Class HigginsRegistry

java.lang.Object
  org.eclipse.higgins.registry.HigginsRegistry

public abstract class HigginsRegistry

extends Object

A registry for service provider instances. A service is an interface which extends IServiceProvider interface. A service provider is a specific implementation of a service. The classes in a provider implement the interface defined by the service.

Higgins Registry uses registry extensions to lookup for available service providers.

When base implementation is constructed it doesn't contain any registry extensions and so, requires additional configuration. For example:

 HigginsRegistry<IServiceProvider> r = new HigginsRegistry<IServiceProvider>();
 r.addExtension(new IIORegistryExtension<IServiceProvider>(
 		IServiceProvider.class));
 r.loadProviders();
