Class MultiConfig

java.lang.Object
  pt.ist.fenixframework.MultiConfig

public class MultiConfig
extends Object

Stores multiple Fenix Framework Configurations. Each configuration is automatically associated with a key obtained by invoking BackEnd.getName() on the config's BackEnd. Setting up multiple configurations allows the Fenix Framework to automatically choose the configuration to use, according to the backend that generated the domain model. For this mechanism to work as expected when using explicit initialization (see FenixFramework), the programmer must initialize the framework by invoking the FenixFramework.initialize(MultiConfig) method (instead of FenixFramework.initialize(Config)). Before doing so, however, the programmer must create an instance of MultiConfig and add each of the available configurations (via add(Config)). NOTE: This class is not thread-safe. It is not expectable to have multiple threads attempting to concurrently add configurations the same MultiConfig instance. However, it is possible (albeit of questionable usefulness) to attempt initialization of the framework from multiple threads, each using a different instance of MultiConfig.
