The methods `getClientStorageProviders`, `getClientStorageProvidersStream`, `getRoleStorageProviders` and `getRoleStorageProvidersStream` have been removed as well.
Code which depends on these methods and runs with the legacy storage enabled should cast the instance as follows:
.Before migration: code will not compile due to the changed API
[source,java,subs="+quotes"]
----
realm**.getClientStorageProvidersStream()**...;
----
.After migration: cast the instance to the legacy interface
[source,java,subs="+quotes"]
----
((LegacyRealmModel) realm)**.getClientStorageProvidersStream()**...;
----
Similarly, code that used to implement the interface `RealmModel` and wants to provide these methods should implement the new interface `LegacyRealmModel`. This interface is a sub-interface of `RealmModel` and includes the old methods:
.Before migration: code implements the old interface
[source,java,subs="+quotes"]
----
public class MyClass extends RealmModel {
/* might not compile due to @Override annotations for methods no longer present
in the interface RealmModel. */
/* ... */
}

.After migration: code implements the new interface

public class MyClass extends LegacyRealmModel {
/* ... */

== Interface `UserCache` moved to the legacy module
As the caching status of objects will be trasparent to services, the interface `UserCache`
