Defines a way of grouping fields to form a string which represents a contact item.

A text definition is implemented as an array of text definition items (TContactTextDefItems).

For example, CContactDatabase::ReadContactTextDefL() uses a text definition to build up a string from a contact item. When creating the string, it searches the item for fields whose type matches one of the fields specified in the text definition. The contents of the first matching field of each type found in the item are read into the string. These strings may be separated using a field separator, which is also specified in the text definition. A separator is not appended to the last field used to make up the string. It is only inserted when there is a following non-empty field.

Additionally, the text definition may also contain a fallback field type. This is used when none of the fields specified in the text definition contain any text. If the item's fallback field contains no text either, or if the fallback field type's value is KUidContactFieldNone, the text is read from the first non-empty field in the item.

A contact database can have a default text definition which is set using CContactDatabase::SetTextDefinitionL(). This may be overridden using the variants of CContactDatabase::ReadContactTextDefL() which take a CContactTextDef* argument.

CContactTextDef is derived from CArrayFixFlat<TContactTextDefItem>, so all relevant functions can be used, e.g. to add and remove elements.
