Description

Default constructor for TPositionQualityBase

IMPORT_C TInt Compare(const TPositionQualityBase &aPositionQuality, TInt aElementToCompare, TPositionQualityItem::TResult &aComparison) const;

Description

Compares a specified element of another TPositionQualityBase object to this TPositionQualityBase.

Parameters

const TPositionQualityBase &aPositionQuality The position quality to compare against this position quality. TInt aElementToCompare The element number that we want to compare. TPositionQualityItem::TResult &aComparison Set by this function to whether or not the TPositionQualityBase provided is better or worse than this TPositionQualityBase.

Return value

TInt KErrNone if comparison was successful. KErrArgument if there is a mismatch of the datatypes of the value preference.
