Chapter 5. Adapter Class Reference

Chapter 5 provides detailed information on the FJ-JAVA-BASE, FJ-JAVA-CONTROL

and FJ-JAVA-ERROR classes provided by the J adapter class generator, and adapter

classes generated by the J adapter class generator.

Appendix A. Message List

Appendix A explains the messages output by the J adapter class generator, including

the operator responses to the messages.

Appendix B. Exception Type List

The Appendix B describes the types of exception generated by the J adapter class

generator and their remedial measures.

How to Use This Manual

When using the J adapter class generator for the first time, begin to read from

Chapter 1. Chapter 1 provides an outline of the J adapter class generator, Chapter 2

explains the framework, and Chapter 3 explains the procedures from development to

execution.

Chapters 4 and 5 provide detailed information on how to use commands and classes.

Read these chapters for program development.

The Appendix A describes the messages that are output form the J adapter class

generator and the Appendix B describes the exception types that the J adapter class

generator sets. Read them as necessity requires.
