So if FooBinding had getBar/setBar then there + * would be an attribute name 'bar', for example, <binding.foo bar="xxx">. + * + * BindingActivator implementations may use constructor arguments to have + * Tuscany ExtensionPointRegistry objects passed in on their constructor. + * For example: + * + * public class MyBindingActivator implements BindingActivator { + * ServletHost servletHost; + * public MyBindingActivator(ServletHost servletHost) { + * this.servletHost = servletHost; + * } + * ... + * } + * + * BindingActivator implementations are discovered by the Tuscany runtime + * using the J2SE jar file extensions for service provider discovery.
