Evaluator

All Superinterfaces:

java.lang.AutoCloseable
```
public interface Evaluator
extends java.lang.AutoCloseable
```
Evaluator interface. An implementation of this is used during evaluation of all expressions for one component descriptor as needed. This does not need to be thread safe and it will not be used across component descriptors without receiving intermediate init/destroy calls.
