Destructor.

Member Functions Documentation

ConstructL()

void ConstructL ( ) [private]

By default Symbian OS constructor is private.

FeaturesSupported(TFeatureSet &)

IMPORT_C TInt FeaturesSupported ( TFeatureSet & aFeatures ) const

Dynamic method to query the supported status of a set of features on the device. Before calling the method an instance of the CFeatureDiscovery class need to be created by using one of the factory methods, NewL() or NewLC() . The created instance must be deleted after use.

Parameters

TFeatureSet & aFeatures is the wrapper class for feature array queried.

FeaturesSupportedL(TFeatureSet &)

IMPORT_C void FeaturesSupportedL ( TFeatureSet & aFeatures ) [static]

Static method to query the supported status of a set of features on the device.

leave
Any One of the Symbian OS system-wide error codes

Parameters

TFeatureSet & aFeatures is the wrapper class for feature array queried.

IsFeatureSupportedL(TInt)

IMPORT_C TBool IsFeatureSupportedL ( TInt aFeature ) [static]

Static method to query the supported status of a feature on the device.

Use IsFeatureSupportedL(TUid aFeature) instead.

leave
Any One of the Symbian OS system-wide error codes

Parameters

TInt aFeature is the feature ID of the feature that is queried.

IsFeatureSupportedL(TUid)

IMPORT_C TBool IsFeatureSupportedL ( TUid aFeature ) [static]

Static method to query the supported status of a feature on the device.

leave
Any One of the Symbian OS system-wide error codes

Parameters

TUid aFeature is the feature UID of the feature that is queried.

IsSupported(TInt)

IMPORT_C TBool IsSupported ( TInt aFeature ) const

Dynamic method to query the supported status of a feature on the device. Before calling the method an instance of the CFeatureDiscovery class must be created by using one of the factory methods, NewL() or NewLC() . The created instance must be deleted after use.

Use IsSupported(TUid aFeature) instead.

Parameters

TInt aFeature is the feature ID of the feature that is queried.

IsSupported(TUid)

IMPORT_C TBool IsSupported ( TUid aFeature ) const

Dynamic method to query the supported status of a feature on the device.

Before calling the method an instance of the CFeatureDiscovery class must be created by using one of the factory methods, NewL() or NewLC() . The created instance must be deleted after use.

Parameters

TUid aFeature is the feature UID of the feature that is queried.

NewL()

IMPORT_C CFeatureDiscovery * NewL ( ) [static]

This is a two-phase constructor method that is used to create a new instance of the CFeatureDiscovery class.

leave
Any One of the Symbian OS system-wide error codes

NewLC()

IMPORT_C CFeatureDiscovery * NewLC ( ) [static]

This is a two-phase constructor method that is used to create a new instance of the CFeatureDiscovery class. This method leaves the instance of the object on the cleanup stack.

leave
Any One of the Symbian OS system-wide error codes
