Class Registry

java.lang.Object

com.telenav.kivakit.configuration.lookup.Registry

public class Registry
extends Object

The Registry class allows code to register and locate objects by class and instance (if there is more than one instance). The methods register(Object) and register(Object, Enum) are used to install an object in the lookup and lookup(Class) and lookup(Class, Enum) are used to find an object that has been registered.

Example

In this example, the initialize() method and the doit() method may be in different classes or packages. The doit() method can find the WEB instance of the Server class using lookup(Class, Enum)

 enum Servers { WEB, TRAFFIC, MAP }

 void initialize()
 {
     Registry.of(this).register(new Server(), WEB);
 }

     [...]

 void doit()
 {
     var server = Registry.of(this).lookup(Server.class, WEB);

         [...]
 }
