Objects and Collections

This chapter discusses how Oracle SQLJ supports user-defined SQL types--namely objects (and related object references) and collections (variable arrays and nested tables). This includes discussion of the Oracle JPublisher utility, which you can use to generate Java classes corresponding to user-defined SQL types.

The following topics are discussed:

• Introduction

• Oracle Objects and Collections

• Custom Java Classes

• User-Defined Types in the Database

• JPublisher and the Creation of Custom Java Classes

• Strongly Typed Objects and References in SQLJ Executable Statements

• Strongly Typed Collections in SQLJ Executable Statements

• Serializing Java Objects

• Weakly Typed Objects, References, and Collections
