Class OA

java.lang.Object

com.arjuna.orbportability.OA

Direct Known Subclasses:

ChildOA, RootOA

public abstract class OA
extends Object

An attempt at some ORB portable ways of interacting with the OA. NOTE: initPOA *must* be called if you want to use the pre- and post- initialisation mechanisms.

Since:

JTS 2.1.
