DefaultStorageProvider

java.lang.Object
- org.apache.james.mime4j.storage.DefaultStorageProvider

```
public class DefaultStorageProvider
extends java.lang.Object
```
Allows for a default StorageProvider instance to be configured on an application level.
The default instance can be set by either calling setInstance(StorageProvider) when the application starts up or by setting the system property org.apache.james.mime4j.defaultStorageProvider to the class name of a StorageProvider implementation.
If neither option is used or if the class instantiation fails this class provides a pre-configured default instance.
