Detailed Description

A list of fields.

This class replaces notion of table record, it holds a set of FBwField pointers wich receives data from table or view and are responsible for convertions from database representation to c++ representation of data. A field list can be created from a XSQLDA for exchanging data with fierebird. Also a parameter FieldList can be created for querys with input parameters. Has facilities for copy between field lists based on field order or field names ( remember old cobol MOVE CORRESPONDING! ).

The list has an implicit FieldListIndex wich points to the next field modified by an insertion operator<<. After the insertion the index is incremented and folded to zero when field Count() has been reached. You can alter the order of insertion by inserting a FieldListIndex object with the position you want.
