Interface SingletonAccessor

public interface SingletonAccessor

A deployment specific reference to a SandRoot. During startup, the application will typically create an instance of a class implementing this interface to serve as a common reference to the SandRoot when bridging between UI display adaptors and the core application.

In addition to providing the declared interface methods, an implementing class is expected to provide a static accessor that can be used to retrieve a singleton instance of itself.

Method Summary

java.lang.String	getDeploymentPrefix() Return the prefix for this deployment.
SandRoot	getSandRoot() Return the SandRoot instance or null if not initialized yet.
void	init(SandRoot root) Set the global SandRoot reference.
