http://issues.apache.org/bugzilla/show_bug.cgi?id=34353 Summary: [configuration]Provide support for declaring and creating objects Product: Commons Version: unspecified Platform: Other OS/Version: other Status: NEW Severity: enhancement Priority: P2 Component: Configuration AssignedTo: commons-dev@jakarta.apache.org ReportedBy: [EMAIL PROTECTED] A useful enhancement for the configuration API could be a way to create and initialize objects whose class and initialization parameters are defined in a configuration file. The idea is that both the class name and initialization parameters for an object are defined in a standard format. A createObject(String key) method (which might fit best in DataConfiguration?) would extract the class name from the specified property, create the object using reflection and then populate properties via [beanutils]. For the concrete format for declaring objects in a configuration file there are many possibilities. We have to define a format which is easy to use, but although suports complex initialization parameters. A possible object declaration could look as follows (here in XML flavour, but other configuration sources are of course possible, too): <myobject> <class>package.ClassName</class> <args> <arg1>value1</arg1> <arg2>value2></arg2> ... </args> </myobject> We could even go a step further and define an interface public interface Configurable { void initialize(Configuration config); } If the newly created object implements this interface, its initialize() method will be called and a sub configuration will be passed that contains the content of the <args> section. This would allow for arbitrary complex and also hierarchical initialization parameters. It's a bit similar to what IoC frameworks do. Side note: If we add more features to the configuration definition files processed by ConfigurationFactory (e.g locators or declarations for reloading strategies) and use a XMLConfiguration to load these files, the proposed object creation facility may come in handy. -- Configure bugmail: http://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
