* This class defines a {@code java.util.ServiceLoader} service which enables programmatic * configuration of the Jakarta Server Faces runtime using the existing Application Configuration Resources schema. * See the section "Application Startup Behavior" in the specification prose document for the * specification on when and how implementations of this service are used. *

* * @since 2.2 * */ public abstract class ApplicationConfigurationPopulator { /** *

* Service providers that implement this service must be called by the Jakarta Server Faces runtime exactly once * for each implementation, at startup, before any requests have been serviced. Before calling * the {@link #populateApplicationConfiguration} method, the runtime must ensure that the * {@code Document} argument is empty aside from being pre-configured to be in the proper * namespace for an Application Configuration Resources file: {@code * http://xmlns.jcp.org/xml/ns/javaee}. Implementations of this service must ensure that any * changes made to the argument {@code * Document} conform to that schema as defined in the specification. The Jakarta Server Faces runtime is not * required to validate the {@code Document} after control returns from the service * implementation, though it may do so. *

* *
* *

* Ordering of Artifacts *

* *

* If the document is made to contain an {@code } element, as specified in the section * Ordering of Artifacts in the specification prose document, the document will be * prioritized accordingly. Otherwise, the runtime must place the document in the list of other * Application Configuration Resources documents at the "lowest" priority, meaning any conflicts * that may arise between the argument document and any other Application Configuration * Resources are resolved in favor of the other document. *

* *
* * @param toPopulate The Document to populate with configuration. * * @since 2.2 */ public abstract void populateApplicationConfiguration(Document toPopulate); }
