EvaluatorFactory (Dataflow Library Distribution Project 8.2.0-176 API)

All Known Implementing Classes:

InputMappedFactory, MappedEvaluatorFactory, ReflectiveFactory, ResultMappedFactory
```
public interface EvaluatorFactory
```
A factory used to construct evaluators for ScalarValuedFunctions. A number of implementations are provided which cover common use cases.
An EvaluatorFactory is used as part of a function description to provide a mechanism for creating evaluators for associated function instances. Because descriptions are serialized within the framework, implementations of EvaluatorFactory must also be serializable as JSON.
