The feature discovery API provides methods which are used to query which features are supported in the environment.
| 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.
| Parameter | Description |
|---|---|
| aFeatures | is the wrapper class for feature array queried. |
Returns: KErrNone if status query succeeded. Otherwise one of the Symbian OS error codes
| IMPORT_C void | FeaturesSupportedL | ( | TFeatureSet & | aFeatures | ) | [static] |
Static method to query the supported status of a set of features on the device.
| Parameter | Description |
|---|---|
| aFeatures | is the wrapper class for feature array queried. |
Static method to query the supported status of a feature on the device.
DeprecatedUse IsFeatureSupportedL(TUid aFeature) instead.
| Parameter | Description |
|---|---|
| aFeature | is the feature ID of the feature that is queried. |
Returns: a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
Static method to query the supported status of a feature on the device.
| Parameter | Description |
|---|---|
| aFeature | is the feature UID of the feature that is queried. |
Returns: a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.
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.
DeprecatedUse IsSupported(TUid aFeature) instead.
| Parameter | Description |
|---|---|
| aFeature | is the feature ID of the feature that is queried. |
Returns: a TBool indicating whether the feature is supported (ETrue) or not (EFalse). If the feature does not exist, the return value is EFalse.

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