CContactViewRangeBase Class Reference

class CContactViewRangeBase : public CBase

The abstract base class for all contact view range classes.

Range classes are used by contact sub views to specify the upper and lower range boundaries and for searching their underlying view.

Member Functions Documentation

ConstructL()

void ConstructL ( ) [protected]

Called by derived classes to set the collation method iCollateMethod to be the standard collation method for the current locale.

FindIndexL(const TDesC &, TCriteria)

TInt FindIndexL ( const TDesC & aMatch,
TCriteria aCriteria
) const [protected]

Called by implementations of SetL() to search the sub view's underlying view for the index of the first item whose field content matches aMatch, using the specified search criteria.

Parameters

const TDesC & aMatch The text to search for.
TCriteria aCriteria The search criteria.

HighIndex()

TInt HighIndex ( ) const [inline]

Gets the index into the sub view's underlying view of the item at the top of the range.

IndicesValid()

IMPORT_C TBool IndicesValid ( ) const

Tests whether the lower and upper indexes are valid, i.e. not KErrNotFound.

LowIndex()

TInt LowIndex ( ) const [inline]

Gets the index into the sub view's underlying view of the item at the bottom of the range.

MatchesCriteriaL(TCriteria, const TDesC &, TInt)

TBool MatchesCriteriaL ( TCriteria aCriteria,
const TDesC & aMatch,
TInt aIndex
) const [protected]

Parameters

TCriteria aCriteria
const TDesC & aMatch
TInt aIndex

SetL()

void SetL ( ) [pure virtual]

Sets the iLow and iHigh members.

ValidateIndices()

void ValidateIndices ( ) [protected]

Called by derived classes to validate the upper and lower indexes (iLow and iHigh).

If either index is KErrNotFound, or iLow is greater than iHigh, then both are set to KErrNotFound.

Member Data Documentation

TCollationMethod * iCollateMethod

TCollationMethod * iCollateMethod [protected]

The collation method used to sort the strings.

By default, this is the standard collation method for the current locale.

TInt iHigh

TInt iHigh [protected]

The index into the sub view's underlying view of the item at the upper limit of the range.

TInt iLow

TInt iLow [protected]

The index into the sub view's underlying view of the item at the lower limit of the range.

const CContactViewBase & iView

const CContactViewBase & iView [protected]

The sub view's underlying view.
