Adds a new data time field to contact asynchronously.

Adds a new text field to contact asynchronously.

Adds a new binary field to contact asynchronously.

Handles the committing of the contact. This is called after adding fields to contact because it's possible that the policy needs still e.g split the contact.

Returns an extension point for this interface or NULL.

Copies the contact to the target store. All possible data is copied. The difference to CommitContactL is that if you already have a contact that contains data then you don't need call AddFieldToContactL operations but this can be called instead.

Copies title fields from source contact to the target contact. Policy defines the title field types. The field is not copied if the contact already contains the same type of title field.

Merges source contacts to target contact if possible. Handles saving the existing contact and possible new contacts. The logic is defined by the policy. Client gets the links of the contacts that were actually saved.

SupportsContactMerge()

Returns ETrue if contact data merge is supported. This will disable duplicate contact saving in clients because duplicates need to be merged with new contacts.
