protected: IMPORT_C TPositionQualityBase();

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.

IMPORT_C TBool IsDefined(TInt aElementId) const;

Description

Returns whether an element is defined

Parameters


TInt aElementId

The element Id of that we're interested in.

Return value

TBool

TBool if defined

IMPORT_C TInt HighWaterMark() const;

Description

Returns The High Water Mark

Return value

TInt

The High Water Mark.

protected: IMPORT_C void ResetElement(TInt aElementId);

Description

Resets element

Parameters


TInt aElementId

The id of the element to be reset to a state of EUndefined. Maintains the iHighWaterMark.

protected: inline void SetElement(TInt aElementId, TPositionQualityItem::TDataType aDataType, TPositionQualityItem::TValuePreference aValuePreference, T aData);

Description

Sets the data of an element from the array of elements.

Parameters

`TPositionQualityItem::TDataType aDataType`	The datatype of the data to be fetched.
`TPositionQualityItem::TValuePreference aValuePreference`	Quality preferences
`T aData`	A pointer to the data to be written into.

protected: inline TInt GetElement(TInt aElementId, TPositionQualityItem::TDataType aDataType, T &aData) const;

Description

Gets the data of an element from the array of elements.

Parameters

`TInt aElementId`	The element Id of that we're interested in.
`TPositionQualityItem::TDataType aDataType`	The datatype of the data to be fetched.
`T &aData`	A pointer to the data to be written into.

Return value


TInt
