Constructor & Destructor Documentation

TCapabilitySet()

TCapabilitySet()[inline]

Default constructor. This leaves the set in an undefned state.

TCapabilitySet(TCapability)

TCapabilitySet(TCapabilityaCapability)[inline]

Construct a set consisting of a single capability.

Parameters

TCapability aCapabilityThe single capability

TCapabilitySet(TCapability, TCapability)

IMPORT_CTCapabilitySet(TCapabilityaCapability1,
TCapabilityaCapability2
)

Construct a set consisting of two capabilities.

Parameters

TCapability aCapability1The first capability.

Member Functions Documentation

AddCapability(TCapability)

IMPORT_C voidAddCapability(TCapabilityaCapability)

Add a single capability to the set. If the capability is not supported by this OS version then it is not added and the set is left unchanged. TCapabilitySet::SetAllSupported()

Parameters

TCapability aCapabilityCapability to add.

HasCapabilities(const TCapabilitySet &)

IMPORT_C TBoolHasCapabilities(const TCapabilitySet &aCapabilities)const

Test if all the capabilities in a given set are present in this set

Parameters

const TCapabilitySet & aCapabilitiesThe capability set to test

HasCapability(TCapability)

IMPORT_C TBoolHasCapability(TCapabilityaCapability)const

Test if a single capability is present in the set. The capability ECapability_None is always treated as being present.

Parameters

TCapability aCapabilityThe capability to test

Intersection(const TCapabilitySet &)

IMPORT_C voidIntersection(const TCapabilitySet &aCapabilities)

Perform an intersection of this capability set with another. The result replaces the content of 'this'.

Parameters

const TCapabilitySet & aCapabilitiesA capability set

NotEmpty()

TBool NotEmpty()const

Remove(const TCapabilitySet &)

IMPORT_C voidRemove(const TCapabilitySet &aCapabilities)

Remove a set of capabilities from this set.

Parameters

const TCapabilitySet & aCapabilitiesThe set of capabilities to remove

RemoveCapability(TCapability)

IMPORT_C voidRemoveCapability(TCapabilityaCapability)

Remove a single capability from the set, if it is present.

Parameters

TCapability aCapabilityCapability to remove.

Set(TCapability)

voidSet(TCapabilityaCapability)[inline]

Make this set consist of a single capability.

Parameters

TCapability aCapabilityThe single capability.

Set(TCapability, TCapability)

voidSet(TCapabilityaCapability1,
TCapabilityaCapability2
)[inline]

Make this set consist of two capabilities.

Parameters

TCapability aCapability1The first capability.
TCapability aCapability2The second capability.

SetAllSupported()

IMPORT_C voidSetAllSupported()

Make this set consist of all capabilities supported by this OS version.

SetDisabled()

IMPORT_C voidSetDisabled()

Make this set consist of the capabilities which are disabled on this platform.

SetEmpty()

IMPORT_C voidSetEmpty()

Make this set empty. I.e. Containing no capabilities.

Union(const TCapabilitySet &)

IMPORT_C voidUnion(const TCapabilitySet &aCapabilities)

Perform a union of this capability set with another. The result replaces the content of 'this'.

Parameters

const TCapabilitySet & aCapabilitiesA cpability set
