Class DefaultServices

java.lang.Object
  wt.services.ac.DefaultServices

public final class DefaultServices

extends Object

Provides a convenience mechanism for working with delegation that supersedes the patterns of using factories or otherwise implementing ApplicationContextChild. The APIs of this class are all static (and do not require an instance of the ApplicationContextChild), making it unnecessary to even create a singleton.

Supported API: false

Extendable: false
