/**
* Denotes that all parameters, fields or methods within a class or method by
* default can not be null. This can be overridden by adding specific
* {@link com.android.annotations.Nullable} annotations on fields, parameters or
* methods that should not use the default.
* <p/>
* NOTE: Eclipse does not yet handle defaults well (in particular, if
* you add this on a class which implements Comparable, then it will insist
* that your compare method is changing the nullness of the compare parameter,
* so you'll need to add @Nullable on it, which also is not right (since
* the method should have implied @NonNull and you do not need to check
* the parameter.). For now, it's best to individually annotate methods,
* parameters and fields.
* <p/>
* This is a marker annotation and it has no specific attributes.
