   216 a contact item.

   217 

   218 A text definition is implemented as an array of text definition items

   219 (TContactTextDefItems).

   220 

   221 For example, CContactDatabase::ReadContactTextDefL() uses a text definition to

   222 build up a string from a contact item. When creating the string, it searches

   223 the item for fields whose type matches one of the fields specified in the text

   224 definition. The contents of the first matching field of each type found in the

   225 item are read into the string. These strings may be separated using a field

   226 separator, which is also specified in the text definition. A separator is not

   227 appended to the last field used to make up the string. It is only inserted when

   228 there is a following non-empty field.

   229 

   230 Additionally, the text definition may also contain a fallback field

   231 type. This is used when none of the fields specified in the text

   232 definition contain any text. If the item's fallback field contains no text

   233 either, or if the fallback field type's value is KUidContactFieldNone, the

   234 text is read from the first non-empty field in the item.

   235 

   236 A contact database can have a default text definition which is set using CContactDatabase::SetTextDefinitionL().

   237 This may be overridden using the variants of CContactDatabase::ReadContactTextDefL()

   238 which take a CContactTextDef* argument.

   239 

   240 CContactTextDef is derived from CArrayFixFlat<TContactTextDefItem>, so all

   241 relevant functions can be used, e.g. to add and remove elements.

   569 /** A database of contact items.

   570 

   571 Contact items can be added to and removed from the database and items in the

   572 database can be opened or read. To edit an item, it must first be opened.

   573 Changes to the item can then be committed using CommitContactL()

   574 (committing can only take place to an open item).

   575 

   576 If the available disk space is less than 128 kilobytes then changes to the

   577 contact database cannot be started, and methods such as CreateL() or CommitContactL()

   578 will leave with a KErrDiskFull error. Less obviously OpenL() can also fail with

   579 KErrDiskFull when trying to update the system template.

   580 

   581 Each item has an access count. An item cannot be fully deleted unless its

   582 access count is zero. This is to prevent items which have been

   583 synchronised with another contacts application from being deleted.

   584 Also, if the item is a template, it cannot be deleted if other items are based

   585 on it.

   586 

   587 More than one contact database can exist on a phone, but there is a

   588 default contact database. Its filename is contacts.cdb. It

   589 can be moved between drives.

   590 

   591 CContactDatabase implements searching and sorting and also provides

   592 separate phone number matching functions. These provide a fast way of indexing

   593 and looking up phone numbers, e.g. for looking up caller IDs on incoming

   594 calls.

   595 

   596 The database owns speed dial information. This is a mapping between a single

   597 digit integer and a telephone number. There may be up to 9 speed dial telephone

   598 numbers; each of them belongs to a contact item in the database. If a

   599 contact item is deleted, its speed dial mapping is removed.

   600 

   601 The following functions defined in class CContactDatabase are not

   602 supported. If called, they leave with KErrNotSupported.

   603 

   604 - ReplacePrefL()

   605 

   606 - ReadPrefL()
