- - com.yahoo.search.query.profile.CopyOnWriteContent

All Implemented Interfaces:

```
public class CopyOnWriteContent
extends com.yahoo.component.provider.FreezableClass
implements java.lang.Cloneable
```

This may be frozen, at which point no further modifications are allowed. Note that until this is cloned, the internal map may be both read and written.
