| 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.
KErrNone if status query succeeded. Otherwise one of the Symbian OS error codes
| TFeatureSet & aFeatures | is the wrapper class for feature array queried. |
| 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
| TFeatureSet & aFeatures | is the wrapper class for feature array queried. |
| 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.
a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
leave
Any One of the Symbian OS system-wide error codes
| TInt aFeature | is the feature ID of the feature that is queried. |
| IMPORT_C TBool | IsFeatureSupportedL | ( | TUid | aFeature | ) | [static] |
Static method to query the supported status of a feature on the device.
a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
leave
Any One of the Symbian OS system-wide error codes
| TUid aFeature | is the feature UID of the feature that is queried. |
| 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.
a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
| TInt aFeature | is the feature ID of the feature that is queried. |
| IMPORT_C TBool | IsSupported | ( | TUid | aFeature | ) | const |
Dynamic method to query the supported status of a feature on the device.

a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
| TUid aFeature | is the feature UID of the feature that is queried. |
| IMPORT_C CFeatureDiscovery * | NewL | ( | ) | [static] |
This is a two-phase constructor method that is used to create a new instance of the CFeatureDiscovery class.
a pointer to a new instance of the CFeatureDiscovery class.

Any One of the Symbian OS system-wide error codes
| 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.
a pointer to a new instance of the CFeatureDiscovery class.
