Method Detail

getConfiguredClass

public static <T> Class<T> getConfiguredClass(Class<T> type,
                                              Properties configuration,
                                              String... implementationDiscriminatorValues)

Retrieves the concrete instance of the class with the given type as configured by the given Configuration. Tries to retrieve a specific implementation first (propery key = fully qualified name of the interface type + '.impl.className.' + implementationDiscriminatorValue). If this key does not exist, the generally configured instance is retrieved (same property key without the implementationDiscriminatorValue).

Parameters:

type - The type of the instance

configuration - The configuration containing the necessary properties for configuring the instance

implementationDiscriminatorValues - The values that define which specific implementation class should be used. This is typically an environment specific property, like the DBMS that is used.

Returns:

The configured class name

getFactoryClass

public static <T> Class<T> getFactoryClass(Class<T> type,
                                           Properties configuration,
                                           String... implementationDiscriminatorValues)
