Class CContactViewRangeBase

class CContactViewRangeBase : public CBase;

Description

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.

Derivation

• CBase - Base class for all classes to be instantiated on the heap

• CContactViewRangeBase - The abstract base class for all contact view range classes

Members

Defined in CContactViewRangeBase:

• EGreaterThanGreater than
• EGreaterThanOrEqualToGreater than or equal to
• ELessThanLess than
• ELessThanOrEqualToLess than or equal to
• HighIndex()Gets the index into the sub view's underlying view of the item at the top of the range
• IndicesValid()Tests whether the lower and upper indexes are valid, i.e
• LowIndex()Gets the index into the sub view's underlying view of the item at the bottom of the range
• SetL()Sets the iLow and iHigh members
• TCriteriaDefines the range criteria
• iCollateMethodThe collation method used to sort the strings
• iHighThe index into the sub view's underlying view of the item at the upper limit of the range
• iLowThe index into the sub view's underlying view of the item at the lower limit of the range
• iViewThe sub view's underlying view

Inherited from CBase:

• Delete()Deletes the specified object
• Extension_()Extension function
• operator new()Initialises the object to binary zeroes

See also:

• CContactSubViewProvides a view of a range of contact items from a potentially larger underlying view (another CContactViewBase-derived object)

inline TInt LowIndex() const;

Description

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

Return value

TInt The index of the item at the bottom of the range.

inline TInt HighIndex() const;

Description

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

Return value

TInt The index of the item at the top of the range.

virtual void SetL()=0;

Description

Sets the iLow and iHigh members.

IMPORT_C TBool IndicesValid() const;

Description

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

Return value

TBool ETrue if the indexes are valid, EFalse if not.

TCriteria

Description

Defines the range criteria.

ELessThan Less than. ELessThanOrEqualTo Less than or equal to. EGreaterThan Greater than. EGreaterThanOrEqualTo Greater than or equal to.

protected: const CContactViewBase & iView;

Description

The sub view's underlying view.

protected: TInt iLow;

Description

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

protected: TInt iHigh;

Description

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

protected: TCollationMethod * iCollateMethod;

Description

The collation method used to sort the strings.

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