TPositionQualityItem

(

)

TInt	Compare	(	const TPositionQualityItem &	aItem,
			TResult &	aComparison
		)	const

Compare method

compare method Compare method

Parameter	Description
aItem	The item that we want to compare against ourself.
aComparison	Set by this function to whether or not the TPositionQualityItem provided is better or worse than this TPositionQualityItem.

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

Gets position quality

Parameter	Description
aDataType	The datatype of the data to be fetched.
aData	A pointer to the data to be written into.
aSizeOfData	The size of the data object to be copied.

Returns: KErrArgument if there is a mismatch in the datatype between setting and getting. KErrNone if successful.

TBool

IsDefined

(

)

const

Whether or not this element has a defined state

Returns: Whether or not this element has a state of EUndefined.

Sets Position Quality

Sets position quality

Parameter	Description
aDataType	The datatype of the data to be set in the array.
aValuePreference	Whether greater or lower values indicate 'better'.
aData	A pointer to the data to be read from.
aSizeOfData	The size of the data object to be copied.
