CContactItem Class Reference

class CContactItem : public CBase

The abstract base class for contact cards, templates and groups. All contact items are identified by a contact ID, (TContactItemId), have a last modified date/time and own one or more fields (the field set). Contact items also have an access count and attributes (e.g. hidden). Note that fields in a contact item also have attributes. Attribute values specified in the contact item override those in the contained fields. The access count is a record of the number of objects referencing a contact item. A contact item cannot be fully deleted until its access count is zero.

SetLastModified(const TTime &)

IMPORT_C void

SetLastModified

(

const TTime &

aLastModified

)

Sets the last modified date/time value stored in the local copy of the contact item. This value is returned by LastModified() for this copy of the item.

Parameters

TDesC & aString

The contact item's UID string.

TemplateRefId()

UidStringL(TInt64)

IMPORT_C TPtrC

UidStringL

(

TInt64

aMachineUniqueId

)

const

Returns a descriptor which contains the item's UID string. Contact items have a globally unique identifier, stored as a descriptor. This is provided for vCard support. It is a combination of the database's unique identifier, the contact item ID and the date/time of the contact item's creation.

Parameters

TInt64 aMachineUniqueId

The database's unique identifier. This can be retrieved using CContactDatabase::MachineId().

UpdateFieldSet(CContactItemFieldSet *)

IMPORT_C void

UpdateFieldSet

(

CContactItemFieldSet *

aNewFieldSet

)

Replaces the contact item's field set.

Parameters

CContactItemFieldSet * aNewFieldSet

The new field set with which to replace the existing one.
