What -are tables

A table is a set of records. All records in a table are the same type. -A table is also a container and an element.

There are two types of table:

a table that has records -defined at system compile time - these records have named fields and are defined -by Symbian platform.
a table that consists -of records defined at run time - these records are user defined records - -they are not known to Symbian platform when Symbian platform is built.

Tables that have records defined at system compile - time

A table that has records defined at system compile time -is represented by the templated class CMDBRecordSet <T>. -The template parameter defines the record type. The template parameter is -a Symbian platform defined record.

You create a table -object on the heap. You use the new (Eleave) construction -to create this object.

- -

The CommsDat API implements the table as an array of records and -uses RPointerArray <T> as -the array. The CommsDat API implements RPointerArray<T> in -the base class CMDBRecordSetBase, because -this behaviour is common to all tables. Tools and applications can access -the array and can use the sort behaviour provided by RPointerArray<T> to -sort records.

Tables that have user defined records

A table that -has user defined records is represented by the CMDBGenericRecord. -The class has the behaviour that allows it to represent a record and a set -of records. Internally, the class has an array that can contain the records.

You -use the CommsDat::CCDRecordBase::RecordFactoryL() factory -function to create a CMDBGenericRecord object.
