Tests whether all the features in features are present in self.

Declaration

public static bool All(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	The Features to test against.

Returns

Type	Description
Boolean	true if all the features in features are also in self, otherwise false.

Any(Feature, Feature)

Tests whether any of the features in features are present in self.

Declaration

public static bool Any(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	The Features to test against.

Returns

Type	Description
Boolean	true if any of the features in features are also in self, otherwise false.

Cameras(Feature)

Filters just the camera-related Feature flags.

Declaration

public static Feature Cameras(this Feature self)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.

Returns

Type	Description
Feature	The camera-related Feature flags from self.

Count(Feature)

Calculates the number of enabled features in self.

Declaration

public static int Count(this Feature self)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.

Returns

Type	Description
Int32	The number of enabled Feature flags.

Intersection(Feature, Feature)

Computes the intersection of self and features (that is, the set of features present in both self and features).

Declaration

public static Feature Intersection(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	Features to intersect with self

Returns

Type	Description
Feature	The intersection of self and features (that is, the set of features common to both self and features).

LightEstimation(Feature)

Filters just the light estimation related Feature flags.

Declaration

public static Feature LightEstimation(this Feature self)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.

Returns

Type	Description
Feature	The light estimation-related Feature flags from self.

None(Feature, Feature)

Tests whether there are any common features between self and features.

Declaration

public static bool None(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	The Features to test against.

Returns

Type	Description
Boolean	true if none of the features in self are in features, otherwise false.

SetDifference(Feature, Feature)

Computes the set difference (that is, removes all flags in features from self).

Declaration

public static Feature SetDifference(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	Features to remove from self

Returns

Type	Description
Feature	The set difference of self and features (that is, all members of self which do not belong to features).

SetEnabled(Feature, Feature, Boolean)

Sets or removes one or more Feature flags.

Declaration

public static Feature SetEnabled(this Feature self, Feature feature, bool enabled)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	feature	The Feature(s) to set or remove.
Boolean	enabled	If true, the flag(s) in feature will be set. If false, it/they will be removed.

Returns

Type	Description
Feature	self with the Feature(s) set or removed according to the value of enabled.

SymmetricDifference(Feature, Feature)

Computes the symmetric difference (that is, the set of all features that belong to exactly one of self and features, present in one but not both).

Declaration

public static Feature SymmetricDifference(this Feature self, Feature features)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	Features with which to compute the symmetric difference against self

Returns

Type	Description
Feature	The symmetric difference of self and features (that is, the features that belong to self or features, but not both).

ToStringList(Feature, String)

Generates a single string representing the list of enabled features separated by separator, or a comma if not specified.

Declaration

public static string ToStringList(this Feature features, string separator = ", ")

Parameters

Type	Name	Description
Feature	features	The Feature being extended.
String	separator	The string separator to insert between elements of the list, or ", " if omitted.

Returns

Type	Description
String	A string of Features separated by separator. If none of the features are enabled, returns "(None)".

Remarks

This method makes several heap allocations, generating garbage. It is intended for debugging purposes and should not be called frequently in a production application.

TrackingModes(Feature)

Declaration

public static Feature TrackingModes(this Feature self)

Parameters

Type	Name	Description
Feature	self	The Feature being extended.

Returns

Type	Description
Feature	The tracking-related Feature flags from self.

Parameters

Type	Name	Description
Feature	self	The Feature being extended.
Feature	features	Features to union with self

Returns

Type	Description
