Chapter 4. Instance lifecycle
“Here come the state transition diagrams!”
—Robin M. Roos
The Java Data Objects Training Course
The lifecycle of a JDO instance is governed by a series of states and associated state transitions. During this chapter we examine each of those states, and the code that an application might use in order to effect each state transition. By studying these you will learn how to manipulate instances within your application, and gain a greater understanding of the underlying technology.
