies a local database and does not specify the drive letter, e.g. "landmarks.ldb", default database drive will be assumed.

The client takes ownership of the returned database handle.

The database may have to be initialized before it can be used, see IsInitializingNeeded and InitializeL .

This function requires ReadUserData capability.
