- com.bayesserver.inference.QueryFunction

```
public final class QueryFunction
extends Object
```
Defines a function to be evaluated in a call to Inference.query(com.bayesserver.inference.QueryOptions, com.bayesserver.inference.QueryOutput). Functions do not form part of the core inference routine, but are evaluated afterwards in topological order.
