Unique class

Enforces that the value of a property is unique among all objects in a box before an object can be put.

Trying to put an object with offending values will result in a UniqueViolationException (see ConflictStrategy.fail). Set onConflict to change this strategy.

Note: Unique properties are based on an Index, so the same restrictions apply. It is supported to explicitly add the Index annotation to configure the index.
