Overview

The concept of a form set in the forms processing world is described simply as a collection of zero or more forms. FormDirector implements this concept as the type FormSet. This type exposes several parameters to allow storage of various attributes of a form set.

FormDirector also implements the type FormSetFile, which derives from the FormSet type and adds the capability to write and read itself from persistent storage.

Purpose

The primary purpose of the FormSet type is to represent a collection of forms, in order to support form identification. As a result, the core part of a FormSet is a collection of FormDefinitions, the FormDefinitions property. If you do not need to perform form identification, then you probably do not need to use a FormSet object and can rely instead on one or more FormDefinition objects.

A secondary purpose of a FormSet is to hold data, including a name of the form set, parameters for form identification, parameters for other image operations, and some miscellaneous data.

The FormSet class is an abstract class which defers the details of reading and writing form set files to a derived class. FormDirector provides a derived class, FormSetFile, which implements reading and writing data to files for persistent storage. You can create your own derived classes to manage reading and writing to other locations, such as a web server or database.
