ObjectStore Active Toolkit Reference

Preface

Purpose

The ObjectStore Active Toolkit Reference provides a reference on the Active Toolkit ActiveX and OLE DB programming interfaces to ObjectStore.

Audience

This book is for experienced Visual Basic, Visual Basic Script, Java, Java Script, or C++ developers who are developing applications that run under Windows NT or Windows 95/98 and want to access objects stored in an ObjectStore database through an ActiveX interface.

Scope

This book supports Release 6.0 of the ATK interface to ObjectStore Release 6.0. Information in this book assumes that ATK is installed and configured.

How This Book Is Organized

ATK and Inspector

When you define data views and instance formats using Inspector, ObjectStore saves them in the metaknowledge. ATK uses the metaknowledge when accessing data views and instance formats. See Chapter 1, ATK and the Inspector.

ActiveX Server

ATK is an ActiveX server that provides access to any ObjectStore database. See Chapter 2, ATK ActiveX Server.

ATK OLE DB

ATK is also an OLE DB provider. OLE DB is a standard interface for accessing data, and ATK provides access to any ObjectStore database through OLE DB. See Chapter 3, Active Toolkit OLE DB Provider.

Configuration

The ATK installation program configures ATK to use the same metaknowledge as Inspector, and assigns several other default settings. If you reconfigure Inspector, you should update the corresponding ATK settings. You can also reconfigure ATK to meet the specific needs of an application. See Chapter 4, Configuring ATK.

ATK object model

The ATK object model consists of 17 COM classes. This chapter lists each class alphabetically by class name. Within the entry for each class, the class's properties and methods appear alphabetically. See Chapter 5, ATK Object Model.
