Method Detail

get

public T get()

Description copied from interface: Configuration

Retrieves the user configuration instance managed by this Configuration.

Even if the user configuration is initialized from properties file, the consistency rules of Polygene composites still applies. If the the properties file is missing a value, then the initialization will fail with a RuntimeException. If Constraints has been defined, those will need to be satisfied as well. The user configuration instance returned will fulfill the constraints and consistency normal to all composites, and can therefor safely be used with additional checks.

Specified by:

get in interface Configuration<T>

Returns:

The fully initialized and ready-to-use user configuration instance.

refresh

public void refresh()

Description copied from interface: Configuration

Updates the values of the managed user ConfigurationComposite instance from the underlying org.apache.polygene.spi.entitystore.EntityStore. Any modified values in the current user configuration that has not been saved, via Configuration.save() method, will be lost.

Specified by:

refresh in interface Configuration<T>

save

public void save()

Description copied from interface: Configuration

Persists the modified values in the user configuration instance to the underlying store.

Specified by:

save in interface Configuration<T>
