Class StringManagerFactory

java.lang.Object
oracle.jbo.common.StringManagerFactory

public class StringManagerFactory

extends java.lang.Object

The factory for creating StringManager instances.

This class is used by the framework to create an instance when the client attempts to establish a connection to the database. Applications may provide custom StringManager implementations. Such applications will need to subclass this class and StringManagerImpl.

The framework calls the getFactory() method to get the currently installed factory, and calls its create() method to establish a connection.

This class has a single active instance, which cannot be replaced.

Since:

JDevloper 3.0
