Message (Analytics for Java (Core) 3.5.4 API)

All Known Implementing Classes:

AliasMessage, GroupMessage, IdentifyMessage, PageMessage, ScreenMessage, TrackMessage
```
public interface Message
```
Encapsulates properties common to all messages. Although not enforced by the compiler, either the anonymousId() or userId() must be provided.
For any functions that accept a map, such as integrations(), context(), TrackMessage.properties(), ScreenMessage.properties(), IdentifyMessage.traits(), or GroupMessage.traits(), we'll make an internal copy of the map provided. If you use Guava, we'll use it's ImmutableMap#copyOf methods instead.
There are a few limitations to be aware of when using Guava — mainly that null keys or values are not permitted and duplicate keys are not permitted. For more details, refer to Guava's Javadocs.
