java.lang.Object

org.xwiki.component.embed.GenericProvider<T>

Type Parameters:

T - the role type

All Implemented Interfaces:

javax.inject.Provider<T>

public class GenericProvider<T>
extends Object
implements javax.inject.Provider<T>

Default provider used when the Component Manager needs to inject a Provider field but no custom Provider has been registered. The default behavior is simply to look up the Component role class when Provider.get() is called. This is useful for example when you wish to do "lazy injection".
