Examples of org.apache.openjpa.lib.util.Options

org.apache.openjpa.lib.util.Options
A specialization of the {@link Properties} map type with the addedabilities to read application options from the command line and to use bean patterns to set an object's properties via command-line the stored mappings. A typical use pattern for this class is to construct a new instance in the main method, then call {@link #setFromCmdLine} with thegiven args. Next, an instanceof the class being invoked is created, and {@link #setInto} is called with that instance as a parameter. With thispattern, the user can configure any bean properties of the class, or even properties of classes reachable from the class, through the command line. @author Abe White @nojavadoc

        // BrokerFactory. This is because it is possible that someone has extended OpenJPA
        // functions and they need to be allowed time to configure themselves before we go off and
        // start instantiating configurable objects (ie:openjpa.MetaDataRepository). Don't catch
        // any exceptions here because we want to fail-fast.
        OpenJPAConfiguration conf = factory.getConfiguration();
        Options o = Configurations.parseProperties(Configurations.getProperties(conf.getMetaDataRepository()));
        if (MetaDataRepository.needsPreload(o) == true) {
            MetaDataRepository mdr = conf.getMetaDataRepositoryInstance(); 
            mdr.setValidate(MetaDataRepository.VALIDATE_RUNTIME, true);
            mdr.setResolve(MetaDataRepository.MODE_MAPPING_INIT, true);
