Examples of EmbeddedEntity

com.google.appengine.api.datastore.EmbeddedEntity
A property value containing embedded entity properties (and optionally a {@link Key}). This class is similar to {@link Entity}, but differs in the following ways:
- {@link #equals(Object)} and {@link #hashCode()} compare the embeddedproperties in addition to the {@link Key}.
- It is not queryable when stored in the datastore.
- A {@link Key} is optional.
- {@link Key Keys} without a name or id are considered equal if all otheraspects of the keys are equal (as they will not be assigned IDs by the datastore when embedded).
To convert from an {@link Entity} use:
```
  {@code EmbeddedEntity sv = new EmbeddedEntity(); sv.setKey(entity.getKey()) sv.setPropertiesFrom(entity)}
```
To convert to an {@link Entity} use:
```
  {@code Entity entity = new Entity(sv.getKey()) entity.setPropertiesFrom(sv);}
```
