[Java] Class ApplicationBuilder

java.lang.Object
  brooklyn.entity.basic.ApplicationBuilder

@Beta
public abstract class ApplicationBuilder

Experimental mechanism for defining/building applications. In future releases, this API will change. Its concepts will most likely be merged with a TOSCA implementation and with EntitySpec. For building an application. Users can sub-class and override doBuild(), putting the logic for creating and wiring together entities in there. The builder is mutable; a given instance should be used to build only a single application. Once manage() has been called, the application will be built and no additional configuration should be performed through this builder. Example (simplified) code for sub-classing is: app = new ApplicationBuilder() {

Override:: public void doBuild() { MySqlNode db = addChild(EntitySpecs.spec(MySqlNode.class))); JBoss7Server as = addChild(EntitySpecs.spec(JBoss7Server.class) .configure(HTTP_PORT, "8080+") .configure(javaSysProp("brooklyn.example.db.url"), attributeWhenReady(db, MySqlNode.MYSQL_URL)); } }.manage();
