31 * A mock {@link android.content.ContentResolver} class that isolates the test code from the real
32 * content system.  All methods are non-functional and throw
33 * {@link java.lang.UnsupportedOperationException}.
34 *
35 * <p>This only isolates the test code in ways that have proven useful so far. More should be
36 * added as they become a problem.
