MergableAuthenticationInfo (Apache Shiro :: Core 1.7.1 API)

All Superinterfaces:

All Known Implementing Classes:

SimpleAccount, SimpleAuthenticationInfo
```
public interface MergableAuthenticationInfo
extends AuthenticationInfo
```
An extension of the AuthenticationInfo interface to be implemented by classes that support merging with other AuthenticationInfo instances.

This allows an instance of this class to be an aggregation, or composition of account data from across multiple Realms Realms, not just one realm.

This is useful in a multi-realm authentication configuration - the individual AuthenticationInfo objects obtained from each realm can be merged into a single instance. This instance can then be returned at the end of the authentication process, giving the impression of a single underlying realm/data source.
