Class DNSServerFactory

java.lang.Object
  org.nhindirect.dns.DNSServerFactory

public class DNSServerFactory
extends Object

The DNSServerFactory is a bootstrapper for creating instances of the DNSServer) based on configuration information. Configurations are loaded from a URL that may take the form of any addressable resource such as a file, HTTP resource, LDAP store, or database. Based on the URL protocol, an appropriate configuration loader and parser is instantiated which creates an injector used to provide instance of the DNSServer. Optionally specific configuration and {@link DNSStore} providers can be passed for specific object creation. This is generally useful for creating mock implementations for testing.
